P0062 on 2013-2016 Jaguar XJ: HO2S Heater Circuit Causes and Fixes

What's Unique About the 2013-2016 Jaguar XJ

For the 2013-2016 Jaguar XJ with the V6 or V8 engine, this code is not just a simple sensor failure. Jaguar issued technical service bulletin JTB-00392-NAS-3 indicating that a software error in the Powertrain Control Module (PCM) is a primary cause. This means that simply replacing the oxygen sensor may not provide a permanent fix; a crucial PCM software update is often required to prevent the new sensor from failing prematurely or the code from returning. This issue is common across other JLR models with the same engines.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Check Engine Light is on
• Reduced fuel economy
• Rough idle or poor performance, especially during a cold start before the sensor warms up naturally
• Failure to pass an emissions test
• Noticeable black soot on the inside of the exhaust tips, indicating a rich running condition.

Most Likely Causes

1. Failed Bank 2, Sensor 3 Oxygen Sensor 🔴 High Probability → Shop Oxygen Sensor The sensor's internal heater element is the most common point of failure. Forum users frequently report this specific sensor failing. The PCM software issue noted in TSBs may also contribute to premature failure. Land Rover, a sister brand using the same engines, also acknowledged manufacturing defects in the sensors themselves.
   How to confirm: After confirming wiring is intact, test the resistance of the sensor's heater circuit using a multimeter. The two same-colored wires are typically for the heater. A reading outside the typical specification (which varies from 1-2 ohms to 11-16 ohms depending on the source) or an open circuit indicates a failed heater. The TSB procedure is to replace the sensor if the code is present.
   Typical fix: Replace the Bank 2, Sensor 3 oxygen sensor and clear the trouble codes. A PCM software update is highly recommended at the same time. A special 22mm O2 sensor crowfoot wrench is required.
   Est. part cost: $50-$200
2. Outdated Powertrain Control Module (PCM) Software 🔴 High Probability → Shop Engine Control Module (ECM) Jaguar identified a software error as a direct cause for this and a host of other HO2S codes, as detailed in TSB JTB-00392-NAS-3. The bulletin explicitly states the fix is to replace the sensor AND update the software.
   How to confirm: A Jaguar dealer or a qualified independent shop with access to Jaguar's diagnostic software (SDD/TOPIx) can check the current software version against the latest available version mentioned in the TSB.
   Typical fix: Update the PCM software to the latest version using the 'Configure existing module - Powertrain control module' function in the dealer software. This is often done in conjunction with replacing the faulty sensor.
   Est. part cost: $150-$400 for dealer labor, may be included if sensor is replaced under warranty.
3. Wiring or Connector Damage ⚪ Low Probability While possible due to proximity to hot exhaust components, Jaguar TSB SSM72477 notes that diagnosis often reveals no fault with the wiring or connectors, pointing instead to the sensor or software. However, visual inspection is still a crucial first step.
   How to confirm: Visually inspect the wiring harness and connector for the Bank 2, Sensor 3 O2 sensor for any signs of melting, corrosion, or physical damage. Check for stable 12V power and a solid ground at the connector with the ignition on.
   Typical fix: Repair the damaged section of the wiring harness or clean/replace the connector.
   Est. part cost: $5-$50

Rare But Worth Checking

• Blown Fuse for O2 Sensor Heater Circuit: → Shop Oxygen Sensor A simple but sometimes overlooked possibility. Always check the fuse box for any blown fuses related to the emissions or engine control systems before replacing parts. The fuse location can be found in the owner's manual or a service manual.
• Faulty Powertrain Control Module (PCM): → Shop Engine Control Module (ECM) This is very rare. The PCM should only be considered after all other possibilities, including the software update, have been exhausted and confirmed by a professional.

Diagnosis Steps

1. Connect an OBD-II scanner to confirm the P0062 code and check for any other related codes.
2. Check for eligibility for Jaguar TSB JTB-00392-NAS-3 or related bulletins. This is the most important step for this specific vehicle and its platform mates.
3. Locate the Bank 2, Sensor 3 oxygen sensor. It is on the driver's side of the vehicle (on LHD models), downstream of the catalytic converter. Access is from underneath the car, roughly below the driver's seat.
4. Visually inspect the sensor's wiring and connector for any signs of melting, chafing, or corrosion.
5. If wiring appears intact, test the resistance of the heater circuit 🎬 Watch: How to test and diagnose a P0062 code pins on the sensor itself using a multimeter. An open circuit (OL) or a reading far from the typical 1-16 ohm range confirms a failed heater element.
6. If the sensor tests good, check for 12V power and ground at the vehicle-side harness connector with the ignition on. If power is missing, check the relevant fuse.
7. If the sensor has failed, replace it. A 22mm crowfoot or slotted oxygen sensor socket is required.

8. After replacement, have a Jaguar dealer or qualified shop with JLR diagnostic tools perform the 'Configure existing module - Powertrain control module' option to update the software per TSB JTB-00392-NAS-3.
9. Clear all diagnostic trouble codes and perform a drive cycle to ensure the code does not return.

Parts You'll Likely Need

• Heated Oxygen Sensor (Bank 2, Sensor 3) (OEM #C2D54169 (for RWD models), C2D54165 (for AWD models)) — This is the component identified by the code and is the primary hardware failure point. TSBs instruct to replace it if the code is present. Part numbers for left (Bank 2) and right (Bank 1) sensors are different due to mirrored connector shapes, even if the sensor itself is identical. Always verify the part number with your vehicle's VIN.
  Trusted brands: Jaguar (OEM), Bosch (often the OEM supplier), Denso, NTK
  OEM price range: $150-$250
  Aftermarket price range: $50-$120

Related Codes That Often Appear With This One

• P0162 — P0162 is a general circuit malfunction for the same sensor (Bank 2, Sensor 3). They often appear together as they point to the same component's failure.
• P0163 — Indicates low voltage from the Bank 2, Sensor 3, pointing to a failure in the same sensor or its circuit.
• P0164 — Indicates high voltage from the Bank 2, Sensor 3, also pointing to a failure in the same sensor or its circuit.
• P0042 — This is the equivalent heater circuit code for the other side of the vehicle (Bank 1, Sensor 3). It is common for these sensors to fail around the same time.

Technical Service Bulletins (TSBs) & Recalls

• JTB-00392-NAS-3: The primary TSB for this issue. States the cause may be a software error and instructs technicians to replace the relevant sensor and then update the PCM software using the SDD/TOPIx diagnostic tool.
• JTB00392NAS1: An earlier version of the same bulletin with similar instructions.
• SSM72477: Notes that upon diagnosis, often no fault is found with the wiring or connector, implying the issue is with the component itself or software.
• Land Rover TSBs (SSM72556, LTB00671NAS3): Bulletins for platform mates that acknowledge sensor quality issues and list P0062 as a known fault code, corroborating the issue across the JLR family.

Platform-Specific Known Issues

• A known software glitch in the Powertrain Control Module can falsely trigger P0062 and other HO2S codes. Jaguar released TSB JTB-00392-NAS-3 to address this, which involves replacing the affected sensor and reprogramming the PCM.
• An extended warranty for O2 sensors was issued by Jaguar Land Rover North America for some models, which may cover the cost of this repair. Owners should check with a dealer for eligibility based on their VIN and vehicle in-service date.

Mechanic-Grade Diagnostic Values

• O2 Sensor Heater Circuit Resistance — expected: Varies by source. Some generic guides state 5-20 Ohms, while others suggest a tighter range of 1-2 Ohms or 11-16 Ohms based on a factory service manual.. Failure: A reading of infinity (open circuit) or a value significantly outside the specified range indicates a failed heater element.
• Voltage at O2 Sensor Heater Power Wire — expected: Approximately 12V (battery voltage) with key on, engine off.. Failure: Low or no voltage indicates a problem with the fuse, relay, or wiring harness leading to the sensor.
• Voltage at O2 Sensor Heater Ground Wire (Control Side) — expected: This is a pulse-width modulated (PWM) ground controlled by the PCM. When testing with a test light connected to battery positive, the light should flash or illuminate when the heater is commanded on (typically on a cold start).. Failure: No activity on the ground control wire suggests a wiring issue back to the PCM or a faulty PCM driver.

Hidden / Shadow Codes Worth Checking

• N/A: While no specific shadow codes for P0062 were found, codes may not appear in the main 'Related Events' list in the Jaguar SDD software if the technician does not select the correct symptoms at the start of the session. Hidden or seemingly unrelated codes may be found in the 'Unrelated Events' section. (see via Jaguar SDD (Symptom Driven Diagnostics) software.)

Scan Tool Commands That Help

• Jaguar SDD (Symptom Driven Diagnostics): Configure existing module - Powertrain control module — This is the specific function required by TSB JTB-00392-NAS-3 to update the PCM software after replacing the oxygen sensor. It flashes the module with the latest calibration to correct the underlying software fault.
• Jaguar SDD (Symptom Driven Diagnostics): Data Logger / Live Monitoring — To observe the live voltage or current of the O2 sensor circuits. A technician can use this to see if the sensor is responding and if the heater circuit is drawing current as expected. A flatline reading on a warm sensor indicates a problem.
• Jaguar SDD (Symptom Driven Diagnostics): Install new module — This function is used when installing a brand new, virgin module. For this specific P0062 issue, the 'Configure existing module' command is more appropriate as per the TSB, but this is the correct path for a complete PCM replacement.

Wiring & Ground Locations

• G4d197as — Under the vehicle, at the center rear.. This is a chassis ground point in the vicinity of the rear (Sensor 3) oxygen sensors. A corroded or loose ground here could potentially affect the sensor's circuit, as a poor ground can cause incorrect voltage readings and trigger heater circuit codes.
• O2 Sensor Connector — On the wiring harness near the Bank 2, Sensor 3 location, under the driver's side of the vehicle.. This is where voltage and resistance tests are performed. The heater circuit wires are typically the two same-colored wires. One should have ~12V with the key on, and the other is the PCM-controlled ground.

Real Owner Repair Stories

• JaguarForums.com user 'Kruzer' (2015 XF 3.0 AWD (platform mate with same engine/systems)) — P0062 code, slight coolant smell (which turned out to be an unrelated issue).
  ❌ Tried (didn't work) Initial diagnosis was uncertain.
  ✅ What actually fixed it The P0062 code was resolved by replacing the Bank 2, Sensor 3 oxygen sensor. The user noted it took about 30 minutes and required a 22mm crowfoot wrench. They also confirmed that the left and right side sensors have different connectors.

OEM Part Supersession History

• C2D54169 → J9C26105 — Standard part update/revision.
  Heads up: The superseding part J9C26105 is listed as 'Unavailable' on the Jaguar Classic Parts website as of early 2026, which may complicate sourcing OEM parts for RWD models.
• c2d24757, c2d27350 → C2D54165 — Standard part update/revision for AWD models.

Model Year Variations Within This Range

• 2013-2016: The primary part variation is based on the drivetrain. RWD models use a different downstream oxygen sensor (C2D54169) than AWD models (C2D54165) due to different connector shapes or harness lengths.
