C1709 on 2014-2015 Infiniti Q60: Front Right TPMS Sensor 'No Data' Causes and Fixes

What's Unique About the 2014-2015 Infiniti Q60

The Infiniti Q60 and related platforms (G37, 370Z) are known to be susceptible to radio frequency (RF) interference, which can block the 315MHz TPMS sensor signals and trigger a C1709 code. Infiniti issued a Technical Service Bulletin (ITB13039A, also referenced in NTB13-088) specifically to address this issue, noting that aftermarket electronics like phone chargers are often the cause. Forum users on MyG37.com and other platforms have confirmed that unplugging a cheap or faulty USB charger often resolves the issue instantly. A less common but documented cause of RF interference on the related Nissan 370Z is a failing HVAC blower motor, as noted in TSB NTB19-062.

Diagnostic Flowchart

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

Symptoms You May Notice

• TPMS warning light flashes for approximately one minute on startup, then stays on solid.
• Vehicle information display shows dashes (--) instead of a pressure reading for the front right tire.
• "Check Tire Pressure" warning message may appear in the vehicle information display.

Most Likely Causes

1. Dead TPMS Sensor Battery 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor The original sensors contain non-replaceable batteries with a finite lifespan of 7-10 years. For a 2014-2015 vehicle, battery failure is expected due to age, making this the most common cause.
   How to confirm: Use a TPMS diagnostic tool to attempt to 'wake up' or read the sensor. If the tool receives no signal or shows a low battery status, the sensor battery is dead. Tire shops like Discount Tire will often perform this check for free.
   Typical fix: Replace the front right TPMS sensor and register the new sensor ID to the vehicle. It is often recommended to replace all four sensors at once, as the others are likely to fail soon.
   Est. part cost: $40-$120
2. Radio Frequency (RF) Interference 🟡 Medium Probability As documented in TSB ITB13039A, these vehicles are sensitive to RF noise from aftermarket devices (phone chargers, dash cams, wireless phone mounts) plugged into the 12V outlets, which can block the 315MHz TPMS signal. Owners on forums frequently report that cheap, unshielded USB chargers are the culprit.
   How to confirm: Unplug ALL aftermarket electronics from the vehicle's power outlets. Clear the codes (if you have a scanner) or simply drive for 10-15 minutes above 25 MPH to see if the light stays off. If the light goes out, the issue is one of the unplugged devices.
   Typical fix: Remove or replace the interfering electronic device with a higher-quality, well-shielded one.
   Est. part cost: $0
3. Damaged TPMS Sensor ⚪ Low Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor Sensors can be physically damaged during tire mounting/dismounting or by severe pothole impacts. The valve stem itself can also be a point of failure.
   How to confirm: Visual inspection after dismounting the tire. The sensor may show cracks or other signs of physical damage. A slow leak may also indicate a damaged seal.
   Typical fix: Replace the damaged TPMS sensor and register the new one. Sometimes only a rebuild kit with new gaskets is needed if the sensor itself is functional.
   Est. part cost: $40-$120

Rare But Worth Checking

• Faulty TPMS Control Unit / Receiver: If a new, known-good sensor has been properly registered but the C1709 code persists, or if multiple sensor codes (C1708, C1710, C1711) appear at once, the central TPMS receiver may be faulty. On the related G37 model, it is located behind the glove box. A user on MyG37.com reported fixing a multi-sensor failure by replacing the TPMS receiver module (P/N 40740-1NC2A for a 2013 model).
• Failing HVAC Blower Motor: → Shop HVAC Blower Motor A known issue on the related 2018 Nissan 370Z (TSB NTB19-062) is that a failing HVAC blower motor can generate enough RF interference to cause 'No Data' TPMS codes. If the TPMS light only appears when the fan is on high, this could be the cause. The fix is to replace the blower motor.

Diagnosis Steps

1. Verify the symptom: Confirm the TPMS light flashes for about a minute at startup and then stays on.
2. Scan the vehicle with an OBD-II scanner capable of reading 'C' (Chassis) codes to confirm C1709 is the active code.
3. Perform the RF Interference check: Unplug all aftermarket devices from 12V power outlets (phone chargers, dash cams, GPS units, etc.). Clear the code and drive the vehicle for 10-15 minutes at speeds above 25 MPH to see if the light returns.
4. If the light returns, use a dedicated TPMS diagnostic tool (like an Autel TS508 or similar) to attempt to activate and read the sensor at the front right wheel.
5. If the tool cannot get a reading from the sensor ('NO TPM FOUND' or similar message), the sensor has failed (likely a dead battery) and must be replaced.
6. If the tool *can* read the sensor's ID and data, but the car cannot, the issue may be with the TPMS registration or the central TPMS receiver module. Attempt a TPMS relearn procedure.
7. After replacing the sensor, the tire must be re-mounted and balanced. Then, use the TPMS tool to perform the relearn procedure, which registers the new sensor's ID to the vehicle's computer via the OBD-II port.

Parts You'll Likely Need

• Tire Pressure Monitoring System (TPMS) Sensor (OEM #40700-1LA0E) — This is the direct cause of the C1709 code when the internal battery dies or the unit is damaged. The entire sensor must be replaced as the battery is non-serviceable.
  Trusted brands: Infiniti (OEM), Denso, Schrader, Continental/VDO, Autel (programmable)
  OEM price range: $80-$115
  Aftermarket price range: $35-$80

Related Codes That Often Appear With This One

• C1708 — This is the code for the Front-Left sensor. Seeing both codes together often indicates that the sensor batteries are failing around the same time due to age.
• C1710 — This is the code for the Rear-Right sensor. Seeing multiple TPMS codes suggests a widespread battery failure issue or a problem with the central receiver.
• C1711 — This is the code for the Rear-Left sensor. When multiple sensors fail to report, it's cost-effective to replace all four at once to save on future labor costs.

Technical Service Bulletins (TSBs) & Recalls

• ITB13039A / NTB13-088: Discusses diagnosing the TPMS system, including radio frequency interference from accessories causing 'No Data' codes (C1708, C1709, C1710, C1711).
• NTB19-062: Specific to the 2018 370Z and GT-R, this TSB identifies a failing HVAC blower motor as a potential source of RF interference that can trigger TPMS codes.

Platform-Specific Known Issues

• This platform is documented by Infiniti in TSB ITB13039A as being susceptible to radio frequency interference from aftermarket electronics, which can cause 'No Data' TPMS codes like C1709.
• Owners on MyG37.com have documented DIY relearn procedures by grounding a specific pin near the OBD-II port, though this is complex and a TPMS tool is the recommended method.

Scan Tool Commands That Help

• Infiniti CONSULT: ID REGIST (in Work Support menu for Air Pressure Monitor) — This is the official dealer-level command used to register new TPMS sensor IDs to the Body Control Module (BCM) after a sensor has been replaced.

Wiring & Ground Locations

• TPMS Control Unit / Receiver — Located behind the glove box compartment. Access requires removing the glove box assembly.. This module receives the signals from all four tire sensors. If multiple 'No Data' codes (C1708, C1709, C1710, C1711) are present and sensors are known-good, this receiver is a likely point of failure. A faulty receiver will not get data from any sensor.
• TPMS Diagnostic Check Connector — A single-wire white connector, often taped to the main OBD-II port wiring harness under the driver's side dashboard.. This connector is the access point for the manual, tool-free TPMS relearn procedure. Grounding the pin in this connector multiple times puts the BCM into learning mode, allowing it to register new sensor IDs without a professional scan tool.
• Body Control Module (BCM) — In the passenger footwell, typically to the right, behind the kick panel trim.. The BCM is the central computer that processes the signals from the TPMS receiver and triggers the warning light on the dash. While a BCM failure is rare, a fault here could cause TPMS codes and other seemingly unrelated electrical issues.

Real Owner Repair Stories

• MyG37.com user 'milosz' (2013 Infiniti G37x) — TPMS light flashing then solid, with no specific tire pressure warning. OBD-II scan showed codes C1708, C1709, C1710, and C1711 ([NO DATA] for all four wheels).
  ❌ Tried (didn't work) Verifying all tire pressures were correct., Having a tire shop 'pair' the sensors, which worked for about a month before the light returned.
  ✅ What actually fixed it The user diagnosed that since all four sensors failed to report simultaneously, the issue was likely the central receiver, not the individual sensors. They replaced the 'TPMS Antenna' (the official name for the receiver module, P/N 40740-1NC2A) located behind the glove compartment. After replacing the module and clearing the codes, the TPMS light went away permanently.
