P0341 on 2021-2023 Jeep Gladiator: Cam Sensor Wiring and Performance Fixes

What's Unique About the 2021-2023 Jeep GLADIATOR

The Jeep Gladiator (JT platform), along with its Wrangler (JL) sibling, is uniquely prone to P0341 due to specific design and wiring layout issues. For the 3.0L EcoDiesel, Technical Service Bulletin #08-099-25 officially documents that the generator's (alternator's) main power wire is routed too close to the camshaft position sensor harness, causing electromagnetic interference (EMI) that disrupts the sensor signal. While the 3.6L gas engine is not covered by this TSB, owners frequently report the same code, with forum discussions pointing towards harness damage from proximity to hot exhaust components near the firewall. This makes P0341 on these platforms a much more likely wiring problem than a simple failed sensor.

Most Likely Causes

1. Camshaft Sensor Wiring Harness Interference/Damage 🔴 High Probability → Shop Engine Camshaft For 3.0L EcoDiesel: A known issue documented in TSB #08-099-25 where the generator wiring is routed too close to the cam sensor harness, causing electromagnetic interference. For 3.6L Pentastar: Forum reports indicate the harness is routed near the exhaust and firewall, where heat can cause chafing and signal issues.
   How to confirm: Visually inspect the wiring harness for the Bank 1 intake camshaft position sensor. On the 3.0L, check its proximity to the main alternator cable. On the 3.6L, inspect the harness section near the passenger-side firewall and exhaust for signs of heat damage, chafing, or melting.
   Typical fix: For 3.0L Diesel: Perform the repair outlined in TSB #08-099-25, which involves installing a twisted pair overlay harness (Mopar Part #68726700AA) and rerouting the generator wiring. For 3.6L: Repair any damaged sections of the wire and consider adding protective heat wrap (e.g., DEI sleeving) and routing it away from the exhaust.
   Est. part cost: $65-$95 for repair kits and supplies.
2. Faulty Camshaft Position Sensor 🟡 Medium Probability → Shop Engine Camshaft Position Sensor Sensors can fail from heat and vibration, but on this platform, it's a less common root cause than the wiring issue. Many owners replace the sensor only to have the code return.
   How to confirm: After verifying the wiring is good, swap the Bank 1 intake sensor with the Bank 2 intake sensor (they are identical). Clear the codes and drive. If the code changes to P0366 (Bank 2), the sensor is confirmed faulty.
   Typical fix: Replace the Bank 1 (passenger side) intake 🎬 Watch: Step-by-step guide for replacing the Bank 1 camshaft sensor. camshaft position sensor (Mopar #05149141AF).
   Est. part cost: $100-$150
3. Poor Electrical Connection at Sensor ⚪ Low Probability Vibration and heat cycles can cause connector pins to become loose over time.
   How to confirm: Inspect the sensor's electrical connector and the corresponding pins at the PCM for corrosion, moisture, or bent/loose pins. One owner reported their dealer found loose pins in the harness connector as the root cause.
   Typical fix: Clean the connectors with electrical contact cleaner and apply dielectric grease. If pins are loose, they may need to be re-tensioned or the connector pigtail replaced.
   Est. part cost: $5-$25

Rare But Worth Checking

• Timing System Issue: A stretched timing chain or a failing camshaft phaser can cause the camshaft's actual position to deviate from what the PCM expects, triggering a performance code. This is a more serious mechanical issue and would likely be accompanied by other codes or engine noises.
• Damaged Reluctor Wheel: The reluctor wheel (or tone ring) on the camshaft itself can be damaged or slip, preventing the sensor from getting a clean reading. This is uncommon and requires significant engine disassembly to inspect.
• Failed Rocker Arm / Damaged Cam Lobe: In a severe case reported by an owner, an unresolved P0341 issue was ultimately followed by a rocker arm failure that damaged a cam lobe, requiring major engine repair. This highlights the risk of ignoring the code.
• Faulty Powertrain Control Module (PCM): This is extremely rare and should only be considered after all other possibilities, including all wiring and mechanical checks, have been exhausted.

Diagnosis Steps

1. Read the trouble codes with an OBD-II scanner and confirm P0341 is present.
2. For 3.0L EcoDiesel models: Consult TSB #08-099-25. Thoroughly inspect the wiring harness for the Bank 1 (passenger side) intake camshaft position sensor, paying extremely close attention to its proximity to the generator (alternator) main power cable. If the TSB condition is found, perform the harness repair and rerouting procedure.
3. For 3.6L Pentastar models: Thoroughly inspect the same harness, focusing on the area near the passenger-side firewall and exhaust components for any signs of heat damage, chafing, or melting.
4. Inspect the sensor's electrical connector for corrosion, damage, or loose pins. Wiggle the connector while the engine is running (if safe) to see if it affects idle.
5. If wiring and connectors appear perfect, swap the Bank 1 intake camshaft sensor with the Bank 2 (driver's side) intake sensor. They are identical parts.
6. Clear the fault codes and drive the vehicle to see if the code returns. If code P0366 (Camshaft Position Sensor Performance - Bank 2) appears, the original sensor is faulty and should be replaced.
7. If code P0341 returns after the sensor swap, the problem lies within the wiring harness or the PCM's circuit, and a more in-depth electrical diagnosis is required.
8. If the code is intermittent and no fault is found, be aware of STAR Case #S2318000011, which notes the issue is under investigation by the manufacturer and may not have an immediate fix.

• STAR Case #S2318000011: Intermittent Fault Under Investigation: This internal document for dealers acknowledges P0341 on 2021 models. It notes that if no obvious wiring fault is found, the issue is considered intermittent and is under investigation by Stellantis. It advises dealers not to replace parts in these cases, which has led to some owners being told there is no current fix.
• Forum-Reported Harness Chafing (3.6L): Owners of Gladiators with the 3.6L Pentastar engine frequently report P0341 caused by the camshaft sensor wiring harness making contact with hot exhaust components near the passenger-side firewall. The heat can melt the insulation, causing intermittent shorts. The fix involves repairing the damaged wires and protecting the harness with high-temperature wire loom or sleeving.

Mechanic-Grade Diagnostic Values

• Camshaft Position Sensor 5V Supply Voltage (3.6L and 3.0L) — expected: 4.75 - 5.25 Volts DC. Failure: Voltage below 4.75V or above 5.25V indicates a problem with the PCM supply or a short in the harness.
• Camshaft Position Sensor Signal Voltage (3.6L) — expected: Switches between ~0V and ~5V. Failure: A signal that is stuck high, stuck low, or does not produce a clean square wave on an oscilloscope indicates a faulty sensor or reluctor wheel issue.
• Cam-Crank Sync Offset — expected: ±1°. Failure: An offset greater than ±3° suggests a mechanical timing issue, such as a stretched timing chain or jumped tooth, which a new sensor will not fix.

Scan Tool Commands That Help

• wiTECH (OEM) or advanced aftermarket scanner: Cam-Crank Sync Check — Use this function after verifying the sensor and wiring are good. It helps differentiate between an electrical fault and a more serious mechanical timing problem without engine disassembly.
• wiTECH (OEM) or advanced aftermarket scanner: Cam/Crank Relearn Procedure — After replacing a camshaft position sensor, some vehicles require this procedure for the PCM to learn the new sensor's specific signal characteristics. Failure to perform this may cause continued rough running or codes even with a good part.

Wiring & Ground Locations

• Engine Bay Grounds — Multiple ground studs are located in the engine bay, typically near the main battery on the passenger side fender.. A poor engine ground can introduce electrical noise and voltage drops, affecting the camshaft position sensor's reference voltage and potentially triggering a performance code.
• Passenger Kick Panel Grounds — Inside the cabin, behind the passenger-side kick panel, there are typically three ground points, one of which may be unused.. These grounds serve various body and module functions. While less likely to be the primary cause, a fault here can create difficult-to-diagnose electrical issues that could affect PCM operation.
• Frame Grounds — Several ground points are located along the frame rails, including behind the front passenger wheel and above the spare tire.. Ensuring the main chassis grounds are clean and tight is crucial for overall vehicle electrical health, which is the foundation for all sensor circuits.

Real Owner Repair Stories
