Code P0342 Chrysler Description
The P0342 diagnostic trouble code (DTC) refers to a malfunction in the camshaft position sensor circuit, specifically indicating that the input signal from the sensor is lower than the specified range. This sensor plays a crucial role in detecting the position of the camshaft in relation to the crankshaft, providing essential data for proper fuel injection timing and ignition system operation. When the sensor fails to provide accurate signals, it can lead to incorrect fuel delivery, misfires, and overall poor engine performance.
Common Causes of P0342 Chrysler
- Faulty camshaft position sensor
- Damaged or frayed sensor wiring
- Poor electrical connection or corroded terminals
- Issues with the sensor's reluctor ring or wheel
- ECU (engine control unit) malfunction
Symptoms of P0342 Chrysler
- Engine misfires or rough idling
- Decreased fuel efficiency
- Engine stalling or difficulty starting
- Illumination of the check engine light
- Loss of power or acceleration
How to Fix P0342 Chrysler
- Begin by diagnosing the exact cause of the low input signal, using a scan tool to retrieve and analyze the DTC.
- Inspect the camshaft position sensor and its wiring harness for any visible damage or corrosion, replacing or repairing as necessary.
- Test the sensor's electrical connections and grounds to ensure proper connectivity.
- Reset the DTC and clear the engine's fault codes before test driving the vehicle to verify that the issue has been resolved.
- If the problem persists, consider consulting a professional mechanic for further diagnosis and potential ECU replacement.
Cost to Fix P0342 Chrysler

Frequently Asked Questions about P0342 Chrysler Code
1. What does the OBDII code P0342 mean on a Chrysler vehicle?
P0342 indicates that the Camshaft Position Sensor Circuit has a low input signal, which means the sensor is reporting a voltage lower than the expected range to the powertrain control module (PCM).
2. What are the common symptoms of a P0342 code in a Chrysler?
Symptoms may include engine stalling, rough idling, hard starting, poor acceleration, reduced fuel efficiency, and an illuminated check engine light.
3. What causes the P0342 code to be triggered in a Chrysler?
Common causes include a failed camshaft position sensor, damaged wiring or connectors in the camshaft sensor circuit, a faulty PCM, or a weak battery or charging system issue.
4. Can a weak battery cause the P0342 code in a Chrysler?
Yes, a weak or failing battery can cause low voltage that affects the camshaft position sensor circuit, leading to the P0342 code.
5. How do I diagnose the P0342 code on my Chrysler?
Start by checking the camshaft position sensor and its wiring for damage, test the battery voltage, inspect the connectors for corrosion, and use a multimeter to measure the sensor’s output voltage.
6. Is it safe to drive with the P0342 code on a Chrysler?
Driving with a P0342 code is not recommended, as it can lead to engine stalling or failure to start, which could create unsafe driving conditions.
7. How do you fix a P0342 code on a Chrysler?
Repairs may include replacing the camshaft position sensor, repairing or replacing damaged wiring or connectors, charging or replacing the battery, or reprogramming/updating the PCM if necessary.
8. How much does it cost to repair the P0342 code on a Chrysler?
The cost can vary, but replacing a camshaft position sensor typically ranges between $100 and $300, depending on parts and labor costs.
9. Can the P0342 code be caused by a timing issue in a Chrysler?
Yes, improper timing, such as a misaligned timing belt or chain, can affect the signal from the camshaft position sensor and trigger the P0342 code.
10. Will clearing the P0342 code fix the issue in a Chrysler?
Clearing the code without addressing the underlying problem will not fix the issue, and the code is likely to return until the root cause is resolved.
