Code P0342 Description
The P0342 diagnostic trouble code (DTC) indicates a problem with the Camshaft Position Sensor 'A' Circuit. This sensor plays a crucial role in the engine management system by providing information on the camshaft's position to the engine control module (ECM). The ECM uses this data to determine the optimal timing for fuel injection and ignition.
Common Causes of P0342
- Faulty Camshaft Position Sensor: The sensor itself may be defective and not sending accurate signals to the ECM.
- Wiring issues: Damaged or corroded wiring connections can disrupt the signal from the sensor to the ECM.
- Poor electrical connection: Loose or poor electrical connections can lead to a low voltage input.
- Timing chain or belt issues: Problems with the timing chain or belt can affect the camshaft's position, triggering the code.
- ECM malfunction: A malfunctioning ECM may not be able to interpret the sensor's signals correctly.
Symptoms of P0342
- Rough idle or stalling: The engine may run erratically or stall at idle due to incorrect timing.
- Misfires: The engine may misfire under load or acceleration, causing a loss of power.
- Poor fuel economy: Incorrect timing can lead to inefficient combustion, reducing fuel efficiency.
- Check Engine Light: The P0342 DTC will trigger the Check Engine Light on the dashboard.
- Engine cranking but not starting: In severe cases, the engine may fail to start due to the timing issue.
How to Fix P0342
- Diagnose the issue: Use a scan tool to read the DTC and check the camshaft position sensor's voltage output.
- Inspect wiring and connections: Check the wiring harness for any damage or corrosion. Repair or replace as needed.
- Replace the camshaft position sensor: If the sensor is faulty, replace it with a new one following the manufacturer's guidelines.
- Clear the DTC: Use a scan tool to clear the DTC after replacing the sensor and ensure the issue is resolved.
- Test drive: Test drive the vehicle to confirm that the symptoms are no longer present and the engine runs smoothly.
Cost to Fix P0342
The cost of repairing a P0342 code can vary depending on the make and model of the vehicle, as well as the location and labor rates of the repair shop. Typically, the cost of a new camshaft position sensor ranges from $50 to $200, depending on the brand and quality. Labor costs can add another $100 to $200, bringing the total repair cost to around $150 to $400. It is advisable to check with local auto repair shops for accurate pricing based on your specific vehicle and location.

2002 LS1, hard to start and backfires when starting. I replaced cam sensor and still have same problem and code. 102 and 342. I assumed backfire would trigger MAF light and have not replaced MAF...yet. Input?

You may have to replaced the Mass Air Flow (MAF), but before you replaced any other part check the following:
- Air filter (replaced if necessary)
- Any object blocking the air through the air filter and MAF
- The air duct after the air filter housing
- Intake hoses after the MAF -

I have Chevrolet optra 2011 the Problem was code p0342
Camshaft Position Sensor 'A' Circuit Low Input
I did not find any of these options is the real reason for this cod !- Faulty Camshaft Position Sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty starter motor
- Starting system circuit
- Dead (Weak) batteryThe reason for this problem.
After work, effort and found CAM shaft rollers were inverted in the sense that the last reel input air was in place output the exhaust and there is a difference between the rollers and CAM shaft because Sensor works only on reel exhaust appears to me that when the testing Sensor that works well.

I have 2004 VW Jetta BBW engine. 147k miles. Right now my car will not travel over 3,000RPM. I went to the dealership and they said it was a Camshaft position sensor. After I replaced it the car will still not travel over the 3,000 RPM. I scanned it and the code was > P0342 CAMSHAFT POSITION SENSOR A- BANK 1 CIRCUIT LOW INPUT. What I should do now?
