What it means: This Diagnostic Trouble Code (DTC) indicates a problem with the camshaft position sensor circuit in the bank 1 (or single sensor) of your engine. This sensor, often called a CMP sensor, plays a vital role in determining the timing of the engine's valves.
Possible causes:
* Faulty camshaft position sensor: The sensor itself might be malfunctioning.
* Open or shorted wiring: Damaged wiring to or from the sensor can disrupt its function.
* Corrosion or poor connection: Corrosion or a loose connection at the sensor or wiring connector can interrupt the signal.
* Damaged engine harness: Damage to the engine harness, possibly caused by heat or wear, can affect the sensor circuit.
* Faulty engine control module (ECM): The ECM, which interprets the sensor's signals, might be malfunctioning.
Symptoms you might experience:
* Check Engine Light: The most common symptom, indicating a problem.
* Engine misfire: The timing is disrupted, leading to uneven engine operation.
* Rough idle: Similar to misfires, an irregular idle can occur.
* Reduced engine power: The engine might struggle to produce its normal power output.
* Difficulty starting: The engine might struggle to start, or fail to start altogether.
Troubleshooting steps:
1. Inspect the sensor: Visually check the camshaft position sensor for any damage or signs of corrosion.
2. Check the wiring: Inspect the wiring for any breaks, cuts, or signs of wear. Ensure all connections are tight and clean.
3. Test the sensor: Use a multimeter to test the sensor's resistance and voltage output. This requires technical knowledge and proper equipment.
4. Scan for other codes: Additional codes might provide further clues about the underlying issue.
5. Professional diagnosis: If you're unable to identify the cause, it's best to have a qualified mechanic diagnose the problem.
Important Note: The location and specific troubleshooting procedures can vary depending on the make and model of your vehicle. Refer to your owner's manual or consult with a certified mechanic for accurate troubleshooting instructions.
