This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in the car's engine is detecting a problem with a part that controls how the engine's camshaft moves. It's like a sensor telling you that something isn't right with a part that helps the engine run smoothly.
The P2C10 code is triggered when the Engine Control Module (ECM) detects a high voltage condition in the camshaft profile actuator position sensor C circuit on bank 1.
This diagnostic trouble code (DTC) indicates that the camshaft profile actuator position sensor C circuit on bank 1 is reporting a voltage level that is higher than expected. This sensor is responsible for monitoring the position of the camshaft actuator, which adjusts the camshaft's position to optimize engine performance.
• Check Engine Light is on
• Poor engine performance
• Rough idling
• Faulty camshaft profile actuator position sensor
• Wiring issues in the sensor circuit
• ECM malfunction
Camshaft: A shaft in the engine that controls the opening and closing of the valves.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the camshaft profile actuator position sensor for proper operation.
• Replace the camshaft profile actuator position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular maintenance and inspections
• Promptly address any Check Engine Light warnings
• Ensure proper oil levels and quality
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you're unsure.
• Regularly check and maintain your vehicle's sensors.
Check with your vehicle's manufacturer for specific warranty coverage on engine components.
This code has been associated with issues in vehicles utilizing advanced camshaft timing systems, especially in models with variable valve timing.
Moderate – While the vehicle may still be drivable, ignoring the issue can lead to more severe engine problems.
Driving with a malfunctioning camshaft actuator sensor can lead to increased emissions and potential engine damage.
• Engine running at operating temperature
• Vehicle stationary or at idle
The camshaft profile actuator position sensor is typically located near the top of the engine, close to the camshaft.
Q: Can I drive with a P2C10 code?
A: It's not recommended to drive for extended periods with this code as it can lead to further engine issues.
Q: How can I prevent this code from appearing?
A: Regular maintenance and ensuring that engine components are in good working order can help prevent this code.
