This summary uses the existing diagnostic information shown in full below.
This code means that a sensor that helps control a part of the engine called the camshaft is not working properly. It's like a helper that tells the engine how to move, but it's not doing its job right.
The P2C1C code indicates a problem with the electrical circuit of the camshaft profile actuator position sensor C on bank 1 of the engine. The sensor is reading a voltage that is too low.
The camshaft profile actuator position sensor monitors the position and movement of the camshaft to optimize engine performance. A 'circuit low' condition means that the sensor is reporting a voltage below the expected range, which can affect engine timing and performance.
• Check Engine Light is on
• Reduced engine performance
• Engine misfires or runs rough
• Faulty camshaft profile actuator position sensor
• Wiring issues such as shorts or open circuits
• Poor electrical connections
Camshaft: A shaft in the engine that controls the opening and closing of the valves.
Actuator: A device that causes a machine or other device to operate.
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connections to the sensor
• Test the sensor's voltage and resistance
• Replace the faulty camshaft position sensor
• Repair or replace damaged wiring
• Ensure all electrical connections are secure
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular maintenance and inspections
• Keep electrical connections clean and secure
• Use high-quality replacement parts
Sensor Issue
• Do not ignore the Check Engine Light
• Consult a professional mechanic if unsure
• Avoid driving the vehicle if performance is severely affected
Check with the vehicle manufacturer for warranty coverage on engine sensors.
This code has been associated with camshaft sensor issues in various vehicle models, often due to wear and tear or electrical faults.
Moderate – While the vehicle may still be drivable, it can lead to decreased performance and potential damage if not addressed.
Driving with a faulty camshaft sensor can lead to engine performance issues, which may affect vehicle safety.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The camshaft profile actuator position sensor is located on the engine, typically near the camshaft itself.
Q: Can I drive with a P2C1C code?
A: It's possible to drive, but it's not recommended as it can affect engine performance.
Q: How can I reset the Check Engine Light?
A: You can reset it with an OBD-II scanner, but it's important to fix the underlying issue first.

Fitment Required · Vehicle-fitment part
Commonly relevant for misfire, ignition-efficiency, and some drivability-related repairs.
Misfire and ignition-related faults commonly involve spark plugs as part of the repair path.
Check the correct plug type, gap, and engine application for your vehicle.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
