What it means
A Camshaft Position Actuator Position Sensor C Circuit (Bank 1): an electrical fault is present in the circuit. This relates to engine timing; a fault can cause rough running, a no-start, or timing errors.
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
The Bank 1 camshaft position actuator position sensor C reports the position of the actuator used to adjust camshaft timing. The ECM monitors this sensor circuit, and this code sets when it detects an electrical fault in the Bank 1 sensor C circuit.
Common causes
Most likely first.
- Camshaft position actuator position sensor C fault
- Open, shorted, or damaged wiring or connector
- Camshaft actuator or timing mechanism fault
- Engine control module circuit fault
Symptoms
- Check engine light on
- Power loss especially in mid-rpm range
- Possible rough idle or stalling
- Increased fuel consumption
How to diagnose it
- Save freeze-frame data and scan for related camshaft timing or actuator codes to identify when the Bank 1 sensor C fault occurred.
- Locate the Bank 1 camshaft actuator position sensor C using vehicle service information and inspect its connector and wiring for damage, oil, or loose terminals.
- Check the sensor circuit for opens, shorts, and poor terminal contact using the wiring diagram and manufacturer's procedure.
- Verify sensor supply and ground, then check the sensor output while commanding or observing camshaft actuator movement if supported.
- If the circuit and sensor pass, inspect the Bank 1 camshaft actuator and timing mechanism for binding or incorrect movement.
Common fixes
- Reconnect or clean the Bank 1 sensor C connector if contact is poor.
- Repair open, shorted, or damaged wiring in the Bank 1 sensor C circuit.
- Replace the Bank 1 camshaft actuator position sensor C if it fails testing.
- Repair a confirmed Bank 1 actuator or timing mechanism fault.
Can I keep driving?
A short, gentle trip may be possible if the engine runs normally, but avoid high loads and arrange diagnosis soon. Stop if it stalls, runs very roughly, or will not maintain power, since incorrect camshaft timing can affect engine operation.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
