The position sensor C of camshaft profile actuator on the exhaust side of bank 1 reports a circuit high condition. Cam profile selection feedback cannot be measured reliably.
Medium severity. Can I keep driving?Drive little and gently. If you hear timing chain noise or the oil light comes on, shut off the engine.
Bank 1 is the side of the engine with cylinder 1. Inline engines only have this bank.
Symptoms
- Check engine light on
- Power loss especially in mid-rpm range
- Possible rough idle or stalling
- Increased fuel consumption
Most likely causes
- Signal wire shorted to B+
- Open position sensor
- Connector pins corroded - high contact resistance
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It can trigger limp mode.
- It affects emissions.
What each character of P2C1D means
- P: Powertrain: engine and transmission
- 2: Generic code: same on every make
- C: Subsystem depends on the code range
- 1D: Specific fault in that system
