P1009 Possible Causes
- Engine oil level
- Dirty engine oil
- Check VTC filter for blockage
- Faulty VTC oil control solenoid or circuit
- Defective VTC actuator
- Engine mechanical problems
How is P1009 Code Repaired?
Start by checking the “Possible Causes” listed above. Visually inspect related wiring harnesses and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
Possible Symptoms
Engine light on (or service engine soon warning light)
P1009 Meaning
The Variable Valve Timing Control (VTC) system controls the phase of the intake camshaft. It uses oil pressure to operate the VTC actuator so that valve timing is optimized according to driving conditions. The Engine Control Module (ECM) / Powertrain Control Module (PCM) monitors the phase control command and actual camshaft timing using the Camshaft Position (CMP) sensor A. If an excessively advanced camshaft phase (compared to the commanded value) continues or when the camshaft phase is otherwise abnormal, a malfunction is detected and a DTC is recorded.
