Variable Valve Timing Control Advance Malfunction
Table of contents
P1009 ACURA Possible Causes
- Engine oil level
- Dirty engine oil
- Check VTC Strainer for blockage
- Faulty VTC Oil Control Solenoid or circuit
- Faulty VTC Actuator
- Engine mechanical problems
How do I fix code P1009 ACURA?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- An stretched timing chain or damaged tensioner can also caused triggered the P1009 code. Before replacing timing chain or tensioner, check engine oil level and condition. Replaced engine oil and filter with factory recommend oil weight if necessary.
Cost of diagnosing the P1009 ACURA code
The cost of diagnosing the P1009 ACURA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1009 ACURA Description
The variable valve timing control (VTC) system controls the phase of the intake camshaft. It uses oil pressure to operate the VTC actuator so the valve timing is optimized depending on driving conditions. The engine control module (ECM)/Powertrain control module (PCM) monitors the phase control command and the actual timing of the camshaft by using camshaft position
(CMP) sensor A. If an over-advanced camshaft phase (compared to the directed value) continues or when the camshaft phase is otherwise abnormal, a malfunction is detected and a DTC is stored.
