Start by checking 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.
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.
The cost to diagnose the P1009 ACURA code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
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.
