Code 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 the 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 Diagnostic Trouble Code (DTC) is stored.

I added a can of "Restore" engine oil additive to my 06 Accord 4cyl last night. On my way to work the light came on. This code was indicated when using an OBD reader. Can't say for certain, but I think the additive is what caused the light. After scanning, the light remained. I went to another auto parts store to ask what they thought, however when I restarted my car at the second store, the engine light no longer apeared. I think the oil additive caused it.
