How much does this it cost to repair this code 1009 on honda 2006 crv

DTC P1009 = Variable Valve Timing Control (VTC) Advance Malfunction

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 ECM 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 DTC is stored in the ECM.

It can be an oil pressure issue--ensure the oil level is correct and that there is no sludging. Sludging can be disastrous on VTEC engines. Ensure the proper oil, viscosity, and filter are being used. Another common problem are VTEC solenoids going bad, which is a job best left for the dealer to repair.

For VTEC engines, I only recommend full-synthetic engine oil (e.g. Mobil 1 or Pennzoil Platinum SAE 5W-20). Therefore, I would start by changing the oil and filter, using synthetic oil and a premium Mobil 1 filter ($50). Do this every 6,000 miles or 6 months, whichever comes first. This may emulsify any sludge and the Check Engine Light may go out on its own; if not, use a code reader to try and erase the code. If the problem persists, have Honda replace the VTEC solenoid, which will likely cost around $200.
