2012 RAV4 base, V6, 79,000 miles; Coming home today and 3 lights appeared while on the highway-
Trac off, 4WD and check engine light.

That consists of a few different components but the P0015 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. Bank #1 is the side of the engine that contains cylinder #1. The "B" camshaft shall be either the "exhaust," "right," or "rear" camshaft. Left/Right and Front/Rear are determined as if viewed from the driver's seating position.
A P0015 DTC trouble code may be caused by one or more of the following:
  • Incorrect camshaft timing
  • Wiring problems (harness/wiring) in intake timing control valve control solenoid system
  • Continuous oil flow to VCT piston chamber
  • Failed timing valve control solenoid (stuck open)
The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

thank you for your replies JuneBug and grmuller, I cleared the code and it did not return on my 50 mile drive to work this morning so it may be intermittent, I expect it to return at some point though.


From what I've read its looking like the passenger side, rear one against the fire wall. I did spark plugs last fall, an adventure in itself, so maybe I'll pickup the correct OCV at some point and another set of plugs since I've read the intake needs to come off again. Will try to get it done before winter comes anyway.
