Code P0015 Toyota Description

The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.
The camshaft timing oil control valve assembly is a solenoid valve and switches the engine oil line. The valve moves when the Engine Control Module (ECM) applies 12 V to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.
The ECM optimizes the exhaust valve timing using the Variable Valve Timing (VVT) system to control the exhaust camshaft. The VVT system includes the ECM, the camshaft timing oil control valve assembly and the VVT controller (camshaft timing exhaust gear assembly). The ECM sends a target duty-cycle control signal to the camshaft timing oil control valve assembly. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the exhaust camshaft.

  • help fault code p0015 and p0017 on toyota camry 2008 2gr engine

  • What type of help do you need? You could start by changing the engine oil.

  • Can u still drive the car

  • I have a Toyota Camry 2007 (6 cylinders) and yesterday I got the check engine and VSC lights on after filling the gas. I tightened the fuel cap and even replaced it with a new one (after reading many google posts). I am getting P0015, P0017 and P0300. The dealer did not suggest anything except to change engine oil when I received the same code twice few months ago. Now, he wants to 'start with 1 oil control valves with spark plugs' repair which could cost around $1200'. I drove to AutoZone to get the second opinion. The sales person/technician ran the code check and received the same set of codes. But he suggested to replace all 6 spark plugs and ignition coil'. Not sure which suggestion to go with. Car runs ok. But, at the traffic light, jumps a little (once in a while)' It could be related to mis-firing..not sure..Any suggestion?

  • what was the outcome?

  • I have just replaced both lower control arms on my 2013 Toyota sienna le. Now van starts but stall's right away. Where do I start the fix this.

    • Replacing lower control arms normally would not cause a P0015 directly, so I would start by looking for something that may have been disturbed during the repair rather than assuming the timing suddenly failed.

      Since the van starts and then stalls immediately, first check the basics:

      • Make sure the battery is fully charged and terminals are tight
      • Double-check that no connectors or grounds were left loose near the engine bay or frame during the suspension work
      • Inspect the intake tube between the air box and throttle body — if it’s loose or cracked, the engine can start and stall
      • Check for vacuum hoses accidentally pulled loose
      • Scan again and see if P0015 is the only code returning

      Now specifically for P0015 on the 2013 Sienna:
      That code means the exhaust cam timing on Bank 1 is staying too far retarded. Common causes are:

      • Dirty or low engine oil
      • Faulty VVT oil control valve (OCV)
      • Oil flow restriction to the VVT system
      • Timing chain stretch (less common)

      A sticking VVT solenoid can absolutely cause stalling at idle.

      One thing I’d try:
      Remove and inspect the Bank 1 exhaust VVT oil control valve connector and make sure it’s fully seated. Sometimes a connector gets bumped during unrelated repairs.

      If the van ran perfectly before the control arm job, I’d strongly suspect:
      • a disconnected intake/vacuum issue,
      • weak battery voltage after the repair,
      • or a connector/ground disturbed during the work.

      I would not jump straight to timing chain replacement unless the code was already present before the suspension work.
