Inspection Procedure

HINT: 

• If DTC P0013 is displayed, check the exhaust camshaft circuit for the right bank VVT system (bank 1).
• If DTC P0023 is displayed, check the exhaust camshaft circuit for the left bank VVT system (bank 2).
• Bank 1 refers to the bank that includes the No. 1 cylinder*.

  *: The No. 1 cylinder is the cylinder which is farthest from transmission.

• Bank 2 refers to the bank that does not include the No. 1 cylinder.
• Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
