INSPECTION PROCEDURE

HINT:
- Perform troubleshooting of DTC P0335 first. If no trouble is found, troubleshoot the engine mechanical system.
- Read freeze frame data using the hand-held tester or the OBD II scan tool, as freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.
