Inspection Procedure

HINT:

• Read freeze frame data using a hand-held tester or OBD II scan tool. Freeze frame data record the engine condition when malfunctions are detected. 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.
• If any of DTCs P0115, P0116 and P0125 are output simultaneously, the engine coolant temperature sensor circuit may be open or short. Perform troubleshooting of DTC P0115 first.

Replace engine coolant temperature sensor.
