Inspection Procedure

HINT:

• If DTCs "P0115, P0116, P0117, P0118 and P0125" are output simultaneously, the engine coolant temperature sensor circuit may be open or short. Perform the troubleshooting for DTCs "P0115, P0117 or P0118" first.
• Read freeze frame data using the hand-held tester or the OBDII scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful to determine 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 the malfunction occurred.

Replace engine coolant temperature sensor.
