CAUTION / NOTICE / HINT
If DTC P0115, P0117 or P0118 is output simultaneously with DTC P0116, the engine coolant temperature sensor may have an open or a short circuit. Troubleshoot those DTCs first.
Read freeze frame data using the GTS. 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.
CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0116)
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
Read the DTCs.
|DTC P0116 is output||A|
|DTC P0116 and other DTCs are output||B|
If any DTCs other than P0116 are output, troubleshoot those DTCs first.
