Circuit/System Verification
1. Engine running, DTC P0712 or P0713 should not set.
2. If the vehicle passes the Circuit/System Verification Test, then operate the vehicle within the conditions for running the DTC. You may also
operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the TFT sensor.
2. Ignition OFF, test for less than 5 ohms of resistance between the low reference circuit terminal A and ground.
瀚慖f greater than 5 ohms, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace
the ECM.
3. Ignition ON, using a scan tool verify that the TFT sensor parameter is at -40掳C (-40掳F).
瀚慖f greater than -40掳C (-40掳F), test the signal circuit terminal B for a short to ground. If the circuit tests normal, replace the ECM.
Note: If the signal circuit of the TFT sensor is shorted to voltage the TFT sensor may be damaged.
4. Install a 3-amp fused jumper wire between the signal circuit terminal B and the low reference circuit terminal A. Verify the TFT sensor
parameter is greater than 128掳C (262掳F).
瀚慖f less than 128掳C (262掳F), test the signal circuit of the TFT sensor for a short to voltage or an open/high resistance. If the circuit test
normal, replace the ECM.
5. If all circuits test normal, test or replace the TFT sensor.
