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).
