Component Testing
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the AT harness connector at the transmission.
- Install the J 44152 to the 20-way connector at the transmission. See Special Tools .
- Test for 3106-3923 ohms between the signal circuit terminal L and the low reference circuit terminal M of the transmission.
- If not within the specified range, test the circuits for a short to ground or an open/high resistance. If a circuit is shorted or open replace the internal transmission wiring harness assembly, if the circuits test normal, replace the TFT sensor.
- Test for infinite resistance between each terminal and the transmission housing/case.
- If not the specified value, test the circuits for a short to ground or an open/high resistance. If a circuit is shorted replace the internal transmission wiring harness assembly, if the circuits test normal, replace the TFT sensor.
