HINT: If diagnostic trouble code for gear position sensor is stored in transmission control module (TCM), then troubleshoot this diagnostic trouble code first.

- Check transmission control module (TCM) connector for contact resistance and oxidation.

Check the signal cable for open circuit, short-circuit to voltage and short-circuit to ground.

Measure between engine control module (ECM) #B15 (#C15) and transmission control module (TCM) #5.

Remedy as necessary.

HINT: Read off the gear position sensor's signals by clicking on the symbol for VCT2000.
