Checking The Component And Wiring

Check the connector for the transmission control module (TCM). Check for contact resistance. Check for oxidation.
Check that the transmission output speed sensor is correctly installed and that there is no damage to the speed sensor.

Check the power supply cable between transmission control module (TCM) terminal #B2 (#A52) and the transmission output speed sensor. Check for a short-circuit to supply voltage. Check for a short-circuit to ground. Check for an open-circuit.

Check the signal cable between transmission control module (TCM) terminal #B1 (#A51) and the transmission output speed sensor. Check for a short-circuit to supply voltage. Check for a short-circuit to ground. Check for an open-circuit

HINT: This diagnostic trouble code (DTC) can be caused by a fault in the transmission output speed sensor
