Sensor And Actuator Circuit Resistance Tests: Notes
CAUTION:
To avoid damage to the connector terminals, ensure that the transmission control module is not tilted or twisted during removal.
To access the transmission harness connector, remove the transmission control module.

CAUTION:
Take care to avoid damage when probing connectors.
A DTC will set in the transmission control module when an automatic transmission sensor or actuator circuit fault is detected. The relevant circuit resistance value(s) can be measured at the automatic transmission harness connector after removing the transmission control module.

- Measure the resistance between the terminals of the suspect circuit and compare to the resistance value listed below.
- Measure the resistance between the terminals of the suspect circuit and the transmission casing; the measured value should be infinitely high (open circuit) - Not applicable to shift solenoid 1 and shift solenoid 2.
- Measure the resistance between the terminals of the suspect circuit and all other terminals; the measured value should be infinitely high (open circuit).
If a circuit resistance is outside of specification, check the transmission internal wiring harness before condemning a sensor or actuator.
