Revolution Sensor
- Disconnect A/T revolution sensor connector. See Figure. Measure resistance between terminals No. 2 and No. 3 on revolution sensor harness connector (transmission side). Resistance should be 500-650 ohms. If resistance is not as specified, replace sensor. See Figure.
- Backprobe TCM harness connector using voltmeter set on AC scale. Measure voltage between ground and terminal No. 25. See Figure. Voltage should rise gradually relative to vehicle speed. At zero MPH, voltage should not be present. If voltage does not rise when vehicle is driven, repair circuit as necessary.
