Countershaft Sensor: Service and Repair



NOTE: The following paragraph is an excerpt from Honda Service News, Dated November 2001

The '00-01 Odyssey with the navigation system has a differential driven vehicle speed pulse (VSP) sensor. Its signal is used to calculate vehicle speed for the climate control system and the navigation system. The '99 Odyssey, the '00-01 Odyssey without the navigation system, and the '98-02 Accord V6 use a vehicle speed signal that the FCM/PCM calculates from countershaft speed. This signal is shared by all systems that need a vehicle speed input.

Countershaft Speed Sensor Replacement

1. Disconnect the connectors from the mainshaft and countershaft speed sensors.





2. Remove the bolt securing the mainshaft speed sensor, then remove the mainshaft speed sensor from the end cover.





3. Remove the bolt securing the countershaft speed sensor, then remove the countershaft speed sensor (A) and the washer (B) from the transmission housing.
4. Replace the O-rings (C) with new ones before installing the sensors.
5. Install the mainshaft speed sensor, then connect the connector.
6. Install the countershaft speed sensor with the washer, then connect the connector.
