Vehicle Speed Sensor
WARNING: This page is about a different car, the 2002 Toyota ECHO, 2002 Toyota Celica, 2001 Toyota ECHO, and 2001 Toyota Celica. However, it is still accessible from the selected car via links, so may be relevant.
- Remove speed sensor from transaxle. Using a DVOM, measure resistance between sensor terminals. Resistance should be 560-680 ohms. If resistance is not as specified, replace sensor. If resistance is as specified, check and repair circuits between sensor and ECM.
- Check voltage between sensor terminals when a magnet is put close to tip of speed sensor. See Fig 1. If a low intermittent voltage is generated, sensor is okay. If no voltage is generated, replace speed sensor.
