Throttle Position Sensor: Tercel
- Ensure ignition is off. Disconnect electrical connector from TP sensor on throttle body. Note terminal identification. See Figure. On A/T models, disconnect throttle cable from linkage before checking TP sensor.
- On all models, use ohmmeter to check resistance between specified terminals in relation to throttle position. See TP SENSOR RESISTANCE SPECIFICATIONS (TERCEL - 1.5L) table. Replace components as necessary if resistance is not within specification.
