Throttle Position Sensor: Tercel

  1. 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.
  2. 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.
