- The TPS signal is important for the control of the automatic transaxle. Shift shock and other trouble may occur if the sensor is faulty.
- If the idle condition or acceleration is abnormal, check the TPS connector. (When the TPS connector is not connected properly, the current data on HI-SCAN can show that the idle state remains off, although the accelerator pedal is released. This results in the improper idle or acceleration.)
