OPERATION
The Throttle Position Sensor (TPS) contains two actual value potentiometers for detecting the position of the throttle
valve. The second potentiometer is designed to form a reference value. The system will switch over to the second
potentiometer if the first one fails. The TPS cannot be serviced separately. If the TPS fails, the Throttle Body must
be replaced. Refer to the Throttle Body service procedures. (Refer to 14 - FUEL SYSTEM/FUEL INJECTION/
THROTTLE BODY - REMOVAL).
