THROTTLE POSITION SENSOR (TPS)
General
The throttle position sensor (TPS) is potentiometer that sends signal to the MPEM which is proportional to the throttle shaft angleOn the DI system, two sensors are used for redundancy purposesThe MPEM compares the signals from both sensors and determines if there is an error and uses the most appropriate sensor to operate the system
NOTE: In this particular case, by comparing the signals from both sensors, the MPEM will generate fault code when the TPS is malfunctioning due to specific "spots"To isolate the faulty TPS, disconnect one and test the other
Voltage Test Both TPS
