Component Inspection

Check TPS
1. IG "ON"
2. Monitor signal waveform and output voltage of TPS by stepping on and off the accelerator pedal in GDS
Specification :













Fig. 1) Normal waveform of TPS1 & TPS2 with acceleration pedal not depressed with IG "ON"
Fig. 2) Normal waveform of TPS1 & TPS2 with acceleration pedal depressed with IG "ON"




3. Is the measured signal waveform O.K?






** Procedure of ETS Initialization
A. Erase the trouble codes on PCM
B. Turn the ignition key "OFF" until the main relay turns "OFF". (It will take about 10 sec.)
C. Turn ignition key "ON" for more than 1 second to record the throttle motor position in the EEPROM
