Component Inspection

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













Fig. 1) Normal waveform of TPS1 & TPS2 with no accel pedal depressed under IG ON condition
Fig. 2) Normal waveform of TPS1 & TPS2 with accel pedal depressed under IG ON condition




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 and keep this condition until the main relay is turned off. (It will take 10 sec.)
C. Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
