Connect the scan tool to the data link connector(DLC)

Connect the probe of scan tool to the RPS terminal 2 and start the engine

Check the RPS waveform when depressing the accelerator pedal fully one time.

IS THERE THE SIGNAL WAVEFORM PRORERLY ?

YES

NO

a.

Recheck the RPS

b.

Recheck open or short in the wire between the RPS terminal 2 and the ECM terminal 10/C230-2.

c.

Go to step 5

WAVEFORM ANALYSIS

This test should be inspected after depressing the HOLD mode from run after the sudden acceleration. The waveform pattern become increasing upward rapidly when the engien speed increases. If the waveform pattern becomes distorted after the sudden acceleration, replace the RPS

MONITORING FOR PENDING DTC SET ?

YES

NO
