Component Inspection
■ Check APS
1.

IG "OFF" and install a GDS.

2.

Connect probe to APS1 and APS2 to check signal waveform by using oscilloscope function.

3.

Measure signal waveform of APS by pressing and depressing accellerator pedal.

Specification : Signal waveform will be displayed as follows.

Pedal Position

Output Voltage(V) [Vref = 5.0V]

APS1

APS2

C.T

0.7 ~ 0.8V

0.29 ~ 0.46V

W.O.T

3.85 ~ 4.35V

1.93 ~ 2.18V

4.

Is the measured signal waveform O.K ?

▶ Substitute with a known - good ECM and check for proper operation. If the problem is corrected, replace ECM and go to "Verification of Vehicle Repair" procedure.

▶ Substitute with a known-good APS and check for proper operation. If the problem is corrected,replace APS and then go to "Verification of Vehicle Repair" procedure.
