1.

IG Key : ON

2.

Actual value for evaluation

Engine warm up to approx. 80℃(176℉), engine idling

3.

Check items with the scantool

Accelerator position sensor current data

4.

Specification

1)

At idle set value : 0.2 ~ 0.5 V

2)

Full acceleration : 1.6 ~ 2.5 V

☞ CURRENT DATA

During the acceleration, the APS 1 and APS 2 output voltage increase. During the deceleration, the APS 1 and the APS 2 output voltage decrease. The APS 1 and APS 2 signal should be compared with the Mass Air Flow meter Sensor (MAFS) signal. Check whether APS 1, APS 2 and MAFS signals are increased at the same time when depressing the accel pedal

5.

IS APS SIGNAL DISPLAYED PROPERLY ?

YES

a.

Fault is intermittent caused by poor contact in the sensor’s and/or ECM’s connector or was repaired and ECM memory was not cleared.

b.

Check for intermittent fault by observing the data parameter for a sudden change while wiggling the wiring and tapping lightly on the suspect component.

caution

Be careful not to damage wires or components during the test.

c.

Repair as necessary and go to " Verification of Vehicle Repair " procedure

NO

a.

Go to " W/Harness Inspection " procedure.
