Check specified value for Throttle Position (TP) sensor -G79- at idle stop in display field 3
Specification: 12-97 %
-
Check specified value for sender -2- for accelerator pedal position -G185- at idle stop in display field 4
Specification: 4-49 %
NOTES: Engine Control Module (ECM) calculates the voltage values of the angle sensors in percent relative to 5 volts and displays these percentage
values. (5 volts supply voltage represents 100 %).
-
Depress gas pedal slowly until Wide Open Throttle (WOT), and observe percent indication in display fields 3 and 4:
Percent indication in display field 3 must climb uniformly. The tolerance range 12 to 97% is not used completely during this.
Percent indication in display field 4 must climb uniformly. In the process, the tolerance range of 4 to 49% is not completely utilized.
NOTES: The indicated value in display field 3 must always be about twice as large as the value in display field 4.
If indications do not resemble description:
-
Check voltage supply and wire connections of sensor for accelerator pedal position.
