2
Turn the ignition off.
Disconnect the PCM harness connector.
Disconnect the APP Sensor harness connector.
Remove the ASD Relay from the PDC.
Connect a jumper wire between cavity 30 and 87 of the ASD Relay connector in the
PDC.
Turn the ignition on.
Measure the voltage of the 5 Volt Supply circuit in the PCM harness connector.
Is the voltage above 5.2 volts?
All
Yes
→ Repair the 5 Volt Supply Circuit for a short to battery voltage.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
No
→ Go To 3
3
Turn the ignition off.
Disconnect the APP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the APP Sensor Signal circuit and the 5 Volt Supply
circuit in the APP Sensor harness connector.
Is the resistance below 100 ohms?
All
Yes
→ Repair the APP Sensor Signal circuit for a short to the 5 Volt
Supply circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
No
→ Go To 4
4
Turn the ignition on.
With the DRBIII
t in Sensors, monitor the APP Sensor Input voltage.
Slowly press and release the Accelerator Pedal.
Is the voltage change smooth as the Accelerator Pedal is pressed and released?
All
Yes
→ Go To 5
No
→ Replace the Accelerator Pedal Position Sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
5
Turn the ignition off.
Disconnect the APP Sensor harness connector.
Turn the ignition on.
Measure the voltage of the APP Sensor Signal circuit in the APP Sensor harness
connector.
Is the voltage above 5.0 volts?
All
Yes
→ Repair the APP Sensor Signal circuit for a short to battery
voltage.
Perform POWERTRAIN VERIFICATION TEST VER - 5 - 1.6L.
No
→ Go To 6

NOTE: Before Continuing: Disconnect the PCM harness connector and
check the related wiring terminals for corrosion, damage or terminal push
out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.
