CHECK THE APP SENSOR
• Connect all harness connectors that have been disconnected.
• Turn ignition switch on.
• Check voltage between ECM terminal 16 (APP sensor 1) and ground, and ECM terminal 40 (APP sensor 2)
and ground harness side, under the following conditions:

Is the check result normal?
Yes
>> Go to step 11.
No
>>
Replace the Accelerator Pedal Assembly (See Accelerator Pedal Position Sensor Removal & Installa-
tion in Section 03 Electronic Engine Controls).
Perform accelerator pedal position learning.
Perform throttle valve position learning.
7.
CHECK THE TPS SIGNAL CIRCUIT FOR AN OPEN OR SHORT
• Turn ignition switch off.
• Disconnect the ECM electrical connector.
• Check continuity between the electronic throttle control actuator terminal 5 and ECM terminal 38.
• Continuity should exist.
• Check harness for a short to power and short to ground.
Is the check result normal?
Yes
>> Go to the next step.
No
>> Repair circuit for an open, short to power or short to ground in harness or connectors.
