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, and electronic
throttle control actuator terminal 6 and ECM terminal 54.
• Continuity should exist.
• Check harness for short to power or short to ground.
Is the check result normal?
Yes
>> Go to the next step.
No
>> Repair or replace the open circuit, short to power or short to ground in harness or connectors.
8.
CHECK THE TPS GROUND CIRCUIT FOR AN OPEN OR SHORT
• Check continuity between the electronic throttle control actuator terminal 2 and ECM terminal 78.
• 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 or replace the open circuit or short to power or short to ground in harness or connectors.
