1. Diagnose the cause of the problem:
a) Check the Throttle Position Sensor (TPS) connector and wiring for damage or loose connections.
b) Test the TPS resistance and voltage with a multimeter to see if it's within specifications.
c) Inspect the throttle linkage and ensure it's not binding or sticking.
d) Check the accelerator cable for proper adjustment and operation.
e) Check the air intake system for leaks or blockages.
2. Replace the faulty component:
a) If the TPS is faulty, replace it with a new one.
b) If the wiring or connector is damaged, repair or replace as necessary.
c) If the throttle linkage is binding, adjust or lubricate as needed.
d) If the accelerator cable is not adjusted correctly, adjust it or replace it if damaged.
e) If there are any leaks or blockages in the air intake system, repair or replace the necessary parts.
3. Clear the code:
Once you have repaired the issue, clear the code from the ECU using a scan tool.
4. Test drive the vehicle to see if the problem is resolved:
Take the vehicle for a test drive to ensure the check engine light does not come back on and that the engine is running smoothly.
Note: It's recommended to consult a professional mechanic or refer to the vehicle repair manual for specific instructions related to your Dodge 5.9 model and year.
