Even if you don't feel this addresses your problem, it's good to refresh the info for the newbies or those that may have missed it.
Here is more info and the procedure courtesy of a post by Joey:
"The Accelerator Pedal Position Sensor (APPS) assembly is located under the vehicle battery tray. A cable connects the assembly to the accelerator pedal. A plastic cover with a movable door is used to cover the assembly. The APPS is used only with the 5.7L V-8 engine."
After changing the ECM it states:
"Turn key to ON position. Without starting engine, slowly press throttle pedal to floor and then slowly release. This step must be done (one time) to ensure accelerator pedal position sensor calibration has been learned by ECM."
If changing the accelerator pedal position sensor it states:
"Leave ignition switch ON for a minimum of 10 seconds. This will allow PCM to learn electrical parameters."
Here is the old thread: http://www.300cforums.com/forums/showthread.php?t=1664&highlight=throttle+response Good Luck! |
Little confused here. Do you press the pedal slow or fast. The above quote states to go slow, but when you read some of the treads it tells us to press the pedal as fast as possible?
