I was recently has having issues with my throttle body so I replaced it with a rebuilt one and the car stared running fine for 3 months. One day while my daughter was driving the wrench light came on and the car would not accelerate. The car started but would not accelerate. We had it towed to the house and I ordered another throttle body assuming that was the issue since it was a rebuilt part. After installing it the car still will not accelerate. After doing some Google searches I am thinking it could be the EMC. But I am unsure how to be sure. Any advice would be appreciated.

 

If the wrench or check engine light is on you should have the codes read. That will most likely point you in the right direction.

 

Ok so here are the codes:
P0122 Throttle position sensor voltage low (confirmed)
P0222 Idle validation signals both low (confirmed)
P2104 Throttle actuator control system forced idle (confirmed)
P2110 Throttle actuator control system forced limited revolutions per minute (confirmed)

I tried to clear the codes but they stay as "pending"

Does anybody know what I need to replace of fix with these codes. Maybe a starting point.

 

P0122 - Some info here: http://www.obd-codes.com/p0122
P0222 - Some info here: P0222 - OBD-II Trouble Code
P2104 - Some info here: P2104 FORD Throttle Actuator Control System Forced Idle | AutoCodes
P2110 - Some info here: P2110 Throttle Actuator Control System - Forced Limited Engine Speed | AutoCodes


The common theme here is an electrical concern with throttle related parts. I would suggest checking the electrical connections of the parts mentioned on the above sites before buying anything. If you find poor electrical connections I would think that you have found the problem, start with the electrical connections on the throttle body.
