Icon9 Out of Ideas

Okay heres how it goes i hav ea 94' ranger 4-cyl i have replaced TPS, Mass Air Flow Sensor, coil packs. i have a check engine light that says that the throttle body is higher or low than the computers operation. i just would like a good answer to this if it the wires going to the throttle body than which wires do what please. so that i can check to see if there is a break and where do the wires start and end. if i cant fix this its going up for sell. cause i have spent so much money on this truck and the funny thing is that even with the light on the truck runs fine i notice htat every once and a while when i drive it seems to not have a little power than what it has.

3/4" x 3/4" piece of electrical tape over check engine light will remedy problem immediately.

Can you post the code that you pulled? I can look it up at work and see if I can help you. Also can you describe the problem you are having?

Have you tried clearing these codes to see if they come back? Disconnect your battery and let it sit for 30 minutes to an hour. Reconnect and drive normal so it can re-learn. I bet the light doesn't come back on.

Did you just blindly replace all these expensive components hoping it would make the light turn off?

Well the problem is you've replaced all these things that have nothing to do with the indicated problem. The MAF, plugs, and wires have nothing to do with the throttle position sensor or the spout circuits. Blindly replacing coil packs hoping the problem goes away also isn't productive.

The codes are indicating a ground fault on one or more of the spout circuits and an invalid reading on the TPS. You more than likely have damaged wires or a loose electrical connector or two somewhere.
