stalling jeep

[page1]

no i didn't but i did not hook them up to the plug until i was finished. what happens if you put them in with the battery still hooked up?

Whenever you replace an electrical component the battery needs to be reset, either by disconnecting the battery before replacing the component or taking it to the dealership to have them reinitialize the computer. and disconnecting the battery afterward to attempt to reset it will not work, you will either have to replace the component again (remembering to d/c the battery befre removing) or take the jeep to the dealership to have them reinitialize the computer.

ok i understand what you are saying now. well when i hooked up the tps the check engine light turned off. I was looking at the plugs that go into the ecu or ecm and when i move them like a centemeter the car hesitates and if i do not move it back they car will stall kinda of like what it does when i drive it or just let it idle by itself . another question how much roughly would it cost to get my computer reprogramed. Is there a chance that my computer could have relearned it by its self because the check engine like was on until i turned it off and on a few times and it went out. another thing is that as soon as i got the tps installed my jeep took a few times to turnover but it did and it ran good until it stalled after ildeing for a good 10 mins. what do you think?

when you played aroudn with the connector at the PCM the jeep shuttered?

Check the wiring at the PCM, you might have a broken wire there, you will have to remove the black cover over the wires. I had a couple problems with a broken wire here, just a few months ago I had a problem with one of the wires going to the PCM (from the O2 Sensor) and my CHECK ENGINE light kept coming on after the jeep would reach normal operating temp and the code was for the O2 Sensor and I traced it back and found the wire was broken right where it enters the PCM connector.

Also check to make sure the 8mm bolt is tight. It should be snug not too tight

[page1]

do you think this could be the stalling problem. i will be sure to do that. i did the home diagnostics and before we replace the tps the code was coming up and high and low voltage to the tps or somthing along those lines the code was 123 122

[page1]

which bolt are you talking about

[page1]

should i unplug the wires from the ecm first or sholdn't i do that

[dksob81]

Have you checked for codes since replacing the TPS?

The bolt in the center of the PCM connector. The PCM is located on the passengerside firewall in the engine compartment, behind the coolant overflow bottle.

[page1]

yes i did and it was saying 505 throttle malfunction somthing like that but i have not checked it in a few days the light hasn't come on if thats what you are asking

[page1]

i will check on the bolt is that bolt like a ground or somting yeah i know the the ecm is located

[dksob81]

No the bolt is not a ground, it actually just holds the connector tight to the computer. If it is not tight, then disconnect the battery, unbolt the connector from the computer, then remove the black protective cover and look for any broken wire.

You might want to remove the coolant overflow bottle, it iwll make getting to the PCM easier.

[page1]

i will be sure to check that out and this time i will take the terminals are off to make sure i do not unset anything. i appreciate the help i am logging off i will keep you updated on the out come talk to you later

[dksob81]

also, code P0505 - Idle AIr Control Motor Circuit. A shorted or open condition detected in one or more of the idle air control motor (valve) circuit.

This could be the cause of that shutter you got when playing with the PCM Connector, I think the problem might be a problem with the wiring going to the IAC Valve. When your stalling occurs does it happen at closed throttle or while pushing on the gas?

[page1]

it happens during both pressing on the gas and when it is closed i am not sure if it still reading the 505 code anymore i will get the diagnostic tool from my friend again and i will see what it is telling me.
