ECM TEST, tps hay trikster

Hello,



I traced the wires back to the ecm and tested the blue wire for the tps and it still gave me the same reading throughout different points in the harness. I believe that you said it could be a bad ecm then. How can I be sure that it is the ECM?
thanks

rk

Hello Rick,

I just had to go back and check your original post to see if I had sent you the troubleshooting chart for the TPS. I hadn't, so here it is. I will send some more info later.

Thanks
i finaly got arround to checking this out. My wife was sick so you know family frist, she is all better now. anyway I could not get it to run any better, so I also noticed that the wires that tell the injectors to fire where bare and arcking ouch!!! Well I talked to a mechinic and checked the oohms and the common ground to the tpi sensor and it all checked out ok. next well it is probly the computer. auto zone has them for about 80 bucks (learned that on this sight) I will review the info with the mechanic and see what she says and then post a reply with what I found

thanks again

later and
