Hello
Can anyone help me find electrical diagrams for the PCM(schematics)
I am looking for 1998 Contour v6 2.5L. I have tried "Alldata" and "Haynes" but its not enough. And the problem i am having deals with oxygen sensors. So i need to see wiring from computer to O2 sensors. What happened is: there are 4 sensors and only 1 is operational (thats what tests show). This means that all load is going on one and its very unusual to have all 3 broken. I did troulbeshoot it and they are operational when swithced around. So my guess is somewhere in the harness.
Please help, cause was having problem for 3months now.
Thanks you in advance
thanks a lot ill give it a shot later. with that engine its really hard to see whole wire for rear O2 sensor in bank2. do you think its a good idea to jump the wires? i already did for 1 sensor cause voltage was 0 and thats why i need to pinpoint others. its too costly-risky to play with harness.
