2000 Dodge Neon 4 cyl Front Wheel Drive Manual 184000 miles
My engine has two trouble codes: P0117 (ECT voltage input low) and P1193 (IAT voltage high). I checked the wiring for both ECT and IAT and noticed they both are connected together in a series circuit directly to the PCM. So I turned the ignition key on and tested to see if there was an electrical current going through the IAT adapter, but there's nothing; neither the ECT adapter had any electrical current going through it. So I'm assuming the PCM is not pumping out an electrical current through these two sensors. Should I replace the PCM or is there an underlying problem?
have the same problem?
