While troubleshooting my car, I found the wires to the speed sensor and TCC solenoid all five wires were bare were touching. Maybe that is why the speedometer only shows zero when the car is driven
I cut out the bare wires and spliced them. When I tried to start the car, it turns over but will not start. I got a check engine light. When I installed a jumper wire between terminals a and b on the diagnosticv terminal, I got code 54. This code on page 6-15 in my Haynes repair manual, reads, the mixture control solenoid voltage is high at the ECM because of a shorted M/C solenoid circuit/ or faulty ECM. My car is fuel injected and does not have a mixture control solenoid. That part is on a carburated engine.
I ordered a new ECM. Before I change it, I would appreciate input on my problem. I have checked all of the wiring to the ECM, battery, starter, TPITCC solenoid, speed sensor and speed sensor buffer. All of the fuses are good.
have the same problem?
