Innova coder reader says 0118 high input temp sending unit this cross referenced to Haynes repair I replaced sensor properly checked previous and new sensor very close to same resistance values obtained test performed in car while running. Wire harness checks out to ohm value 1 ohm over test lead wire value 1.98 ohms PCM instrument panel does not look burnt the coil for needle has continuity I am unfamiliar with the movement driver IC or related components to verify operation is there a fixed value resistor I can check PCM with Haynes show electrical diagram as pin1 ground through PCM an signal to PCM book says voltage drop is method of PCM calculating temp but book does not mention voltage applied or current level used to reference the voltage drop to check temp sensor actively I'm using a multi meter on an 2000 ohm scale an book temp vs, resistance table to drive around. I know that the PCM can not run closed loop if it can't tell temp what can I do to fool the PCM into a continuous operating temp mode so it won't run in limp or is the last resort a trip to dealer for more money than the car is worth
have the same problem?
