Michael, First thing I would do is check the TEMPII sensor. That can be easily done by removing the ECU plug and comparing the resistances of Pin 10 (TEMPII sensor) with pin 9 (TEMPI sensor). Use pin 6 as common reference (ground). This must be accomplished before the vehicle has been driven i.e. the engine is at ambient temperature. That way the TEMPI sensor will be at the same temperature as the TEMPII sensor, and hence at the same resistance. I would expect them to be within 5% of each other.
