Took readings on chassis side connector, 1.32 volts. Understand it should be 5V. What's next? Code P0115 displayed when emission check run. Temperature normal, instrument at 3 o'clock
Replaced ECT to clear check engine light. New Volvo part. still on. 1.32V on 1996 Volvo 850
5 volts should be the reference voltage from the ECM to the ECT, do you have that? The voltage signal that goes to the ECM will be lower, and that may be what you are measuring?
