E36 ODB2 says Coolant Sensor is bad.
Hi, I have a 1995 318ic (E36) and the check engine light will not reset. I replaced the coolant sensor and tried to reset light...didn't work. Tried several times. Both old and new coolant sensors respond to temperature changes. Wiring in loom appears to be in good shape. All temperature gauge reading are normal and the car runs fine. My problem is that the car will not pass emissions with the check engine light on. Thanks for any help available, BillDave 121
