Temp Sensor and Fuel Mix

mardi 21 octobre 2014

Here's the question, will a faulty coolant temp switch cause the ECM to 1) Increase fuel richness, particularly on cold start. 2) Cause the oil injection rate to increase. 3) Increase the load on the CAT (and eventual failure). 4) Cause rich-running, and white smoke on hard accel. and cold decel. And white smoke on cold start.



Thanks
