Question about 2006 Chevrolet Malibu
I have a 2007 Chevy Cobalt that has been throwing a p0128 code recently couple with the fact that when it does the engine temp readout on the DIC reads "---" instead of a temp. I was told that the most likely culprit was the engine temp sensor (coolant sensor) which I had replaced a month ago and it did not help. Car has 47000 miles so warranty is not an option. Does anybody have any ideas of what it could be or what I could do next?
The P0218 Code is primarily intended to indicate a faulty thermostat.
Have the thermostat replaced
Other possible causes that could trigger this code would be:
Low engine coolant level
faulty cooling fan
faulty coolant temperature sensor
faulty intake air temperature sensor
