Grab a can of aerosol freezer and use that to rapidly cool the sensor.
A hairdryer is useful for the opposite.
As with all faults and as Yamae suggests check the OBDII codes first.
OK, so I decided to try again to read the code(s). Determined that the CEL bulb is burnt out. So I swapped another working bulb with the CEL bulb, put the panel back in, tried to read the codes and found no codes.
I put the crank sensor in ice water after another shut-down, re-installed it, and it started right up!! I was a happy camper. Ordered a new one. Installed it yesterday, July 5th and now it runs so long that I am able to see why she had a new thermostat sitting in the front seat. Overheated in less than 20 minutes. Texted her about that and she decided to let her husband work on that.
When she went to leave (after sundown) she immediately stopped, came back and showed me her NEW PROBLEM. When the car is started, the dash lights come on. When the headlights are turned on, the dashlights turn off. OMG, what next? I am getting afraid to touch anything on this car for fear of causing another problem.
Any thoughts on this? Anyone? Anyone?
