Hello All,
Recently had my thermostat read out shut down on me when driving home from a work trip. Immediately pulled over to ensure I was not overheating and when turning the car back on the read out turns back on. The car is not overheating currently as on occasion the thermostat will turn back on when operating and will be at a normal operating temp. I have also shut down the car at lights and when restarting the temp gauge will turn on and reflect proper operating temps for at least a couple of seconds. Pulled the code and confirmed it was P1289 a head temp circuit. Have not recently done any work on the car so it is unlikely it was unlodged by my maintanance. When the temp readout ceases functioning the AC also stops blowing cold.
Any thoughts to addressing this? Their do not appear to be any functional issues with the car (beyond the sensor) at this time. Looks like the temp sensor is pretty cheap. Doing some googling to find the location and replacement process.
