Hey guys im new here. Asked this over on FJ but no real answere. My temp gauge wasnt reading so i replaced the CHT sensor since i get -40 reading while in test mode. Im still not getting a reading and it still says -40 so i replaced it with another one and ive still got the same reading with the guage never moving. What else should i check? This is stopping me from getting tuned all the way since the car is stuck in warm up mode.
