Temperature Sensors: Types, How It Works, & Applications - Encardio Rite

Vehicle came in with a camshaft sensor fault. Customer had already replaced the cam sensor — issue remained. We started with the basics, fuel pressure checked it's within spec. Spark present, initially appeared weak Instead of guessing, we checked live data and immediately saw a red flag. Intake Air Temperature stuck at –40° That reading doesn’t mean cold air it means the engine computer isn’t processing the signal. From there, . Sensor resistance tested — OK .Wiring, power, and ground verified
