How To Troubleshoot And Fix Gm Coolant Temp Sensor Wiring Issues Earth 1 wire for cluster mounted temperature gauge. 3 wire coolant temperature sensor wiring diagram. the two wires, a “5 volt reference”, and a “ground wire” go to the ecu, and the third wire “earth 1 wire for temp gauge” goes to the cluster mounted temperature gauge by providing an earth link to the temperature gauge. The chart lists the resistance values in ohms (Ω) for a given temperature range. for example, at 32°f, the resistance value for a typical gm coolant temp sensor is around 9,600 Ω. at 212°f, the resistance value drops to around 185 Ω. to use the chart, you need to measure the resistance of the coolant temp sensor using a multimeter.

Diagram Pt100 Temp Sensor Wiring Diagram Mydiagram Online The coolant temperature sensor connector secures the connection in the coolant system wiring harness. over time, the connector can melt or break down due to heat. if your vehicle overheats without warning, the coolant temperature sensor or connector may be faulty. other problems might include your vehicle struggling to start after reaching. How to replace a coolant temperature sensor on 1988 1995 gmc or chevy pickups with the 305 or 350 tbi engines,. Using arduino sensors. 2wheeler september 28, 2016, 2:25am 1. i see posts on occasion about using automotive sensors with the arduino. i have tested a popular gm coolant sensor, part #12146312 with my uno and tested it on the bench. this sensor mounts using 3 8 pipe and has a 2 wire connector. the datasheet is here and lists the mating connector:. Like. iamdave0887. 13485 posts · joined 2007. #8 · sep 7, 2010 (edited) you cannot install any one wire sensor. i bought a brand new sensor from my job (the one the parts catalog said was correct), and the gauge was reading almost 30 degrees too high. the temp probe in the radiator fill said 185 190 and the gauge was well over 220.
