2 Wire Temp Sensor Coolant Temperature Sensor Wiring Diagram Sensor 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. in three wire coolant temp sensors, the ecu does not control the. You're confusing the temperature sender (one wire and a grounded body) and the ect sensor (two wires, not grounded to the block). the sender operates the gauge in the instrument cluster. the sensor sends info to the ecu. he's not having monumental problems here. just needs to replace the pigtail on the wiring harness.

2 Wire Temp Sensor Wiring The wiring diagram for the engine coolant temperature sensor typically includes three wires: a power supply wire, a ground wire, and a signal wire. the power supply wire provides voltage to the sensor, while the ground wire completes the circuit. the signal wire carries the temperature data from the sensor to the ecu. The coolant temp sensor wiring diagram illustrates the electrical connections for the sensor. it typically includes the wire colors, connector pinouts, and any related components in the circuit. the diagram acts as a guide for mechanics, technicians, and car enthusiasts who need to understand how the sensor is wired to ensure accurate readings. Step 1: gather the necessary materials. before you start wiring the coolant temperature gauge, make sure you have all the necessary materials on hand. these may include a gauge, wire, connectors, crimping tool, heat shrink tubing, and a soldering iron. having these materials ready will ensure a smooth and efficient wiring process. For example, as per the service bulletin 05 002 12 for the 2011 dodge journey with the 2.4l engine, to repair the trouble codes p0117 (engine coolant temperature sensor circuit low) or p0118 (engine coolant temperature sensor circuit high), the brake booster vacuum hose that was routed too close to the ect sensor connector must be replaced.
