NTK Engine Coolant Temperature Sensor,Engine Oil Temperature Sender P/N:EF0103
NTK EF0034 coolant temperature sensor for the 2008-2011 Jeep Wrangler V6 3.8L, the 2012-2013 Wrangler V6 3.6L and other vehicles measures the temperature of the engine coolant. Also known as an engine coolant temperature sensor, it sends an analog signal to the ECM so the ECM can hold the proper air/fuel ratio and run the cooling fan and temperature gauge correctly.
A check engine light, an erratic temperature gauge or a cooling fan that runs erratically or not at all can mean this sensor is worn, though the thermostat or the cooling fan relay can be behind them too, so trace the cause before you buy.
It is a coolant temperature sensor for the 2008-2021 Jeep Grand Cherokee V8 5.7L and the 2017-2021 Jeep Compass 4-cylinder 2.4L as well. If your own car is not named here, look it up on the Buyer's Guide tab. This listing is one sensor, and the 2012-2013 Jeep Wrangler V6 3.6L takes one. Wires and probe length match OE.
