Where is the temperature sensor on a 2014 Jeep Grand Cherokee?
The oil temperature sensor is located on the oil filter/cooler housing under the intake manifold. The coolant sensor is located near the firewall.
Where is the temperature sensor on a 2012 Jeep Grand Cherokee?
Re: Where is the coolant temperature sensor on a 2012… On the left cylinder head (Drivers side). The position is on the left side, at the rear corner, close to the firewall and facing the steering column.
How does the coolant sensor work on a jeep wranger?
Coolant temperature sensor test and change for the Jeep Wranger. Coolant Temperature Sensor monitors the temperature of the water in the engine. The PCM uses this temperature reading to adjust the fuel injection and timing. In some cases the PCM uses the reading from the sensor to turn on the electric cooling fan if so equipped.
Where is the temp sensor on a jeep?
The one wire sensor in the back sends temp readings to the gauge in the Jeeps dash. If you temp gauge isn’t acting right, replace the one wire. The two wire sensor located in the thermostat housing sends its signal to the PCM. For poor performance issues and testing we are going to look at the two wire up front.
Where is the CTS sensor located on a jeep?
Where is the CTS sensor located? On Jeeps there are two coolant sensors. There is one at the front of the engine in the thermostat housing, this one has two wires. Then there is another at the back drivers topside of the engine cylinder head just to the right of the valve cover, this one has one wire.
How does the coolant temperature sensor work in a car?
Coolant Temperature Sensor monitors the temperature of the water in the engine. The PCM uses this temperature reading to adjust the fuel injection and timing. In some cases the PCM uses the reading from the sensor to turn on the electric cooling fan if so equipped.
Where is the coolant sensor on a Jeep Cherokee?
Your Jeep’s coolant sensor (or at least the one that annoying light is referring to) is located in your coolant overflow reservoir. There’s something about the design that is almost guaranteed to cause a failure of some sort. Sometimes it’s the wiring, other times it’s corrosion at the plug. Then sometimes the sensor really us the problem!
What should the coolant resistance be on a Cherokee?
Remove the coolant sensor from the reservoir tank. With the float all the way down, the resistance across the contacts should be zero. Now raise the float up as if you had a full coolant tank — the resistance should be approximately 3.3 ohms.
Where is the CTS sensor located? On Jeeps there are two coolant sensors. There is one at the front of the engine in the thermostat housing, this one has two wires. Then there is another at the back drivers topside of the engine cylinder head just to the right of the valve cover, this one has one wire.
How to change the temp of the coolant sensor?
Also a way to vary the temperature of the sensor. Something like a pan of water on the stove top over low heat. Use a thermometer to measure the water temp as it climbs. Not the water temp as you measure the resistance and compare it to the chart below. See YouTube video at the bottom of the page.
