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.
What does the coolant temperature sensor do on an engine?
The engine coolant temperature sensor’s job is to measure the coolant temperature for the engine control module. With this information, the engine control module adjusts the air-fuel mixture depending on the temperature. This article will discuss the most common symptoms of a bad coolant temperature sensor, location, replacement cost.

How does the cooling system work on a Jeep Cherokee?
When coolant temperature is below 190*F (88*C) the switch is open preventing the relay from being grounded and the cooling fan from being energized. When the air-conditioning is used the engine ECU grounds the A/C relay coil allowing current to flow through it.
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.

What does bad light mean on Jeep Cherokee?
If you own a 1990s Jeep Cherokee there’s a good chance you’ve become intimately familiar with the Coolant Sensor Bad light on your dashboard. What does it mean, anyway?
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.
