Jeep Compass Engine Coolant Temperature Sensor Guide: 2007-2011
Is your Jeep Compass running rough, getting poor gas mileage, or showing a check engine light? A bad coolant sensor could be the culprit.
- A bad ECT sensor on a 2007-2011 Jeep Compass commonly causes a check engine light, poor gas mileage, and rough running.
- This is an easy and inexpensive DIY repair; the sensor is accessible on the thermostat housing and requires basic tools.

Is Your Jeep Compass Coolant Sensor Failing?
When the Engine Coolant Temperature (ECT) sensor on your 2007-2011 Jeep Compass starts to fail, it sends bad information to your vehicle's computer. This can cause a variety of problems, from annoying to potentially damaging. Because the sensor is critical for managing engine performance and cooling, ignoring the symptoms isn't a good idea.
Common Symptoms of a Bad ECT Sensor
🎬 Check out this video on diagnosing overheating and starting issues.- Check Engine Light: The most common sign is an illuminated check engine light on your dashboard.
- Poor Fuel Economy: If the sensor incorrectly tells the computer the engine is cold, the computer will inject too much fuel, wasting gas.
- Engine Overheating: A faulty sensor might not signal the cooling fans to turn on when needed, leading to overheating.
- Black Smoke from Exhaust: A "rich" fuel mixture (too much fuel, not enough air) can result in unburnt fuel burning in the exhaust, creating black smoke.
- Rough Idle or Misfires: Incorrect fuel and timing adjustments can make the engine run poorly, especially when idling.
- Erratic Temperature Gauge: The temperature gauge on your dash may behave strangely, reading too high, too low, or not moving at all.
