Fixing a car temperature sensor usually costs between $150 and $400 total, including both parts and professional labor. The part itself is generally cheap (around $10 to $50), but you are primarily paying for the mechanic's time to locate the sensor, replace it, and drain/refill the engine coolant.
Average Temperature Sensor Replacement Cost
Most owners can expect to pay between $150 and $400 for a complete temperature sensor replacement, including both parts and labor. This range reflects the wide variation across vehicle types and repair facilities.
The only real issue is that the engine might not be running very efficiently. Your computer changes variables based on the temperature of the engine. Your engine should still reach and maintain operating temperature as long as the thermostat is doing its job.
Normal Coolant Temperature
If your engine's temperature gauge ever goes into the red zone, you should stop the car immediately before you cause any serious damage to the engine. Normal coolant temperature will be around 195 to 220 Fahrenheit (approx. 90°C) and anything outside of this range can start causing problems.
Other causes for sensor failure include bending the sensor sheath, hysteresis (which occurs when a temperature sensor lags or is affected by previous readings), leakage current, strain, or mechanical shock.
What Are The Symptoms of a Faulty Temperature Sensor?
Battery-powered temperature sensors typically last between 1-10 years in continuous monitoring applications, depending on transmission frequency, environmental conditions, and battery type. Most wireless IoT sensors achieve 2-5 years of operation, while basic data loggers can extend beyond 10 years.
Common Issues with Cadillac XT5 Engines
The average cost for a Cadillac XT5 Engine Coolant Temperature Sensor Replacement is between $767 and $957. Labor costs are estimated between $403 and $591 while parts are priced between $364 and $366. This range does not include taxes and fees, and does not factor in your unique location.
You can swap it without draining the coolant. You better be quick though. Switch it out and adjust coolant level as needed. If it is been a while typically, 5years/ 100k miles then might as well change it.
ECT sensors do not have an exact lifespan. Still, with proper care of their cooling systems and regular maintenance, they could last between 100,000 and 150,000 miles. Regular servicing will extend this sensor's lifespan.
Dust, other contaminants, vibrations, shocks and exposure to high temperatures all have a shortening effect on the average lifespan of a sensor, so it is important to look for a solution that overcomes these problems by design, rather than just accepting frequent sensor failure and replacement as part and parcel of ...
Typically, replacing the evaporator temperature sensor requires approximately 1.5 to 2.5 hours of labor.
When the temperature sensor starts to fail, your check engine light will come on. This may be the first sign of a problem, so it won't be immediately obvious what the problem is or that it's really a problem. But it's important to not ignore the light—instead, schedule an appointment as soon as you can.
Poor Fuel Economy A faulty temperature sensor causes the transmission to operate inefficiently—staying in lower gears longer than normal, shifting incorrectly, or failing to upshift when it should.
Automotive Technician Training 101: Signs It's Time to Replace the Engine Coolant Temperature Sensor
How can you tell if a thermostat is bad?
Disconnect the old thermostat and unscrew the mounting plate. Check the new thermostat instructions for compatibility and wiring guidance. Connect the labeled wires to the new thermostat. Attach the new mounting plate to the wall.
A bad coolant temperature sensor can lead to erratic gauge readings, engine overheats, cold or rough starts, emissions problems, and poor fuel economy. You see, the engine coolant temperature (ECT) sensor plays a quiet yet critical role in the operation of your vehicle's engine.
As for long-term durability, the Cadillac XT5 can be a reliable vehicle with proper care. Many owners have reported driving their XT5 for over 100,000 miles without major issues, which is a good indicator of longevity.
The average cost for a Cadillac XT5 Thermostat Replacement is between $989 and $1,183. Labor costs are estimated between $415 and $609 while parts are typically priced around $575.
With that said, we highly recommend avoiding the following XT5 years due to reliability issues and complaints: 2017 Cadillac XT5. 2018 Cadillac XT5. 2019 Cadillac XT5.
General Motors LLC (GM) is recalling certain model year 2017 Cadillac XT5 vehicles manufactured April 16, 2016, to May 9, 2016, and 2017 GMC Acadia vehicles manufactured April 19, 2016, to April 22, 2016. The front brake calipers may have a torn or misaligned caliper piston seal which may allow brake fluid to leak.
As a whole, consumers found the vehicle's comfort and reliability to be its strongest features and value to be its weakest. 47 out of 78 of owners (60% of them) rank the 2017 XT5 five out of five stars. Overall, consumers seem aligned in their opinions of the 2017 Cadillac XT5.
