* If a DTC P0125 and DTC P0128 are both set, a skewed ECT sensor is the most likely cause. * A skewed IAT sensor may cause this DTC to set. The IAT sensor should read near ambient temperature with the engine running. It could be a bad coolant temp sensor or a bad inlet air temp sensor but is most likely a bad thermostat.
Aug 21, 2020· I ask because there is two sensors inside the cylinder head. One on top and one on the bottom. I thought that was the coolant temperature sensor in the thermostat housing.

Mar 25, 2021· How the Temperature Sensor Works. On most vehicles, the coolant temperature sensor (CTS) can be found somewhere near the engine thermostat, which allows it to function optimally. The tip of the CTS is probably located right next to the engine coolant. The sensor works by measuring the temperature that’s being given off by the thermostat and ...
Oct 16, 2021· A car engine works much the same way, averaging between 195220°F. One of the main components in charge of regulating how hot or cold it gets is the thermostat. How does a car thermostat work? Simply put, it responds to temperature changes in the engine coolant. If it is cold, the thermostat stays closed, keeping it in the engine.
Dec 15, 2020· Coolant Temperature Sensor. Many latemodel cars and trucks use electric radiator fans. To cycle the fans on and off, the computer relies on signals from the engine coolant temperature sensor mounted at the top of the engine. When the computer registers that the coolant temperature sensor reading has risen above a certain point, it turns on the radiator fans.
Feb 14, 2016· February 14, 2016 — A car thermostat is responsible for preventing your engine from overheating. Unless an engine overheats or fails to reach normal operating temperature after being ...
What does a temperature sensor do in a car?

Apr 27, 2016· Since about midwinter I''ve been having trouble getting the car up to normal temp. It typically hovers around the line one below 190. I''ve seen some people say the coolant temp sensor is more likely to go. However, based on what I''m seeing, I''m guessing it''s the thermostat. * Now that it''s getting warmer in the afternoons the engine gets up to 190.
Jun 29, 2018· The ECT sensor, also commonly just called the coolant temperature sensor, measures how hot the engine in your car is. Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is …
Feb 18, 2021· If your car’s thermostat is working correctly, the hose should feel cool. Remember how the thermostat only opens up at around 185 degrees Fahrenheit? A good thermostat should not allow warm coolant to flow through the hose until the coolant gets hot enough. If the hose is warm it means that your car’s thermostat has gone bad and is stuck open.
2. Replacing the Temperature Sensor. If the car continues to overheat even after installing a new thermostat, the problem could be caused by either a defective temperature sensor or a defective fan motor. Replacement of the water …
Sep 24, 2020· A thermostat is just the next thing that you''re working on that you shouldn''t be. Really disappointing because the Acadia is a nice vehicle and a great road car, especially with the V6. 2017 Acadia
