Engine Coolant Temperature Sensor Purpose Location And Failure Signs The ect sensor is a high authority sensor whenever the engine is cold because ignition timing is tailored according to the engine coolant temperature. it also provides input for idle air control (iac) position, oxygen sensor closed loop status, on off times for the canister purge, and idle speed. Learn how to diagnose and replace a faulty coolant temperature sensor, which monitors the engine's cooling system and affects performance and fuel economy. find out the location, symptoms, and steps of the replacement process for different vehicles.
Coolant Temperature Sensor Location Manual Here is a more detailed list of the signs of a bad or failing coolant temperature sensor to look for: 1. check engine light. one of the first signs of all coolant temperature sensor symptoms you will probably notice is that the check engine light will show up on your dashboard. if the computer detects any problem with the sensor’s circuit, it. The engine coolant temperature sensor is responsible for monitoring the temperature of the engine coolant. it sends this information to the engine control module, which uses it to adjust the fuel injection and ignition timing. this helps ensure that the engine runs smoothly and efficiently, and that the emissions are kept within acceptable. Learn how to locate, test and swap out the coolant temperature sensor on your vehicle. follow the step by step guide with photos and tips for this beginner level project. Learn about the ect sensor, which measures the temperature of the liquid coolant and sends a signal to the engine computer. find out how to test the sensor resistance, voltage and location, and what problems can cause faulty readings.

Ok. so now you're ready to replace the ect sensor. 1. park your car in a safe place where you can work comfortably and let the engine cool. 2. place a clean drain pan under the radiator, open the radiator valve and drain about two to three quarts of coolant (or just enough to drop the level below the sensor). Step 2. locate the coolant temperature sensor. many engines have multiple sensors that look similar to each other, so an investment in either a paper version or an online subscription for your vehicle’s repair manual will pay dividends in a generally faster repair and reduce guesswork by guiding you to the exact part and location.
