How to Test a Coolant Temperature Sensor
Your coolant temperature sensor communicates important info to the car's computer. I suspected the CTS was faulty on my 1995 Oldsmobile 98 Regency Elite. In this video we've put the old sensor next to a new sensor and run some resistance tests based on GM's tables. We'll run the tests at 32 degees, 70 degrees, and 212 degrees. All you need is a multi-meter on the Ohms setting. I hope this helps you. Please like and subscribe. Buckwsr, putting the "Do" into "Do-It-Yourself."
