Labor cost depends on the number of hours mechanics spend fixing your issue and the hourly rate for these mechanics. Engine will have bad mileage and low power and could overheat when a coolant temperature sensor is bad.

car These problems do not necessarily mean an issue with the coolant temperature sensor. For the part itself and depending on the car’s type, expect to pay between $123 and $167 for a coolant temperature sensor replacement cost. If oil gets mixed with the coolant fluid, it is considered as contamination and can cause significant issues with the coolant temperature sensor. The Powertrain control module microprocessor can be called the brain of a vehicle. Though this can result from a number of causes, one of them can be an improper air/fuel mixture incited by a broken temperature sensor. Changing the coolant temperature sensor. So please keep replacing it every now and then. The transmission speed sensor can be found in the rear of a longitudinal mount transmission. LEARN MORE. This is specifically important in “hot start” situations due to the effect of the fuel vaporization as it relates to temperature. With excess fuel in the combustion chamber, not all of it is burned, leading to some of the gas getting burned in the exhaust pipe. This can also be tested by using an Ohmmeter, which will identify whether or not the sensor’s resistance is within specifications.
