Why is my coolant temp not reading?
The most common cause of faulty temperature readings is a broken coolant temperature sensor (CTS). The part, which is normally located near a vehicle’s thermostat near the base of the radiator (consult your owner’s manual or repair guide) can get gunked up and fail. Disconnect the temperature sensor’s wiring connector.
Why does my car say its overheating but it’s not?
If you find that you’ve got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.
Why does my engine temperature gauge stays on cold?
Reasons Why your Engine Temperature Gauge Stays on Cold 1. Faulty Engine Coolant Temperature Sensor 2. Faulty Gauge/Cluster 3. Broken wires to the sensor or to the gauge 4. Bad Thermostat 5. Corrosion in connectors 6. Air in the coolant system 7. Broken engine control unit
Why are the temperature readings in my car not showing up?
If you can find the temperature readings in the engine control unit but not at the cluster, you have to make sure that they are using the same sensor. If this is the case, you have to measure the temperature output on the engine control unit. To do this, I recommend letting a car electronics expert do the job for you.
What are the most common problems with engine temperature readings?
The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself, sending the information to the cluster. Some cars have two temperature sensors, while other car models have one.
How do I know if my car has two temperature sensors?
If you have two temperature sensors on your car and one separate for the gauge, you need to check the sensor’s wires to the gauge or ohm measure the sensor from the cluster connector.
