What would cause my temperature gauge not to work?
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.
Where is the temperature sensor on a PT Cruiser?
It’s literally just a temperature sensor that monitors the coolant. Yep. It’s that simple. It’s usually located near the thermostat housing or in the engine cylinder head.
Why is my temperature gauge always on cold?
Reasons the Temperature Gauge Reads Cold On most vehicles, the temperature gauge reads cold until the engine has run for a few minutes. With the thermostat stuck open, the engine can be overcooled, causing a low temperature reading. If this is the case, the thermostat may need to be replaced.
Is there a fuse for the temperature gauge?
If there’s no light, check the gas gauge fuse. If the fuse is good, connect a jumper between the ignition and the positive side of the gauge. If it works, you need to replace the wire between the ignition and the gauge. If the light turns on, then you’re running 12 volts, and it’s the gauge itself you need to replace.
Can you unstick a car thermostat?
Start your engine and let it idle for 10-20 minutes. From a cold start, your vehicle’s thermostat will stay closed and you won’t notice any coolant flowing into your radiator. Leave the vehicle running for about 10-20 minutes so it can reach its optimal running temperature.
How do I know if my PT Cruiser water pump is bad?
The two most common signs of a bad pump are leaks and noises. Leaking water pumps can result in damage to the drive and timing belts, and cause the engine to overheat. A failed water pump can be caused by other problems in the cooling system, such as a bad thermostat, radiator or head gasket.
How do I know if my temp gauge is working?
How to Test a Temp Gauge
- Unplug the temperature gauge from the sending unit.
- Turn the ignition key to the “On” position.
- Ground the temperature gauge wire to the engine.
- Check the temperature gauge inside the car.
- Turn the ignition key to the “Off” position.
- Check the fuses inside the car.
How much does it cost to fix a temperature gauge?
The average cost for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 and parts are between $66 and $88. Taxes and fees are not included in the estimate.
