I stopped at a grocery store turned off the engine and went shopping. My car 03 wagon 18t 5sp hasnt been starting recently. Most modern cars with fuel injection have more than one temp sensor one is for the temp gauge and is not so important for starting and running but the other one sends info to the electronic control unit that controls the fuel injection and spark of the engine. The oil pressure sensor on some models may prevent your car from starting if it isnt working correctly. Can a coolant temp sensor keep a car from starting Some cars use the engine coolant temperature sensor to control the electric cooling fans. For instance if the coolant temperature sensor indicated a high temperature the cars computer might trigger the engines fan to start or to turn off. Of course it doesnt matter.

When there is a coolant leak or the engine has a blown head gasket the sensor can be fooled because of the air or exhaust trapped in the cooling system which the sensor cannot read.
