Will coolant temp sensor keep car from starting?
Will coolant temp sensor keep car from starting?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
What are the symptoms of a bad coolant temperature switch?
1. Poor fuel economy 2. Black smoke from engine 3. Overheating engine 4. Check Engine Light comes on The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant.
What should coolant temp be when engine is hot?
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.
Can a bad coolant temperature sensor keep the car running?
Your symptoms are a dead ringer for a bad engine coolant temperature sensor (ECT). The computer is calculating an air/fuel mixture that is too lean. That’s why pumping the gas pedal keeps your engine running. You can have a bad sensor even without a “check engine” light or trouble code.
What should the coolant temperature be in a VW?
The data sheet for the coolant should have a curve for different concentrations and pressures (although 50/50 and 15 PSIG is very standard). Normal operating temperatures for a VW diesels are in the range of 170° F to 210° F with the thermostat set to open around 190° F.

What’s the name of the coolant temperature sensor?
Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.
