Is there a 2 pin coolant temp sensor?
I needed the single-pin one for the coolant temp gauge on the side of the block, but they gave me the 2 pin one for the intake. I was able to source the sensor from autozone once I realized the mistake. So, I have a 1994 Chevy Silverado 1500 2wd with a 350 cu in TBI with a bad coolent temp sensor.
How can I tell if my coolant temperature sensor is bad?
To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
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.
How much does it cost to replace a coolant temperature sensor?
Unscrew the ECT sensor in an anticlockwise direction, similar to how a spark plug is removed. Install the new sensor and reconnect the connector cable. The average replacement cost of the Coolant Temperature Sensor is between $100 and $220. The labour cost is between $40 and $140 while the part itself costs between $50 and $80.
What should the temp of the coolant sensor be?
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. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.
Can a bad coolant sensor cause a car to not start?
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.
Where is the coolant temp sender on a Bambino?
Nevada_545said, “The coolant temp sender for the gauge has one wire, dark green. That one is in the left cylinder head between the first two spark plus.” “The coolant temp sensor for the PCM has two wires and is located near the thermostat.” We haven’t heard from the bambino since November.
Where is the coolant temp sensor on a GMC Sierra?
The coolant temp sensor for the PCM has two wires and is located near the thermostat. Assuming this is not a diesel engine. In Summary… bambsbambino said, “So I got a 98 GMC sierra and the ect sensor that is on it only had one wire running to it. Obviously the previous owner tried to make something work.
