Where is the coolant temp sensor on my S-10?
Where is the coolant temp sensor on my S-10?
On my 92 4.3 TBI, there are two coolant “sensors”. One is a Coolant Temperature Sensor and the other is a Coolant Temperature Switch… The Sensor is for the Engine computers to calculate the air/fuel ratio and the Switch gives you the temp reading on the dash.
Where is the temperature gauge on a GM car?
Only one terminal of the sensor will give you a reading, and that one is for the gauge. The other is for the light and won’t come on unless the temperature is above 235. I think the light terminal is the one nearest the slot in the side of the sensor head. The test is best done with the sensor removed from the engine.
When to use a temperature sensor on a car?
Here’s a chart that gives the resistance values at a wide range of temperatures. It’s best to have the sensor at ambient temperature instead of fresh off the engine. It can be used when you pick up a new sensor, too. Take your multi-meter with you and try to determine the room temperature inside the parts store.
What does the temperature sensor on my 87 Tell Me?
Set your meter to Ohms, and see what resistance you get. It will tell you what it thinks the room temperature is. For example, I have a Temperature Gauge Sensor that I recently removed from my 87. The temperature in the house is 77. The resistance tells me that it’s just over 90 degrees.

Where is the temperature sending unit on a Chevy truck?
If your temperature gauge is not functioning properly, replacing the… Replacement temperature sending units for 1967-69 Chevrolet/GMC truck models with factory warning lights. The temperature sending unit screws into the side of the cylinder block or on the intake manifold and allows the temperature gauge to function properly.
What should water temp be on Chevy’s 10 4.3?
The 4.3 was programed by the factory to run it’s best at 190′”, if it runs too cold. The mil light comes on indicating a temperature sensor failure. You can’t post conmments that contain an email address.
Where are the senders on a Chevy truck?
The temperature sender screws into side of cylinder head or on intake manifold to operate Champion or Challenger Series fans. Turn your electric fan on at whatever your desired temperature is with this adjustable temperature sensor. The sensor adjusts from 180°F to 240°F and helps prevent overheating in performance vehicles when driving at…
What are the symptoms of a bad coolant temperature sensor?
Hence, it is advised to have your car inspected right away to avoid any serious problems. Here is a more detailed list of the common symptoms of a bad coolant temperature sensor. One of the first symptoms you will notice is that the check engine light will activate.
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.
Where are the coolant sensors on my 92 TBI?
One at the front of the intake manifold right next to the t-stat, and the second on the driver’s side head. On my 92 4.3 TBI, there are two coolant “sensors”.
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.
Are there coolant temp sensors for Ford Ranger?
Rest assured that we stock customized sensors designed specifically for your make and model, such as a Dodge Ram coolant temp sensor and coolant temperature sensors for Ford Ranger pick-up trucks.You can enjoy our Same Day Pickup option when ordering online.
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.
Can a faulty coolant sensor cause black smoke?
A defective sensor can also produce black smoke from the exhaust pipe, since more gas is being used than necessary. Other indicators of a faulty sensor include difficulty starting your ride after it has reached its typical working temperature, or if your coolant temperature gauge fluctuates irregularly.
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.

How can I check the temp sensor on my car?
To check, try disconnecting the wire that you think is the temp. sensor with the ignition on. The gauge should go down. Then short the wire to ground and the gauge should peg at the top of the scale. I will have to test this tommorrow. The question really isn’t if it works but how accurate.
How many ohms does the coolant sensor show?
When I check the one for the computer it is right around 250 ohms which is close to 190. But the gage only shows about 140 or so. There is only one wire so there is nothing to ground to to check the ohms. I guess it is not that important but I just like thinks to work the way they are made to.

What causes a coolant temp sensor to be bad?
When the PCM senses this low voltage input, it will translate this voltage input to a 250° F temperature. This code is caused by one of the following: Coolant temp sensor’s wires are shorted to ground. Coolant temp sensor’s wires are shorted to each other. Coolant temp sensor is BAD.
How does the coolant temp sensor work on a PCM?
When the PCM senses this high voltage input, it will translate this voltage input to a coolant temperature of -46° F (-50° C). Coolant temp sensor’s wires have an ‘open-circuit’ problem (usually due to a cut wire).
