After about twenty minutes I have a working sensor and no worries about the temperature of my engine. Measure resistance between instrument cluster harness connector C237 pin No. What volts should I see when checking the opposite end of pigtail that plugs into sensor? Two new tubes, and some brazing well do the trick, was hoping to find this mystery part somewhere. Will place sensors in pot of hot water and post findings. The electrical resistance of a thermistor decreases as the temperature increases, and the resistance increases as the temperature decreases.
Disconnect the negative battery cable. Also, one tube about ten inches in length goes into a heater core hose, the other smaller tube and hose goes to the throttle body base. Disconnect instrument cluster harness connector C237. If temperature gauge does not indicate hot, go to step 5. Just follow the wire that is mounted to the frame… You need to know which engine.
A passive sensor is connected to a voltage divider network so varying the resistance of the passive sensor causes a variation in total current flow. Checked the sensor, replaced with new one and still nothing. I still keep current with the latest automotive technology. Disconnect Sensor - Ensure temperature sensor connector is in good condition. I have a ford parts its, number 18B402 off of a 1995 Ford 5.
By-Pass Temperature Sensor - Connect a jumper wire between the 2 pins of temperature sensor harness connector. Ford has a very big problem with the Cam sensor, and the Synchronizer. It will stabilize after you drive for a while. How it ran I have no clue, but it would start knocking and studdering. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The wires that run to the connector for the coolant temperature sensor, there are two of them. Car has been in storage for more than 10 years. The gray sensor is inboard to the black sensor and both located top pass side intake manifold. It would come and go, but never lasted long. Dont think computer is getting correct engine temps.
Thermistor-type sensors are considered passive sensors. Do I have a short? The modified signal returns to the as the engine coolant temperature input. I,m guessing sending unit may be inoperable. Then checked ohms at sensor and was ok, did not show open circuit. With mine, the synchronizer did something, and broke the Camshaft positioning sensor.
Could there be other reason for light showing. . Can you tell me what each sensor is, function of? There are 2 sensors one black and the other gray. Checked each sensor with engine on: black 13. The sensor modifies a voltage signal from the Engine Control Module. I just changed the thermostat the old one was stuck open on my 96' Explorer. Flush, and new coolant Probably never been done before.
I do know that the Exploder is running better, getting better… go under your car and there you should see the exhaust pipes running towards the back. Do not go to Ford for the part. If temperature gauge indicates cold, go to step 3. If temperature gauge indicates does not indicate cold, go to next step. This is on the top just above it. Disconnect instrument cluster harness connector C237. I may have to do the repair my self.
Thermistor-type sensors are considered passive sensors. Screw out the… The o2 sensors are located on either side of the transmission. Bank 2 is the drivers side of the engine in your Ford F-150 V6 and V8 Sensor 1 would be close to the engine before the exhaust enters the catalytic converter upstream sensor Sensor 2 would be in the exhaust after the exhaust leaves the catalytic converter downstream sensor , also called a catalyst monitor If it is doing it every once in awhile, then you might have the same problem I did. What should I check next? There is only one sensor. There are actual diagrams on google. The thermostat housing is on the front of the engine.
