In the example below the sensor is being held in by a large C clip. Step 15: Remove coolant buckets. Since you are getting clearly weird results from the gauge, I'd check it's transmitter. Chuck CanuckQx4 wrote:Well I did this test today, probed for voltage at the end of the female 3 pin connector, the test says I should have 5V at that pin, I have 4. Do not over tighten the sensor or you will crack the porcelain which will cause the sensor to send false information to the computer. This will cause the computer to think the engine is cold, even when it is not, and as a result will use more fuel than necessary.
That doesn't include getting the new 6. I'm gonna guess the the hardest part is all the rewiring? I've got a 3 part video on 2003+ wiring harness modification, complete start to finish. I've got a 3 part video on 2003+ wiring harness modification, complete start to finish. It may work for other fuel injected Jeeps as well. Pull all the loose wires that go deeper into the harness back past where the original C100, C152 were located.
Here is the tiny metric hole. When the sensor is functioning properly, it will tell your on board computer if the temperature is too high, alerting the driver that a problem exists by illuminating a warning light on the dashboard. C2 information is in these links. Wear protective eyewear and gloves. Pin 10 - White - Engine Speed Signal - Tach signal. I don't remember the brand but I could ask him if you want. Later years should be similar, use circuit 's to compair.
If there is a code it will be code 22 per the light flashes. Once the sensor has been successfully tightened, reattach the wiring harness. What all beside the motor and computer will I need out of the 99. There will be more to come. Part 3 of 3: Start the engine and test drive the vehicle Once the coolant temperature sensor has been replaced, you need to start the engine, check for leaks, and refill the radiator fluid in most cases before you test drive the vehicle. This could be a great Forum section. You can also purchase the new sensor and match it to the sensor on the engine.
I remember we had a 98 Cheyenne work truck with the vortec v6 engine, and it would blow the doors off of my old tbi 350. But I dont think its actually overheating or even getting up to operating temp. The engine block was warm, but not hot, but the sensor is saying 240-250 degrees. Try changing it to no switch or manual. It's too bad they don't have reading for it cold, but I'll bet it's 300-600 Ohms or so, and yours will read less than 200.
But I have the opportunity to buy a 5. This is all you need for stand alone. I was wondering if the ohm range on the sender might be incorrect. Overheating engine Another symptom of a problem with the coolant temperature sensor is an. Refill the Cooling System Once the sensor installation is complete, close the radiator drain valve and refill the system with coolant. And to double-check, it was the Light Green with a Red stripe wire that you measured.
A video of this job being done is at the bottom of this guide. After the clip is removed or the sensor unscrewed grasp the sensor to remove it from the coolant access port. If you want to run without the large under hood fuse block, following info might help to see which wires go where. As you progress into the harness, you will find some ground wires that trace back to splice packs. It's really not a sensor that fails often.
If you want to keep ac, you need to decide whether you're going to run the 5. Once the vehicle has cooled for a minimum of one hour, check the coolant level inside the reservoir and fill if needed. C100, black C152, blue C153, black, 3 wires. Note: Removing all of these will result in a non-emissions friendly harness. The engine is overheating: on the reverse side, sometimes the sensor will fail entirely and won't be able to monitor the engine's coolant temperature. This is C2 - Underhood Fuse Block connector. I know not the same thing but it could be done.
There are two ways to drain a radiator: Either remove the petcock valve and let the radiator drain slowly or remove the radiator drain plug and expect a high volume of coolant to flow quickly. So now I'm wondering that when the truck is standing still in line or park with the engine idling if maybe excess heat is escaping from the header right next to the sensor and therefore the giving false readings. Step 6: Replace drain plug. Thanks for your support :-. Skip the repair shop, our top-rated mechanics come to you.
It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. Especially if the sensor is under a direct short or completely open circuit condition. Part 2 of 3: Remove and replace the coolant temperature sensor The actual process of replacing the coolant temperature sensor is extremely simple. If the sensor uses threads apply a small amount of thread sealer to help stop coolant leaks once the sensor is reinstalled some coolant sensors have sealer already applied. It will also control the gauge reading or engine temperature light on the dashboard. Very detailed info for what to remove, keep, etc is just a few lines down, I leave all this info so you can see changes year to year if you lik. That doesn't include getting the new 6.
