    i have the same problem with my 1999 6 cylinder f150. you can shut off the engine for about 10 seconds and it will reset itself. also you can fluctuate the throttle and make the needle back down to normal. it is strange. it may be a sensor under the intake?

    i have the same problem with my 1999 v6 f150. you can turn the engine off for about 10 seconds and the gauge will reset itself. also you can fluctuate the throttle when the needle starts climbing and it will back down to normal. it may be a sensor under the intake. ???

    2000 F150 5.4 Temp gauge goes up & the oil light comes on. It only seems to happen at low speed/idle. When I accelerate, the gauge drops down and light goes off. There is also sometimes a hum/whistle sound ... like a flute/recorder ... that sound will sometimes continue for a few seconds after the engine is shut off.

Why does the temperature gauge on my 1995 Chevy K2500, 5.7L read 150 degrees ?
If you replaced the SENSOR and not the gauge SENDER, there's your answer.

The SENSOR sends the computer (ECM, PCM, ECU, etc.) the engine temp so it can make the adjustments to the fuel, timing etc.

The gauge SENDER makes the gauge read what temperature the engine coolant is.

Hope the helps.

1992 S10 Blazers Temp gauge quit working. I replaced the temp sensor and still no action. Engine light comes on about the time the thermostat opens and if I shut the engine off and back on it goes out
No. They are spliced together in the harness. Easiest way to fix it is run a new wire to the temp sensor from the power at the TPS.

Right now I have a problem, the thermometer gauge of my ford explorer 1998 4.0 is not working can you give me an idea how to fix this beside bring this to the mechanics my email is ymylyo52@gmail.com,...
open hood, remove the plastic motor cover,remove air intake hose from air filter box to throttle body. under the throttle body you will see a black plastic box that radiator upper hose connects to. this is the thermostat housing. there are two temp sending (sensors) units on the top of this unit. I believe the one on the left is your gauge unit, the one on the right goes to comp for proper temp,air,fuel flow. Now you can unplug this and use a jumper to test gauge. I changed mine and beware, sometimes i just don't understand how these engineers think. (from totally amazing to totally idiotic) they used a hex head threaded sleeve molded in the cover from inside(this is where the sensor screws into) the problem is if the sensor gets a little coroded when you try to remove the sensor it twist this insert and now you have to replace the top half of the thermostat housing. The more i work on my 98 explorer the more i'm leaning to selling it. I got my truck for $500.00 in excellant cond. how ever it had a bad motor. (timing chain slider malfunction which broke motor) this truck is difficult to work on, seems like alot of garbage went into this truck, a frikin money pit aimed at drivers between ages 25-48 .

Temp gage goes up to top of scale, before red. Doesn't go into red. Then will go down to 1/2 way for awhile and the repeats.Took out old thermostat, coolant is at proper level.
Faulty gauge or Faulty Temp Sensor. Replace the Sensor and if this doesn't resolve the problem replace the gauge.

2000 Ford F-150. The oil temp warning light came on and the oil pressure gauge dropped to zero. While accelerating, the pressure gauge goes back to normal and the warning light goes out. No drivability...
Make sure the oil level is correct. If the engine bearings are getting worn, the oil pump is worn or it's screen plugged, that can cause low-RPM weak oil pressure. Try running with 'high mileage' oil at your next oil change and always replace the filter. At some point, you may need to consider overhauling or replacing the engine. Good luck!

98 ford wind star running hot
Warm the engine up to operating temperature. Does the upper radiator hose get warm? If no, then cange the thermostat. If yes, then the thermostat is working fine. On the thermostat housing, there is a sensor. Some engines have 2 sensors. One goes to the computer and the other goes to the temp needle in the dash. Unplug the harness and put a jumper wire in the harness. Turn the key to on, and see if the temp needle goes up. Which ever harness causes the needle to go up, replace that sensor. Hope this helps.

I have a 93 ford ranger. I replaced the water pump, thermostat, and temperature sensor. Now the problem is my check engine light turns on and off regularly, and my temperature gauge goes moves to the right...
Hi there,
The temp guage would not have anything to do with the engine light i wouldnt think, take it to a mechanic who has the right diagnostic equipment to extract the codes to tell you what that problem is. As far as the temp guage goes it might be that its riding on the new thermostat as long as its not overheating it should be fine.
I hope this helps.
