Engine Temperature Gage at the Instrument Panel not working

Your temp.gauge is probably bad ! Check for voltage at the coolant temp. sender ! You have to check it with the engine running . The red with white stripe should have a voltage the other wire ,yellow with red stripe is ground side ! Instrument panel fuse box fuse # 15 a 10amp fuse powers the gauges ,if your gas gauge works it's not the fuse . The dome lights get there power from an other fuse an circuit ! Did you check the bulb ? Check fuse # 8 IP fuse box , also a 10amp . Check for voltage at the dome light ,switch on !

My 1999 ford explorer's gauge says its overheating but you can open the radiator cap and it was only luke warm just started and drove 1 mile?

It is possible for the engine to be overheating while the radiator seems to be cool. If the thermostat is stuck closed, the water will not circulate to the radiator. Simple check. Remove the thermostat and place it in a pot of water. Heat the water on a stove and observe when or if it opens as the water heats up. If it opens before the water boils, it is good. While you have it out, you might as well replace it anyway.

My temp gauge quit working and i replaced sender and gauge. it's got to be a short. but where to start maybe someone else has had the same problem

95 yj (quite means, hot , low or mid?,) just a clue.?
4.0L? all fuses good,?
the FSM covers this , here is the outline (all cars this era)

1: IR pyro gun pointed to thermotat housing near 180f 170f min.
2: ok engine really IS hot. then we ground the gauge feed, meter,
pegs, meter good , I use a light bulb from ground to guage to
limit current (im nice to my meters)
3: i then find my temp sender, the one with 1 pin.
pull the connector with a hot engine
this is a passive NTC thermistor and is not the ECT with 2 pins.
its just for the gauge.
the 91 sender is different from a 95 so dont mix years,!!
92-95 are matched.

hot engine, 180F or more...
pull off the single wire. to the sender.
connect DMM set to OHMS (yes, omega symbol i s that)
select 200 or 2000 range, id use 2000, , if an auto ranging meter
let it range and read the LCD markers, it tells you what range it landed red to pin, the black to engine block. (rear top sender on 4.0L)

its not the sender bad, all in 5min work. no guessing at all

so if its good, the wires are bad. twinxed them.

the only hard part is finding good ohms charts that match your year.
all else is caveman simple 1 wire, gauge and sender.

i see many folks online mixing wrong clusters in jeeps
and wondering why the right sender dont work.
so did you cluster temp ever work right, this year, this decade?
ohms law , never lies, but wrong parts do.... every time.

the sender is NTC, higher ohms cold, , lower hot !

i could not FIND the sender spec. at all.
1million hits for ETC, zero for gauge.

my guess is sender will read high ohms cold , 1000 or more. more cold more ohms... (resistance)
then drop in ohms as engine warms might drop to as low a 80 ohms.
but will drop , gauge wire (it only has 1) disconnected.

1994 Mercury Grand Marquis temp gauge reads hot

Check sending unit, Ford/Mercury put out a TSB, technical service bulletin : Article No. 95-13-2 07/03/95, on erratic temp sender units.
You troubleshoot as follows :
  1. Turn ignition switch to On or ACC position.
  2. Connect a 10 ohm resistor between gauge lead and ground. The centerline of pointer should fall within the band around the H mark.
  3. Connect a 73 ohm resistor between gauge lead and ground. The centerline of pointer should fall within the band around the C mark.
  4. If gauge tests within calibration, replace sender.
  5. If gauge is out of calibration, replace gauge.

Where is the temp gauge sensor on a 95 cutlass ciera 3100

If you are finding water in the oil, then you have a serious engine problem, possibly a blown head gasket. If that is the case, it is highly likely that the high temperature reading is correct, and changing the sender wont fix anything. I suggest you get a mechanic to check it out and see if you have a serious engine problem before you spend any money on repairs.

Spark knocks going up hills also temp gage not working

What do u mean by spark knock? Missfire? Temp gauge not working could be a few things, sender fault, no water, gauge fault or wiring. Check u have water in it. Then find the sender and earth it out, gauge should go all the way up, if it does replace the temp sender, if not it's gauge or wiring. Let me know about the spark knock.. Not sure what u mean

Dual gas tanks on a Ford F-250, one stopped registering and the other is working fine.

This is probably caused by a bad level sender in the tank. You can test this by disconnecting the electrical connector nearest the sender and connecting to a gauge tester or an appropriate electrical resistance. If the gauge operates correctly, then replace the sender.

Fuel gauge reading zero and light on ?

Ford has lots of problems with the sender reliability. Typically, the sender (and expensive fuel pump) replacement resolves the issue. To test, you need to take the connection off of the sending unit, at the tank, turn on ignition, and then ground and un ground it and view results at the gauge. If the gauge responds, the sender needs to be replaced.

There are aftermarket senders that cost less than OEM.
