Check Engine Temperature warning

My "check engine temperature" warning comes on at random times. The temperature gauge will move to hot and them move back down to normal with in 60 seconds. I my fan is louder than normal when this happens. What could be causing this? Is is doing damage to my engine?

    I have the same exact problem.

  • jeparady Sep 28, 2008

    I disconnected the battery for about an hour to clear the car's computers and followed the Owner's Manuals in the Maintenance section to allow the computers to relearn. This seems to have resolved the problem.



    Good luck.

    The problem began to re-occur so I broke down and took the car into the dealer to read the codes for the check engine light. They told me that the thermostat needed to be replaced and wanted $650, plus parts to do so. I paid the $95 for the diagnostic test and went to Kragen and special ordered the thermostat and gasket for $30. It took me a little less than an hour to replace it. The old one had a series of cracks around a brass bowl that was causing it to "hang up" in its housing causing the occassional overheating. Apparently waiting a few minutes with the engine off allowed it to release.



    Hoped this helps.

Thank you for the opportunity. I have a Ford Escape 2001 6 cl and temperature gauge stocks on cold. Today it moves to hot then went to neutral and slowly went to cold again without moving.


Hi Ivette,

Temp sensor/sender units, ussually send a variable earth resistance dependent on temperature, so it sounds like the wiring is broken/rubbed through, causing the sporadic changes due to full earth going to gauge(hot). brocken wire(cold)

But could be a faulty sender just the same, doesnt sound like a thermostat after driving the gauge would still move in relation to engine temp, would start by checking the wiring to temp sensor, also check coolant level and monitor engine temp while driving if gauge is in-op.

Hope this helps.

My temperature gauge don't move and my check engine light does not come on


Bulb is possibly out behind the instrument cluster for the check engine light. As far as the temperature guage not working it sounds like your temperature sending unit is not working if it doesn't move at all. If your thermostat is stuck open it would come up some. If not your temperature sending unit is bad.

Honda Pilot 2003, low engine temperature, thermostat was replaced several times, still the engine temp is low.


use a termo laser to check temp of coolant at filler cap ,with cap off run vehicle till you have hot heat coming out of your heater then check with laser. if it reads above 140 then you know 2 things . either the therm sensor is going bad or the temp gauge is bad , make sure the radiator fans come on ,if they do and you have good heat then you have bad gauge.

Temperature gauge not working


Hi there,
My name is Steve. I can tell you that the barometric pressure sensor can, in no way, effect the temperature gauge operation. The gauge gets a signal from the engine computer which, in turn, gets a reading from the coolant temperature sensor. Your first step should be to have the check engine light diagnosed properly...starting with checking for codes. You likely have a code(s) relating to engine temperature or the temperature sensor circuit. Most common problems are erratic sensor operation and corrosion or oil contamination in the coolant temperature sensor connector. You will be time and money ahead by having a professional diagnose the problem correctly before deciding to buy any parts.

Engine coolant Temperature gauge fluctuates


Watch the temp gauge when the electric radiator fans come on. The temp sensor that controls when the fan comes on may be faulty.

Mini Cooper temperature gauge goes to red zone when idle


check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling leak.so replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

Check engine light comes on and then the temperature gauge goes up to hot


Mine did it too.... The problem is the Engine Power Relay.

The Engine Power Relay is in the relay box in the engine compartment. Aftermarket relay is cheap, but the original Ssangyong part will last many years longer.

Hope this helps.

2002 Honda Civic...The car is overheating randomly. Replaced the thermostat,and fan relays. Car runs fine and then randomly overheats with gauge going way up and then sometimes coming down.Overheating and...


RADIATOR COOLING FAN NOT RUNNING COULD BE BAD ENGINE.COOLANT TEMPERATURE SENSOR IS FAULTY IF COOLING FAN IS NOT TURNING ON AT SET TEMPERATURE OF 196 TO 203 DEGRESS.CHECK SEE COOLING FAN RUNNING WHEN ENGINE RUNNING HOT.IF YES FLUSH RADIATOR , FLUSH ENGINE BLOCK, HEATER CORE,REPLACE RADIATOR CAP.MAKE SURE YOU HAVE 50/50 ANTIFREEZE AND WATER IN THE COOLANT SYSTEM.CHECK WATER PUMP WEEP HOLE IF LEAKING REPLACE WATER PUMP. IF COOLANT FAN DONT TURN ON 196 TO 203 DEGREES, YOU HAVE FAULTY COOLING FAN,SHORT IN FAN WIRING OR ENGINE COOLANT TEMPERATURE SENSOR FAULTY.IGNITION TIMING WILL CAUSE ENGINE TO OVER HEAT.

Engine does not appear to be hot. Gauge says extreme heat


try replacing your temperature sending switch. That it what tells your gauge or idiot light where to read or light to come on. It may have a short in it. Or a short between the two.
