Car - Mitsubishi, how to reset temperature gauge?

if the car is still over heating then check the fan and see if the fan is kicking in.

Also most of the new cars after replacing the thermostat, you need to clear the fault with a computer as they get stored on the system and will not clear from dash. Even though you have replaced several parts and everything is working fine. system will need to cleared.

Check the battery

I may b a fuse in the engine fuse box labeled gauges..check those and all other fuses pertaining to dash lights.. If they are good then it may be your wireing in the dash itself..or plugin wire to the dash may b faulty

Get a voltmeter or take your battery in to a shop and have it tested to see if it is putting out too much voltage. Sometimes when you take the negative cable off the battery to reset codes, the car has to be started and ran a short distance for a handful of times in order for the computer to reset itself.

If all voltages checked ok, then most probably its faulty instrument cluster board on which gauges are connected. Yes if cluster circuit board looks ok, then also it can be faulty. Somewhere there is minute short or burn on board then such problem arises.

Also check the fuse box. One under hood and other under dash.

Inspect each and every fuse and see if all are fine or not.

These details will help.

Thanks.

check for the alternator failure. probably not charging.

change out the water pump that should solve your problem for over heating.

Hi again,

Did the negative battery terminal removal able to reset the instrument CPU?

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

my heat gauge keeps registering hot but the car is not running hot the dealership can not figure it out they have replaced the sensor and thermastat

1st check the #4 fuse (10A) and #10 fuse (7.5A) on the 'under-dash' fuse block.
then #9 fuse (10A) on the 'engine bay' fuse block.

if the fuses are good, the gauge assembly has has "self-diagnostic" feature.

Self-diagnostic Procedure

The gauge assembly has a self-diagnosis function.
. The beeper drive circuit check
. The indicator drive circuit check
. The LCD segments check
. The gauges drive circuit check (speedometer, tachometer, fuel gauge, coolant temperature gauge)
. The communication line check (the coolant temperature signal line between the gauge and ECM/PCM)


Entering the Self-diagnosis Function:
1. Push and hold the trip/reset button.
2. Turn the lighting switch ON.
3. Turn the ignition switch ON (ll).
4. Within 5 sec., turn the lighting switch OFF, then ON and OFF again.
5. Within 5 sec., release the trip/reset button, then push and release the button four times repeatedly.

NOTE:
. While in the self-diagnosis mode, the dash lights brightness controller operates normally.
. While in the self-diagnosis mode, the trip/reset button is used to start the beeper drive circuit test and the gauge drive circuit check.
. lf the vehicle speed exceeds 1.2 mph (2 km/h) or the ignition switch is turned OFF, the self-diagnosis mode ends.

The Beeper Drive Circuit Check:
When entering the self-diagnosis mode, the beeper sounds five times.

The Indicator Drive Circuit Check:
When entering the self-diagnosis mode. the indicators lights (such as: Seat belt indicator light, Door/hatch indicator light, Brake system light. Charging system light, Low fuel indicator light, maintenance required light) blink.

The LCD Segment Check:
When entering the self-diagnosis mode, the odo/trip segment blinks five times.

The Gauge Drive Circuit Check:
When entering the self-diagnosis mode, the speedometer, the tachometer, the fuel gauge, and the coolant
temperature gauge needles go from the minimum position to maximum position, then return to the minimum position.
NOTE:
After the beeper stops sounding and the gauge needles return to the minimum position, pushing the trip/reset button, starts the beeper drive circuit check {one beep), and the gauge drive circuit check again.
The check cannot be started until the gauge needles return to the minimum position.

The Communication Line Gheck:
In the seif-diagnosis mode, after the odo/trip LCD segments check, the self-diagnosis starts the communication line check.
lf all segments comes on, the communication line is OK.
lf the word" Error" is indicated, there is a malfunction in the communication line between the gauge assembly, the multiplex control unit, and the ECM/PCM,

Ending the Self-diagnosis Function:
Turn the ignition switch OFF.

Note: lf the vehicle speed exceeds 1 .2 mph (2 km/h), the self-diagnosis function ends.

If everything works correctly during the check, check your VSS (vehicle speed sensor)
