How do I get rid of the po125 code on a mitsubishi montero sport 4wd?


Did you replace the thermostat. Low coolant temp means the T stat is stuck open.

WOULD A EGR VALVE CAUSE THE ENGINE RUN HOT?


Hi , Probably Not . Check the thermostat bulb position, and the coolant flow with the radiator . Check the oil pressure , flow and consistance ( viscosity an d cleanning) Good Luck

Check engine code P0125


PO125---- Insufficient Coolant Temperature for Closed Loop Fuel Control

No idea what car or engine you have

If you have a coolant temp sensor it could be bad

The thermostat also cool be stuck open

Both could be bad

Without the correct coolant temp (thermostat) or temp
sensor working, then your running the fuel injector timing
off Computer Controlled Open Loop-- meaning the oxygen
sensors are not in use as in closed loop & your wasting
gas ,as you have only a preset control over fuel trim eg:
no adjustment as you drive

I would install new spark plugs if over 3 years old -nothing
else,tune-ups are long gone 30 years ago,only the plugs left,
don't go done that road of being pitched something you don't need

I would new install front oxygen sensors,not the rear ones,
if over 100,000 miles
New thermostat & coolant temp sensor (CTS) if that
is what you have or other correction for that situtation.

Po125 code.... changed thermostate and etc sensor... Check engine light comes back on.... Whats next


The code means the coolant is not reaching a high enough temperature, or it is taking too long to reach the proper temperature. Check that the cooling fans are not running constantly and that the thermostat you installed is the right temperature.

Did you bleed the coolant system?This needs to be done,and it should be fine,but you will have to have the code erased too.

Check engine code po125 - 97 GP 3.8 - heater blows cold as engine temp rises to redline, then kicks in HOT and engine temp drops to normal... REPEAT. Is this the code for coolant temp sensor? Where is it...


What your describing is either a sticking thermostat, a low coolant condition or a blown cylinder head gasket.The code is for coolant temp fault.Not always the temp sensor but it is located next to the thermostat housing.

I have a 1999 mitsubishi eclipse when I am at complete stop my thermostat goes all the way up in the danger zone. i pulled over to a gas station no smoking no smelly coolant nothing. Do you think the...


Surely the thermostat is faulty. Fan only kicks in when sitting for 5 minutes or more. A plugged exhaust will cause overheating, but would be hot all the time. You thermostat should be changed and you should add 50/50 coolant

Shows trouble code PO125 coolant temp. to low. replaced thermostat.no change still shows same code after driving 35 miles.


I would have the OBD II scanner clear the codes. Then if the code still pops up, I would have the coolant temperature sensor looked at.

If you have changed out the parts and still get the codes you probably need to have the ECM reset. The dealer can do that for you or a repair shop that has the scan tool.
