cel codes

[james3340]

I keep getting p0125 and a p0446 codes and I was wanting to know if anyone would know why I am getting these two codes. Thanks ahead of time guys.

p0446 Evaporative Emission Control System Vent Control Circuit Malfunction
Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.

Faulty vent valve
Open, short or excessive resistance on Vent valve control circuit
Blockage of vent valve
Bad PCM



p0125 is Insufficient Coolant Temperature For Closed Loop Fuel Control
the engine coolant temperature (ECT) sensor indicates that the engine has not reached the required temperature level to enter closed-loop operation within a specified amount of time after starting the engine.

Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Faulty coolant temperature sensor

I know they say don't say search, but if you want to know what a code means in the future, just type it into google and it will tell you what it is and likely causes. It will be much faster than asking on here

P0125 means closed loop temperature not reached. Three things could cause this code to pop up.
a. coolant temp sensor
b. thermostat
c. upstream o2 sensor.

i suggest to start small and replace the thermostat and coolant temp sensor. if you still get a code after replacing those then your best bet is your front o2 sensor.

As for your p0446 which means Evaporative Emission Control System Vent Control Circuit Malfunction.

a loose gas cap could cause this. if its not that then try replacing your EVAP purge valve.
