SOURCE: service engine soon light came on.

That is an EVAP code. its a vent control code. you can manually test it by powering it up if you know where its at. i cant remember exaclty where its at off the top of my head but its only 2 wires. using a volt meter you want to make sure power is getting to it, but you cannot activate it without dealer scan tool.hmmm if you can figure out which is ground and power when you give it 12 volts it should click. meaning your vent solenoid works and you have wiring problems or its leaking.

EVAP problems are hard to finde with out scanners. you can change the vent solenoid and hope it fixes it. but a code points you to the direction of a problem. hopefull its not wiring problems. in the northern states with snow. ice can pull out wires and also get clogged in the vent solenoid and lock it up. its either wiring or bad or a leaking solenoid. check condition of wires. if they look good try a vent soleniod.

if that doesnt fix it after a engine light reset and 2 weeks or so. then goto dealer. you need to reset it after repair. light will not go off on its own.GOOD LUCK

SOURCE: emission control system malfunction code po446

Code p0446 is for EVAP vent valve performance. Unfortionly there isn't just one item that can cause this code and the test require the use of a scanner. You can do a visual check but other then that with out scanner its just going to be replace and hope. That could wind up being exspensive. 1116f81.png

My service engine light is on and the code is PO446 with the emission system (Advance Auto confirmed the code). What do I need to replace to repair this problem?


What engine? it could be a bad gas cap, thats about all you can check, a repair shop will need to go deeper to diagnose.

Check engine come on code po446 hoow u that?


The "check engine" warning light advises that the vehicle is in "fail safe" mode. That means only some of the car's capabilities are operational, just enough to get you to the nearest service point. You probably should not drive it any further than that. Have your service man download and analize the fault codes from the ECM which will indicate what the problem code is.

if the air filter was recently inspected or changed, look for the vacuum hose to be disconnected from the valve located on the air filter cover. another source may be the gas cap either loose or with the tether strap caught under it preventing a proper seal
