SOURCE: HAVE A CODE PO446 1999

P0446 is an evap code. Most likely, you need to change the charcoal canister vent valve (CCV) under the trunk floor. Fuel cap codes set 3 codes at once, P0440. P0441 and P0446, all at the same time.

sets below the intake manifold and takes about 5 hours to replace even if you are handy with cars it is a big job to take on.after doing over 50 or more for an old recall it still takes me about 2 hours to complete.

When a repair shop performs the maintenence, they should be able to reset it for you. usually you have to hold the trip reset in and then turn the key on, keep holding the button until it resets.

SOURCE: jeep liberty starter sticking in cold weather

Generally I have seen this happen when water gets into the starter and freezes overnight. When you first try to start it, the starter won't work correctly but heat generated while it's stuck will quickly melt the ice and then it works. Only way I know of to eliminate it is to remove the starter and use grease on all the moving parts that connect the solenoid to the starter Bendix drive. Not sure why, but it seems to happen on some starters but not all, even on identical vehicles. I have corrected the problem on many customers cars by greasing but have left mine alone and actually never had a problem other than the initial "being stuck" in the AM. If your starter is very old, you could replace it but that is up to you.

Starter isnt engaging when turn key but lady said she turned on lights just trying anything to see if it did anything car started starter engaged?


Just guessing, but try checking the battery connections and the battery! It sounds like it was cold. I believe the ECU will keep it from starting if the voltage from the battery is low. Turning on the lights warmed up the battery a little and increased its terminal voltage. I have seen similar things in the past. Pops always turned on the lights for a minute when starting in cold weather.

You could be right, it may not be the battery, but something to consider.
In cold weather the damand on the battery to turn and start the engine is much higher than in warm weather.

Often people buy a replacement battery without knowing what the minimum, "cold cranking amps," rating is for their car. And often there's no sign of any problem. But, when the weather turns cold not having the minimum cold cranking amps is now a problem.

Just as a procautionary measure, you could read the cold cranking amps rating on your battery, and then call any parts store to see what battery is called for as a replacement. This could prove very helpful.

Something else that may be helpful to you.

1. You could check on your battery to see if it is a maintenance free battery.
If it's not maintenance free, you should have the levels in your battery checked. If the levels are low it will prevent the alternator from charging the battery up to its peak level.

I hope this helps.

Hi ohionow08,

No doubt a cold weather snap can kill a battery faster than anything! I see your battery voltage is 13.68 volts, but is that under a load or is that static voltage? If this only started after you disconnected the negative cable, I would suggest first that you remove that cable again from the battery, remove the 5mm bolt from the cable and insulation completely and check for corrosion inside the insulation and on the bolt itself. If you find corrosion, clean everything well with a wire brush. It may help to make a solution of baking soda and water in a spray bottle and use it to help break up and corrosion deposits. Reinstall everything and check the other end of the ground to make sure there is no corrosion there.

If these things check out ok and then you may want to consider having the battery load tested. Most auto parts stores will offer this service for free as a tool to get customers into their stores.

I have a 1992 toyota 4wd 3l that has been starting really hard especially on cold mornings. i cleaned the cold start injector and changed the timmer but it still does it. can anyone help? thanks rick


Check your battery for proper volts (12.6). Sometimes the cold weather will bring a battery down. Also check the Starter Relay, again cold weather will make it stick causing it not to start. Those are the biggest problems with a car not starting in the cold weather unless you have something else going on then your starter and your ignition needs to be checked.

BMW 325xi; 160k; check engine light on-->next day, wont start!


I would try to jump it to see if the starter engages and the engine runs, if it does you have a connection problem between the engine starter and the battery, if it does the same thing with cables then you will probably have to tow it in to the shop. I do not think your problem is related to cold weather, but it could very well be related to the check engine light. Exactly what the check engine light is on for I can not say with out a code, but I agree with your thinking about taking it to the shop. Hope this helps, let me know.
