I was gone for training for a little over a month and I just got back to find out that my CEL and TRAC OFF light is on, also the trunk button doesnt work anymore, I press it and nothing happens. It's a 2001 ES300. It has been on since this past Saturday, 08JUL2006. I went to Autozone today to get the codes and they came up with:

P0441, P0446, P0300

When the guy was checking the codes, I noticed that there were 6 problems but some of the codes were mentioned twice (don't remember which ones, sorrry). I'm looking for guidance and advice on what to do, what these codes mean, and how much would it cost. Thanks.

According to the 2001 ES300 repair manual, the P0300 code indicates a random/multiple cylinder misfire, which could mean that one or more of your spark plugs are not firing correctly. When was the last time you got the spark plugs changed? They should be replaced every 90K miles. The P0441 code indicates an incorrect purge flow in the evaporative emission control system, and the P0446 code indicates a vent control malfunction in the evaporative emission control system. Both of these codes may mean that the fuel cap is not tightened correctly. Check the fuel cap rubber gasket also and see if there are no tears on the gasket itself.

 

Thanks Tammy and Lexusk8. I will check my fuel cap and tighten it. I bought the car used around November 2004, it's got almost 80k on it, and I don't know when the plugs were changed.
