Where can I get diagnostic instructions for code po456. 2011 Forester. Thanks

Looking for diagnosis instructions for code po456. Thanks.

Thanks general disorder for the help

General dissorder First, for any make and model car what are good scan tools. What do Home mechanics use Second. For problems with the tire pressure monitoring system on cars do you need a special tool or a scan tool can read the code. Lastly, the subscription services that you were referring to like all data and shop key. Are they for home mechanics or they are something only a shop would get. What do they cost. Thanks.

General disorder I have another question if you don’t mind. I really appreciate the help and info. What I wanted to know is who makes good scan tools for people doing their own car work. Does launch or autel make good scan tools. What else is good. Thanks for info

Lucky Texan thanks for help, info and reply.

How is innova scanner. Also I know autel is very popular. How are Launch Scan tools. Thanks.

Thanks. But what company actually makes a good scan tool for diy mechanics. Launch or Autel. What do you have. Thanks.

Who makes a good scan tool for diy mechanics. Thanks.

Thank you for the video.

What is code setting criteria for a specific code. I am sure they already checked it. Can someone please explain it to me. Thanks.

Lucky Texan Thanks for help and input.

Bottom line is : my mechanic with looking at all the scan tool data he found no reason for the po456 code. He found no other codes or pending codes. The light is off so if it comes back then he will do further testing.

Gd No pending codes or codes stored. Now that the code is clear maybe it won’t come back on. Just asking if you clear a code if their was a problem when my mechanic drove the car around wouldn't the code come back. He said normally if their is a problem when you shut the cel off and drive around the light will come back. Also what is code setting criteria because I am sure they already looked at that. Thanks.

General disorder Thanks for the help and input.

Thanks. It did answer my question. Yes I did take it to my mechanic for check engine light. Code po 456. Evap small leak. He cleared the code and drove the car around for awhile. The code never came back. He said usually if their is a problem when code is cleared driving around it would of came back. He also Looked at all other scan tool data and screens related to car and code. My mechanic sees no reason why check engine light came on with the cruise control light flashing and the traction control light on. He also has a smoke machine to check for leaks. He said based on scan tool data and the light has not come back on when he was driving around he feels that he does not want to do a smoke test now. He said if light comes back on bring car back and he will do further testing maybe use smoke machine. But as of now. With his testing he has no explanation of why the check engine light went on. Thanks.

Po 456. Small evap leak. Already tried new gas cap did not work.

So to answer my question: if you use a certain brand of gas and your car does not like it or if you over fill your tank will it cause a check engine light. Thanks.

So overfilling gas tank can give a check engine light also I heard that if you keep over filling tank the charcoal canister will get wet and then you will need a new one Thanks

What I wanted to know is when you are filling your vehicle with gas and the pump automatically shuts off If you keep filling your tank with gas meaning over filling tank is that bad for your vehicle Also what does it do to your vehicle Could it give you a check engine light Thanks

General disorder I was just curious if you are a mechanic. Thank.

I totally agree I am not a mechanic. My car has po 456 one thing it could be is the gas cap. I already tried that and it did not work. Another thing it could be is a small hole in a evap hose. I do not know if that is it I am just taking a guess. Also it could be rust. If it is rust where would the rust be. Another thing what is the most common problem with this po 456 code I do not know I have an appointment with my mechanic tomorrow to see what the problem is I am in 100% agreement that I need to use a smoke machine to fine the leak Since I don’t have one or know how to use one that is why my vehicle is going to mechanic tomorrow Thanks

My 2011 Forester has cel. The code is po 456 small evap system leak. It’s not the gas cap all ready tried that. It’s probably a evap hose that has a small hole. I just can’t find evap hoses or charcoal canister. It goes to my own mechanic tomorrow. I could be wrong but I feel like Subaru vehicles are very hard to work on. Every thing in the vehicle is hard to find. I feel they don’t want people working on the vehicle only Subaru mechanics. I have a Toyota and everything is much easier. Thanks.

I wanted to know where the charcoal canister is located on a 2011 Subaru Forester. Thanks.

Lucky Texan great video. I did not know it was that time consuming to replace the spark plugs. Also now I know where they are located. Thanks.
