Kevin C :

Welcome to Pearl.com, I'm Kevin and I'm here to help resolve your Automotive issue.Hello,how may I help you regarding your Forester?

Expert:  Kevin C. replied 4 years ago.
First thing we need to do is access what codes are in the computer. Whenever the Check Engine light illuminates, there will be a corresponding code. You will need a code reader or go to an auto store, they will read your codes foryou.
Customer: replied 4 years ago.

CODES: PO102, PO103, PO700, PO731.

Kevin, Subaru is a 2009.

Expert:  Kevin C. replied 4 years ago.

First thing I would check are the connections on the passenger side of the car..at the air cleaner , right behind the headlight area, there should be an air flow meter , a lot of times people forget to reconnect that after doing plugs. P0102 and 103 are air flow meter codes and will trigger the ATF codes too (P0700 & P0703) Let me know.

Connection is good to the air box.


 

Expert:  Kevin C. replied 4 years ago.

Ok, so the air flow meter is connected.

Did you do anything else to the car? Try clearing the memory?

Air flow meter codes are fairly direct, if the Air flow meter is connected and the harness is ok, and if the code comes back after clearing the memory, you may have a damaged air flow meter.

Customer: replied 4 years ago.

I cleared the codes and came back on a test drive.

Expert:  Kevin C. replied 4 years ago.

If the car was running well before the plugs were installed, the air flow meter may have been contaminated since all connections are good and there are no other leaks.. The air cleaner at the throttle body is on tight and all connections are good as well?

If so, you need a Mass Air Flow Meter.

Customer: replied 4 years ago.

OK. all connections are good. can I clean it with Mass Air cleaner?


 

Expert:  Kevin C. replied 4 years ago.

You can try that but it hasn't been real successful with Subaru Air Flow Meters.

Customer: replied 4 years ago.

OK. I calling the dealer for the part.

Customer: replied 4 years ago.

Is there a way to ohm out the sensor?

Customer: replied 4 years ago.

I can borrow a scanner, not sure if I can get a Subaru key.

Expert:  Kevin C. replied 4 years ago.
Any decent scanner that can read data should work, let me know.
