The CEL light came on about half way to work this morning, and remained on the rest of the day. I dug out the reader and got a code of:
PO 442 01
The PO 442 shows in the manual as 'evaporative system leak, small'. No info on what the 01 part means.
I used the clear button, but the code immediately returns. I've removed, cleaned and re-seated the gas cap which caused the last such error several months ago.
Ideas on what else to check for? Or ways to find whatever leak there is without a trip to the dealer?
Thanks.
