Obd code p0440 p0452

[2002sunfir3]

Hi again,

Engine light came on a 2002 sunfire. Took it to a mechanic to read the code, P0440 P0452. He said it only means the gas cap tank wasn't connected and not to worry about it. Gas pump ended up failing while driving on the highway. Had the gas pump and lines replaced after a tow by another mechanic. Engine light got reset after this. Came back on again.

I'm wondering what the code is. Haven't had it read yet since reset a few days ago, but I'm assuming it's the same two codes.

Car's got 198k, and get's all regular service.

any ideas?

Thanks

the P0440 and P0452 have a number of causes
