2002 4cyl CEL codes

[7luvr]

Hey guys

The wifes camry all of a sudden tossed up CEL. Codes read P0100, P0110, and P0420. Car has about 125K miles, runs fine. I cleaned the MAF sensor with CRC cleaner just for that, pulled EFI fuse to reset, came back on immediately when started.
I was thinking of getting a used one from pull-a-part, but they only have 98 camrys at the moment. Any chance MAF is the same? Open to any other ideas (before spending $$ on new MAF) that you guys may have.

I had no success pulling the EFI fuse to reset my 02, always had to use the battery. Are all the codes there after you reset? I would doubt a Po420 would reappear immediately, that code triggers based on emissions gathered over a period of time. Could back up the battery/EFI fuse argument. The fact that the P0100, P0110 codes are both on the intake but different sensors would make me curious if the intake came loose, has a hole, filter clips dislodged, or a vacuum hose fell off.

Thanks, I'll try the battery. Gotta remember to write down all wifes radio pre-sets or I'll catch the devil. I thought it could be a loose connection too...I looked everywhere and even reseated the air filter, no luck. Hosses seem in good shape.

you might need to have the ecu calibration reset and you might need a converter sorry.
