Hi All,

Purchased my first Camry ( oct 2018 )
it is a 2012 XLE V6 170,000 kms
anyway, i have check engine light on, and error codes are as follows:

P0057 came on around christmas time, and i replaced bank 2/sensor 2 with a new one, and problem solved.
3 weeks later check engine light back on with codes P0057 again and also P0100
i have been resetting and it would go away for 2-3 days at a time and back on, with the same 2 codes.
now i have replaced the mass air flow sensor, and still the problem persists .

has anyone seen this problem before? and if so, any ideas what might be my problem.
other than the check engine light being on, car appears to work fine, maybe a little harder on gas than usual .

any help is appreciated
Cheers

 

Did you replace the second sensor on the cylinder exhaust closest to the radiator?

What brand of part did you use, Toyota, Denso, etc?

Do you have a scanner that can read out real time voltages on the sensor and MAF?

Check wiring from the sensors to the computer. Both MAF and 02 sensor wiring runs through the EFI relay box, could there be a problem here?

Bad computer can cause issues.
