Code 0031, 0037, 0107

[Payback45]

How do i fix these codes from coming up? 0107 doesnt come up that often but as soon as I clear 0031 and 0037 they come back as soon as I start the car again.

P0037 Rear heated oxygen sensor heater control circuit low (Bank 1)

P0031 Front heated oxygen sensor heater control circuit low (Bank 1)

P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

You need new O2 sensors. Their heater circuits aren't operational.
Have you done anything recently to the car that may have damaged them?

[Payback45]

My most recent mod was the hella horns but the codes were on before that. Where is a good place to get new O2 sensors?

Does anyone have part numbers?

[Payback45]

I called Napa and asked if they had O2 sensors and they wanted to know if I had a Wideband AF Sensor? Do I?

[Huffer]

You don't have a wideband... you want stock sensors. Buy Subaru sensors.

[Grafton]

yeah get them from the stealership then you wont have headaches with bad ones outta the box

what about code 0107?

Check the vacuum hoses and the wiring leading up to your pressure sensor. It could be the sensor itself is bad too.
