What's up fellas,

The other night I was driving at a steady 50-60mph and the engine check light came on, so This morning I went to Autozone and got the codes

P0136 and 137
Bank 1 02 Sensor..

Is this a serious problem? Anybody know any info about this?

Only mod I have on the car is Borla exhaust which has been on since I bought her about a year ago.

Any infomation towards this would be helpfull. Tommorow I might go to honda and see what they say. I had the guy Turn the light off and It hasn't got back on.

Thanks!

P0137 is a "low voltage" indication for the secondary O2 sensor (in the cat). This is not a critical sensor to run the engine. It only monitors cat function. It's telling you that there is insufficient electrical current flow in and out of the sensor. This could be the wiring, the sensor or some intermittent issue. If the CEL doesn't come on again, it's not a big deal. Even if it does come back with the same code, it's not a big deal except for the light being a nuisance and a camouflage for other codes.
