Does anyone know what these codes mean, and if they could be potentialy damaging to my engine. Thanks

It's either your secondary o2 has taken a shit

or your catalytic converter has taken a shit




..replace secondary o2, if that fails, then your cat is fucked, get a race header and defouler :)



and no, they will not have an effect on your engine

P0137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)

P0420 Catalyst System Efficiency Below Threshold (Bank 1)
What, exactly do these mean? I already have a race header w/ a welded-on cat, but ive had it for almost a year already. Why would the light just barely come on?

Thanks for help guys!

I already told you in my first post.

Your secondary o2 sensor is dead, and your cat is probably dead

replace o2 to see if cat is still working
