ok so i got in the D to run to the store real quick and as im pulling out of my driveway the CEL pops on, so of course i figure its an evap code, some idiot at the gas station didnt put the gas cap back on tight enough, i run to the store, come back put the obdII scanner on it and pull a P0137 code (o2 sensor voltage low bank 1 sensor2)

^ from the cel sticky in here

now my question is could this simply be caused by water somehow getting in there?? i mean the truck has been sitting all weekend and it has been raining non-stop for the past 2 weeks except for a few hours yesterday,

p.s. i cleared the code, and if it come back on i will be looking to replace the sensor and check all the wires going to the sensor

 

I would clear it once and if it comes back, replace the downstream. It is possible that when it rains, water can get in the connector and cause this code. (Happens all the time in the LX cars) But yeah, clear it once and then change the sensor... Cheap and easy fix... O2 sensor codes seem to come on more in the rain.... Hmmm....

 

It's called humidity..... This is why the O2 likes to come on. More O2 in the air than normal.

Check the wire connections on that code.

 

yea i did check the connections, i also cleared it and it hasnt come back on, and my drive home from work this afternoon took me through the flooded streets of paterson (anybody from jersey will know what that must have been like) and it didnt come back on, i was one of teh few people in cars that were able to keep moving through that (yes i feared for my life i was in downtown paterson w/o a cc permit or any type of self defense)

 

Get that permit before Obama takes em out.
