Anybody else have troubles with the check engine coming on. P0137 Replaced this O2 sensor less than a year ago with OEM sensor.Was ok for awhile. Now it keeps coming on after I clear the code.:smiledown:

A code P0137 may mean that one or more of the following has happened:

Faulty o2 sensor Exhaust leak near the rear sensor
Plugged catalyst
Short to voltage on O2 signal circuit
High resistance or open on O2 signal circuit

It is very likely your catalytic converter is clogged. The sensor may never have been faulty to begin with. This is a VERY common with mistake. Just because the sensor throws a code doesn't mean that sensor is bad, it can also mean something is causing it to read bad.

How many miles on the truck? if over 100,000 miles it is likely a clogged cat. They are expensive.

hm well with that mileage I'd tend to think it's not a cat but you never know. I guess the first thing to do would be verify the harness isn't cut or frayed or anything.

I have been having that issue everytime I hit a nasty bump the check engine light would come on.....I unplugged all the sensors and cleaned all of the connections and did not have the light come back on for a few months. The other day it just turned on again when I was leaving the driveway. Bought a new sensor today and going to put it in tomorrow to see if that does anything.

I'd bet yours has a rubbed through harness somewhere.
