It should, because it's telling you something is wrong. Not spending $75 could lead to spending three times as much down the road, where you'll really be bitching.
Treat your truck right and don't be cheap.

Thats correct. That code is for the o2 sensor after the cat. i have the same code. the light just doesn't bother me enought to spend $75 on the new sensor

I've got a persistent P0138 code which means oxygen sensor 2 in bank 1 is too high--does that mean the after-cat sensor? My pre-cat sensor is only 5 months old and it's a dealer piece--surely it isn't going bad yet, right? The fact that it says bank 1 suggests that perhaps there's a sensor on each bank? I haven't crawled under there to have a look, but I'm doing an oil change today and I'll see.

So your saying, fix something that only tells you that the cat is not efficant. Or it will not be good on the truck. Funny thing is is that my fathers truck has had the same code since about 60,000 miles. he now has 295,000 on it and guess what, lights still on and no problems. so thats why i say its not a needed fix. I dont see why fixing it will better, or if not fixed, worsen the truck.

i thought that only the 1st o2 sensor was for the fuel mixture. [sm=confused06.gif]

O2 values and trims are ignored during open loop mode. The ECU uses a preset amount of fuel, ignoring any trim corrections. O2 Volts will not cycle in open loop mode.

RE: o2 sensor
yall say it wont hurt the truck just cause the c/e light is on.. that may be.. it DOES affect your fuel consumption.. its there for a reason... the other concern would be this.. what happens when something ELSE goes wrong with the truck.. and it throws a code... you wont even know it threw a code.. the light is already on.. lotta good thats gonna do.. it defeats the whole purpose of having a c/e light ... FIX IT
