#537 of 713 O2 sensor location on 2004 Colorado
Dec 29, 2010 (8:44 am)
Can anyone please tell me the location of the O2 sensor for a 2004 Colorado? My engine light came on and a local mechanic tells me that it's the O2 sensor. I would like to buy one and replace it myself, but don't know where to look on the truck. Is there more than one O2 sensor?

How did your mechanic determine that the 02 sensor was at fault? If it was just from reading a trouble code, you may be throwing money away here, since the scanner does not tell us which component is bad, only which system or circuit is reacting in a deficient manner. Many an 02 sensor that is perfectly fine ends up in the trash bin these days, along with frustrated owners. The only way to know if an o2 sensor is bad is to test it individually for proper voltage values. A 02 code could actually be about many other things not related to a bad 02 sensor.
If he tested it properly for you by getting under the car and applying a meter to the sensor, then okay.

Thank you for the response and no he didn't get under the truck. I believe it was just a code from an engine light reading. I would hate to throw money away and have the light still on. Is there any visual way to inspect an O2 sensor without damaging it?

You mean by looking at it? No, I don't think so. You have to test it with a volt meter. I mean, it might be a good *guess*, just from reading the code, but chances are even up that won't cure your problem.

I own an 05 2.8L manual with 102,200 miles which could have been part of the valve seat recall. First I will say that I have enjoyed the truck...and still do? I like the looks of these Colorados and the truck ran pretty strong for a while, but now I am having an issue which I really hope is not that valve seat problem...I have burned out somewhere in the neighborhood of 8 taillights, headlights, or brake lights. Once the truck shook violently and stalled while the traction control engaged while driving in snow...took it to the dealer and they said everything was fine. The front end on my truck shakes like an SOB while I'm driving between 50 and 70. I put H3 rims with 265/70/16s on it so I initially attributed it to the tires but I think they may have just accentuated the problem with the front end. I have had a ton of codes pop up since I have owned it and I have had the codes pulled at Autozone each time, and tried to diagnose the problem with their info...Once they recommended I buy a new gas cap because there was a pressure problem, etc. Also I was once told to change the cam position sensor...did that and nothing changed...so I did a tune up...changed the plugs, front o2 sensor, air filter, fuel filter, differential fluid, etc. that helped but at about 90,000 miles the truck was idling terribly and started stalling on me when I slowed down or came to a sudden stop...did that about 6 or 7 times while I was out of town one weekend...so I researched and found that cleaning the mass air flow sensor and throttle body might help that...wow did it ever! Cleaning those components pepped up the truck in a big way...I was pretty pleased with how strong it was pulling so I figured no way I was gonna be one of those valve seat trucks...Well around 98K my clutch pedal starts feeling weird as if the hydraulics in the pedal are trashed...but it still worked ok...bled the clutch line and well it may have helped some maybe...still having that problem...then about a week and a half ago during a cold spell, I start her up and the damn thing is idling like a diesel and I'm hearing clicking up front...well I was hoping this was something with the water pump, power steering pump, pulleys or something, but It has gotten worse and it hasn't thrown any codes in about 12k. And on top of this, my blower will now only work on high...so I have a wiring or connection problem. I've been looking into these problems and I think the best case scenario for my engine noise is gonna be a timing chain tensioner, which I may be able to handle or afford. I would like to fix this truck up a little bit and try to put a ton of miles on it but wow at 100K like clockwork the damn thing is trying to clean my wallet! I'm not bitter because the truck was cheap and every vehicle is going to have problems, but damn the head issue and well if I end up getting the motor squared away and put new tires on it with an alignment, it better straighten up! Going to talk to my mechanic friend on Friday for him to hear it...After that, maybe I'm gonna swing by the dealership to see if they can help with this...help being financial help...as in discounted fix? Also added to the list of problems...my rear window leaks pretty bad when it rains...I think it screwed up my amp and speakers...

Talked to my mechanic, going to be looking at the timing chain and tensioner and the lifters...planning on a DIY...starting 2011 with a nice little project...happy new year...looking forward to redlining this thing a few times after I get it right...lol...One last comment before the project starts...thinking about many posts I've seen bashing the truck and GM...there is always that thing about buying American...and being able to find parts...I believe this is going to hold true...

I had engine ticking on my 05 Colorado, as well as many of the other problems you mention. Head and valves were replaced under GM special warranty. Dealer advised me that the ticking noise was caused by a cracked manifold, which GM would not cover under the special warranty. The ticking is gone, but I poured $500+ more into my black hole.
As far as buying American and accepting that all vehicles have some problems...JD Powers ranked the Colorado (#2) and Canyon (#?) among the top 7 worst vehicles made in 2010 so it's reasonable to assume there's more than a handful of Colorado problems. My mileage is still under 100K, and the defects I've experienced are unacceptable and too long to list. At least other unsuspecting GM loyalists won't have to worry about buying a Colorado, as I heard GM is bailing on this truck. Apparently, I've been a loyal GM customer for too long and it's time to consider bailing on blind loyalty.

Problem is fixed....thanks for the responses. I installed a new front O2 sensor and took off my throttle body and totally cleaned it with throttle body cleaner. I also took out my MAF sensor and cleaned it with MAF sensor spray. The engine light went off and the truck is running like it is brand new again. It's very responsive when touching the gas. I highly recommend doing this simple 1 hour maintenance tip to anyone with a sluggish Colorado.
Happy New Year everyone!
