TRQ oxygen sensors are manufactured to precise specifications using premium raw materials to optimize your vehicle’s emission system. Each sensor is isostatically-pressed for improved strength and durability, and plasma-sprayed to improve sensitivity and prolong the service life of the sensors. Oxygen sensors wear out over time and should be replaced every 60,000 miles to prevent poor engine performance. TRQ recommends replacing the oxygen sensors in sets to optimize fuel economy and reduce overall emissions. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.

How to Replace O2 Sensor 2003-14 Chevy Tahoe
How to Replace O2 Oxygen Sensor 2006-10 Pontiac G6
Created on:
Tools used
O2 Sensor Socket
Straight Cutters
Ratchet
7/8 Inch Wrench
Trim Tool Set
The O2 sensors are located right here on the exhaust. This one is in front of the converter. And then there's another one in front of this converter. These are the two upstream O2 sensors and then the downstream after the catalytic converter, there's one on the right side, and there's one on the left side. And the procedure to replace these is the same for all of those. Connector is right there, there may be a lock on the connector, you might have to pull that out and then just disconnect the connector, just like that. Then there's a retainer that holds the connector on, just use a trim tool and take that retainer off. Or you might have to cut it, the new one has one. I'll just cut this one off. And just pull that through. And take a 7/8 wrench or you can use a O2 sensor-specific wrench or even a socket and loosen it up, and just loosen that up. And take that out. I'll take the new O2 sensor and get it started. Start it by hand. Then you can tighten this O2 sensor. And do the best you can, if you can fit a torque wrench in there, you wanna tighten that to 31 foot-pounds. And resecure the connector into the retainer. And connect the connector. And then if you have that lock, put that lock through, and then you can do the same with the other O2 sensors.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to replace the upstream oxygen sensor. Now that's the one that's before the catalytic converter. It's between the motor and the catalytic converter. This is a 2007 G6 with the 4 cylinder motor, same as any G6 or Saturn Aura. The only tool you'll need is a 7/8 inch, oxygen sensor socket and a flexible headed ratchet will make the job easier.
Access your upstream oxygen sensor. It's right in behind the engine. This is a 2.4 liter, 4 cylinder. There's the oxygen sensor. There's the electrical connector. Now back in, there's a blue, little safety lanyard that you need to pull out. Then, there's just a tab on top of the connector, pull it up with your thumb and then you should be able to pull the connector right off. Now grab the other end, the end that's connected to the O2 sensor and pull it out of the clip. This is the tool that makes all the difference. It's an O2 socket. See it has a big slot in it that allows the electrical connector to go out to the side and then you put the socket around the oxygen sensor. A flexible headed ratchet like this is going to be your best bet, allows you to get the most leverage. Once you get the ratchet on there, turn the O2 sensor out and actually, this one comes out fairly easily once we get it started.
The new sensor goes in, just opposite of how the old one came out. Put it in place, get it in the hole and you can usually start it in by hand. Then, once you get it fairly tightened up, then make it nice and tight with the socket. Now, obviously, we need to reconnect the oxygen sensor. I'm just going a little fast, here, because doing it with one hand, makes it a little more difficult, but reconnect the connector. Make sure you put that locking clip back into place. Then clip the connector back into the bracket.

Upstream. If you click where it says 'vehicle fit' it lists upstream or downstream as a part of the fitment.
