Part Details
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.

Disconnect the negative terminal on the battery. Use an 8-millimeter wrench, and wiggle the terminal off. Put that to the side. All the O2 sensors are replaced the same way. I'm gonna show you on this one because this is the easiest to access. Disconnect the connector. Just a little tab, just push down on the tab, and just slide it out. For some of the other O2 sensors, it may be easier to use a socket, an O2 sensor socket. Slides over, so you get the wires out there, or even this style. Or you can use a 7/8 wrench or a 22-millimeter wrench, and just loosen it up, and slide it out. Take the new O2 sensor, get that thread started by hand. And get a torque wrench on there, if you can, and torque that to 35 foot-pounds. And plug it in. Lock it in place. Connect the negative battery cable and tighten down the cable. Just snug it up and make sure it's not loose.

The downstream O2 sensor is located right here and there's also one on the back located right there. So we're gonna replace this one. Disconnect the connector, push down on the tab, and slide the connector out just like that. There's the tab. Now I'm gonna use an O2 sensor socket. This is a 7/8 and it's got a slot in it for the wire. Slide that on, take it off, slide that out. Take the new O2 sensor, and just start it by hand. That's good. And then we'll tighten this up. And I'm gonna torque this to 35 foot-pounds. Then take the connector and connect it, lock it in place.
