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.

Tools used
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.
