Just found out that I need to replace my front oxygen sensor, does anyone know exactly where it is, and if its eazy to do on your own?

 

should be easy to do it yourself. there is one in the front, and one in the bottom. they are screwed in to the exhaust pipe. from the o2 sensor, trace it back on the wire, disconnect the wire, then replace with a new sensor.

 

When you get underneath the car, you will see a green wire connected to the collector pipe just before the catalytic converter. This green wire goes up to toward the firewall and is clipped into a black metal bracket. You will have to trace this wire toward the top of the engine to locate the harness and unplug it. Once you plugged it, unscrew the sensor out of the exhaust pipe.

Take new sensor, screw it into the exhaust pipe, connect harness, clip into the metal bracket. Done.

 

Thanks a lot for the tip guys! Now i see there is a universal sensor and one specifically for the 2001 TL, how hard is it install a universal one and does the brand matter for this part?

 

Get the OEM part
