Brought my catalytic converter below the engine maintenance gauge [efficiency] threshold.

This oxygen sensor was purchased for a 2010 Toyota Sienna. I had a P0137 O2 Sensor Circuit Low Bank 1 Sensor 2. The sensor that was in the car was a cheaper aftermarket sensor and was biased to output a low voltage. Spend a few bucks more and stick with Denso. This comes with an anti-seize already on the threads, a harness retainer on the harness and a grommet that goes through the floor pan.

The engine code came in with 107,000 miles and I had no hesitation in dropping the part for just $50 for the component and $10 for the custom socket (also bought) repair ). to Raven).

If you first pull the mains plug near the driver's foot and position the tool and new part correctly (I only needed a PB Blaster spray can, ratchet, 22mm sensor socket and new part), you can replace it in just one trip under…

Had code P0420 for a few years but when I cleared the code it went away for weeks before coming back. It didn't seem to cause any problems so we just went with it as I really didn't want to try to get to bank 1 sensor 2 oxygen sensors assuming they would be hard to get to and expensive to replace.
