Sensors

If you are concerned about whether the generic part will work, why not return it and buy the correct part instead?

 

If you are referring to the sensor upstream from the catalytic converter, that is an air/fuel ratio sensor and if you actually bought an oxygen sensor, that part will not work at all.

If you are referring to the sensor downstream from the catalytic converter, then it shouldn't matter as long as you can figure out how to wire the sensor to the wiring harness.

 

The job of the downstream oxygen sensor is to report the effectiveness of the catalytic converter to the engine ECU. It doesn't really impact air/fuel mixture, which is the job of the upstream air/fuel ratio sensor.

do you know if Denso is the OEM for the Toyota 02 sensors? Working on an 07
Have you ever replaced with Denso instead of the Toyota brand in their box?

 

I'm not Patrick, but yes Denso is the OEM for some (ok, a lot of) Toyota parts, including tihe O2 sensors.

I don't know if Patrick has used Denso boxed rather than Toyota boxed parts, but others here have, some of whom are professional mechanics.

The key thing when using non-OEM (and even Toyota branded, in fact) is to ensure the parts are genuine and not counterfeit. Price can be an indicator, but not necessarily a definitive one. Prices one-fifth to one-tenth, or even half the price, of the OEM are not likely to be genuine.
