What does the DENSO 234-4333 fit?

It is a direct-fit downstream oxygen sensor for a range of Toyota, Lexus and Scion vehicles. Confirm your year, model and engine against DENSO's application list before ordering.

Is it upstream or downstream?

This part is the downstream sensor, mounted after the catalytic converter. Upstream sensors use different part numbers.

Do I need a special socket?

An oxygen sensor socket with a wire slot makes removal and installation easier, but it is not included. A standard wrench can work on some vehicles.

Is it better than a universal O2 sensor?

It plugs into the factory connector with no splicing, and DENSO supplies OE sensors. A universal sensor is cheaper but requires wire work and careful matching.

Will it fix my check-engine light?

If the code points to the downstream O2 sensor, replacing it often clears the light. Read the codes first, since other faults can trigger the same code.
