- Does it fit my car?
- It is a direct-fit sensor for specific Toyota, Lexus and Scion models and years. Check your vehicle's year, engine and sensor position against Denso's application list before ordering.
- Is it upstream or downstream?
- This part is used as an upstream (pre-catalyst) sensor on its listed applications. Confirm the position your car needs, since the same engine can use different sensors front and rear.
- Do I need to splice wires?
- No. It comes with the factory-style connector and correct wire length, so it plugs into the existing harness.
- Will it clear my check-engine light?
- It clears oxygen-sensor codes caused by a failed sensor. If the fault is a wiring short, exhaust leak or bad catalytic converter, the light will return.
- What is in the box?
- One sensor with its connector and wiring. A sensor socket is not included, so you may need to borrow or buy one.

- Denso is a Toyota original-equipment supplier, and this sensor is built to that spec. Buy from a seller that lists the Denso part number 234-4018.
