DENSO Auto Parts 234-9002 air / fuel ratio sensor for the 2000-2002 Toyota Tacoma 4-cylinder 2.7L, the 2001-2004 Tacoma 4-cylinder 2.4L and other vehicles reads the air-fuel ratio in the exhaust and reports it to the engine computer. The computer uses that reading to adjust fuel delivery.
- Laser-welded stainless housing resists corrosion
- PTFE filter blocks contaminants under harsh engine conditions
- Dual-layer protection around the ceramic element supports fast, reliable response times
- Heated wide-band sensor with a 4-wire connection
Quick facts
- Part: DENSO Auto Parts 234-9002 air / fuel ratio sensor
- Fits: the 2000-2002 Toyota Tacoma 4-cylinder 2.7L, the 2001-2004 Tacoma 4-cylinder 2.4L and other vehicles
- Position: Upstream
- Condition: New
A check engine light, rough running or poorer fuel economy can mean an air / fuel ratio sensor is worn, though other faults can show up the same way. Before you replace it, rule out damaged wiring and an exhaust leak near the sensor, and have the stored codes read.
Fits
This sensor is a direct-fit replacement for the 2000-2002 Toyota Tacoma 4-cylinder 2.7L, the 2001-2004 Tacoma 4-cylinder 2.4L, the 1999-2000 Toyota 4Runner 4-cylinder 2.7L and the 1999-2002 4Runner V6 3.4L. This listing is one sensor; the 1999-2002 4Runner V6 3.4L takes two and each of the other engines takes one.
