DENSO Auto Parts Air / Fuel Ratio Sensor P/N:234-5014
DENSO Auto Parts 234-9001 air / fuel ratio sensor for the 2000-2004 Toyota Tacoma 4-cylinder 2.7L or V6 3.4L, 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.
A failing air / fuel ratio sensor can show up as a check engine light, poor fuel economy or a rough idle. A vacuum leak, an exhaust leak or a fouled spark plug can be behind those signs too, so find the cause before you buy a new sensor.
This is a direct-fit replacement for the 2000-2004 Toyota Tundra V6 3.4L and the 2000 Toyota 4Runner 4-cylinder 2.7L, along with the Tacoma engines named above. This listing is one sensor; the V6 3.4L engines take two of them and the 4-cylinder engines take one.
