DENSO Auto Parts 234-4739 oxygen sensor for the 2000-2005 Mitsubishi Eclipse V6 3.0L, the 2006-2012 Eclipse V6 3.8L and other vehicles reads the oxygen in the exhaust so the engine computer can adjust fuel. It is a heated, narrow-band, direct-fit unit.
- Laser-welded stainless housing resists corrosion
- PTFE filter blocks contaminants under harsh engine conditions
- Dual-layer protection shields the ceramic element for fast, reliable response times
- Aluminum oxide trap layer protects the ceramic element from silicone and lead poisoning
Quick facts
- Part: DENSO Auto Parts 234-4739 oxygen sensor
- Fits: the 2000-2005 Mitsubishi Eclipse V6 3.0L, the 2006-2012 Eclipse V6 3.8L and other vehicles
- Position: Upstream
- Condition: New
A worn oxygen sensor can come with a check engine light, a rough idle or poorer fuel economy, though other problems can produce them too. Before replacing it, look over the wire and connector for cracks, melted insulation or fraying with the engine off and cool; a shop can test the sensor itself. If a failed sensor is the cause, this one replaces it.
Fits
It also works as an oxygen sensor for the 2004-2008 Mitsubishi Endeavor V6 3.8L, which takes one, and for the 1999-2003 Mitsubishi Galant V6 3.0L and the 2004-2009 Galant V6 3.8L. The maker builds and tests it to OE standards for an exact fit. This listing is one sensor. If your car is not named here, find its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right O2 sensor for a 2000-2005 Mitsubishi Eclipse V6 3.0L or a 2006-2012 Eclipse V6 3.8L?
Yes. DENSO Auto Parts 234-4739 fits the 2000-2005 Mitsubishi Eclipse V6 3.0L and the 2006-2012 Eclipse V6 3.8L. For another car, look it up in the "Vehicles it fits" section.
Does this Mitsubishi Galant oxygen sensor fit the 1999-2003 Galant V6 3.0L and the 2004-2009 Galant V6 3.8L?
Yes. DENSO 234-4739 fits both the 1999-2003 Galant V6 3.0L and the 2004-2009 Galant V6 3.8L, and each takes one sensor.
Is this DENSO Auto Parts oxygen sensor heated, and how many wires does it have?
Yes. It is a heated narrow-band sensor with 4 wires and a 14.57 in wire length, a male connector and a threaded mount.
What signs can go with a worn 4-wire oxygen sensor?
A check engine light, rough idle or poorer fuel economy can go with a worn sensor, though other faults cause them too. A shop can read the stored codes.
What does the aluminum oxide trap layer in this oxygen sensor do?
It is designed to protect the ceramic element from silicone and lead poisoning. The housing is laser-welded stainless, and a PTFE filter blocks contaminants.
