Keep closed-loop fuel control accurate with the DENSO Auto Parts Oxygen Sensor 234-4588. This 4-wire, heated, narrow-band sensor is a direct-fit, specific-application replacement for a long list of 2004-2012 Chrysler, Dodge, Jeep, Mitsubishi, Ram and Volkswagen models — including the 2005-2010 CHRYSLER 300 (V8-5.7L), 2004-2010 CHRYSLER PT CRUISER (L4-2.4L), 2005-2010 DODGE DAKOTA (V6-3.7L), 2004-2006 JEEP WRANGLER (L6-4.0L) and 2009-2010 VOLKSWAGEN ROUTAN. See the Buyer's Guide tab for the full list of engines and positions.
The sensor measures the oxygen content in the exhaust stream and sends a signal to the engine's computer so it can adjust the air-fuel ratio during closed-loop operation. As a heated unit, it reaches operating temperature quickly for faster, more consistent readings after start-up.
- Corrosion-resistant housing: a laser-welded stainless housing resists corrosion while a PTFE filter blocks contaminants under harsh engine conditions.
- Protected ceramic element: dual-layer protection shields the ceramic element for fast, reliable response.
- Aluminum oxide trap layer: DENSO's exclusive trap layer is designed to protect the ceramic element from silicone and lead poisoning.
- Specs: 4-wire, heated, narrow-band design with a female connector, threaded mounting, 0.708 in thread diameter, and an 18.7 in wiring harness.
Quantity varies by engine and application — some listed applications use one sensor, others use two; it is sold individually. Country of origin: Japan.

Frequently Asked Questions
What does this oxygen sensor do?
It measures the oxygen content in the exhaust and signals the engine computer to fine-tune the air-fuel ratio for closed-loop fuel control. As a heated sensor, it reaches operating temperature quickly.
How many sensors will my vehicle need?
Quantity varies by engine and application — some listed applications use one and others use two. It is sold individually, so check the Buyer's Guide tab for your vehicle's quantity.
Is this an upstream or a downstream sensor?
This part is cataloged for both upstream and downstream positions depending on the application, so confirm the correct position for your vehicle in the Buyer's Guide tab.
What are the key specifications?
It is a 4-wire, heated, narrow-band sensor with a female connector, threaded mounting, a 0.708 in thread diameter, and an 18.7 in wiring harness. Country of origin: Japan.
What are the signs this sensor may need replacing?
If a failing oxygen sensor is the cause, you may see a check engine light, rough running, or reduced fuel economy. Diagnose the cause first, since other issues can produce the same symptoms.
