Keep your engine's fuel management reading true with the DENSO Oxygen Sensor 234-4274. This 4-wire, heated, narrow-band sensor is a specific direct-fit unit that drops in across many Chrysler, Dodge, Jeep, Mitsubishi Raider, RAM, and Volkswagen Routan applications spanning engines such as the L4-2.4L, V6-2.7L, V6-3.5L, V6-3.8L, V6-4.0L, V8-4.7L, V8-5.7L, V8-6.1L and V8-6.4L — see the Buyer's Guide tab for the full 157-application list.

  • Laser-welded stainless housing: resists corrosion, while a PTFE filter blocks contaminants under harsh engine conditions.
  • Dual-layer protection: shields the ceramic element for fast, reliable response times.
  • Aluminum oxide trap layer: DENSO's design helps protect the ceramic element from silicone and lead poisoning.
  • Build spec: 4-wire, heated, narrow-band design with an 11.81-inch wiring harness.

An oxygen sensor measures the oxygen content in the exhaust and signals the ECU to trim the air-fuel ratio. A check engine light, poor fuel economy, or rough running can be signs an oxygen sensor may need replacing — diagnose the cause first, and if a failed sensor is confirmed, this replaces it. This sensor is cataloged for upstream and downstream positions (including left/right and front/rear variants) depending on the application; match the position listed for your vehicle. Country of origin: Japan.
