A-Premium O2 Oxygen Sensor Replacement for Chrysler Dodge Jeep — 2-Pack Heated 4-Wire

If your vehicle is showing check-engine codes related to oxygen sensors or fuel trim, this A-Premium O2 sensor is built to match original equipment form and function for a broad range of models. Manufactured as a heated (4-wire) threaded sensor with a female connector, it arrives in a boxed 2-piece set and fits specific model years across Chrysler, Dodge, Jeep, Ram and a few Mercedes-Benz and Volkswagen Routan variants where service replacement part numbers align.

Which vehicles will this oxygen sensor fit?

This sensor covers many late-model Chrysler-family vehicles and selected Mercedes-Benz and Volkswagen Routan applications when the reference numbers match. Always compare the reference numbers and connector style before purchasing to confirm fitment.

• Also compatible with Volkswagen Routan (2009–2010) and some Mercedes-Benz models when the listed reference numbers match

How does the heated 4-wire design benefit performance?

The integrated heater speeds the sensor’s transition to operating temperature so the engine control unit receives accurate oxygen readings sooner after startup. This aids more stable idle control and more consistent fuel trim during warm-up without waiting for exhaust heat alone.

• 4-wire layout: dedicated heater plus signal/ground lines for reliable operation
• Faster activation: shorter cold-start period for quicker closed-loop fuel control
• OEM-style threaded mounting ensures correct positioning in the exhaust stream

What should I check before installing this replacement sensor?

Confirm connector gender, wire count, and the listed reference numbers match your original sensor. Inspect socket access and thread pitch to ensure the threaded mounting matches the original location and that the wiring harness reaches comfortably without strain.

• Reference numbers to compare: 4727446AD, 250-24253, 25024253
• Connector: female — verify compatibility with vehicle harness
• Wire count: 4 wires (heated sensor) — match to original sensor wiring
