O2 Oxygen Sensor Upstream Downstream for Dodge Caliber Avenger Journey (2011-2018) 2.0L 2.4L

Direct-Fit O2 Oxygen Sensor Kit for 2011-2018 Dodge Caliber, Avenger & Journey (PM/JS/JC)

What it Does: This matched upstream and downstream oxygen sensor kit monitors exhaust oxygen on 2011-2018 Dodge PM, JS, and JC models with ECN 2.0L or ED3 2.4L engines to regulate air-fuel stoichiometry.

The Stock Dodge Caliber, Avenger & Journey Sensor Failure

OEM sensors on PM, JS, and JC vehicles with ECN 2.0L and ED3 2.4L engines fail from severe thermal cycling, carbon soot buildup, and heater element burnout. When heat soak fractures the internal zirconia substrate, switching response degrades and triggers P0131, P0134, or P0420 fault codes. Compromised seals also allow moisture into the harness, corrupting PCM fuel-trim readings.

Common Symptoms of a Failing OEM Oxygen Sensor

• Check Engine Light / DTCs: Triggers P0131, P0134, or P0420 from slow switching or open heater circuits.
• Rough Idle: Skewed feedback forces rich open-loop fueling under load.
• Failed Emissions: Uncontrolled ratios spike hydrocarbon output and fuel consumption.

The Direct-Fit Dual-Sensor Solution

This matched pair replaces OEM 234-4547 for upstream and downstream positions on Federal-emissions configurations. Each unit utilizes a fast-acting zirconia ceramic element inside a laser-welded stainless shield to resist thermal shock and exhaust corrosion. Factory-length leads and keyed OEM connectors enable direct plug-and-play installation without cutting wires, restoring crisp voltage switching across ECN 2.0L and ED3 2.4L engines.

What's Included

• 1x Upstream Oxygen Sensor (234-4547)
• 1x Downstream Oxygen Sensor (234-4547)

Frequently Asked Questions & Fitment Warnings

Does this fit the PM, JS, and JC Caliber, Avenger, and Journey?

Yes. Fits listed 2011-2018 Dodge ECN 2.0L and ED3 2.4L models. Excludes 4-sensor California-emissions packages and V6 engines.

Will this clear P0131, P0134, or P0420 codes?

Yes, if sensor-related. Clears O2 switching and heater codes; damaged converters still trigger P0420.

Is wire splicing required for installation?

No. Pre-terminated OEM connectors install directly; apply thread anti-seize only and torque to spec.

The Dodge Precision Standard

Restoring closed-loop fueling keeps your ECN 2.0L or ED3 2.4L running efficiently without CEL faults. Replacing both sensors ensures balanced fuel trims.
