O2 Oxygen Sensor Upstream Downstream for Chrysler 200 (2011-2017) 3.6L

Direct-Fit Upstream & Downstream Oxygen Sensor Kit for 2011-2017 Chrysler 200 (JS / UF)

What it Does: This 4-piece O2 sensor kit monitors pre- and post-catalyst exhaust oxygen on the 2011-2017 Chrysler 200 (JS / UF, ERB 3.6L Pentastar V6) to regulate fuel trims.

The Stock Chrysler 200 Sensor Degradation

Factory oxygen sensors on the JS / UF platform with the ERB 3.6L Pentastar V6 endure extreme exhaust manifold heat soak and thermal cycling. Over time, carbon fouling, coolant or oil contamination, and internal heater circuit degradation degrade the zirconia sensing element. This slows closed-loop voltage switching across Bank 1 and Bank 2, triggering P0133, P0153, or P0420 fault codes while forcing the PCM into rich fuel trim compensation.

Common Symptoms of a Failing OEM Oxygen Sensor

• Check Engine Light / DTCs: Triggers P0133, P0153, or P0030 when heater circuits open or sensor response lags.
• Fuel Trim Drift: Sluggish voltage switching causes rich/lean oscillations, rough idle, and throttle hesitation.
• Emissions & Economy Loss: Skewed stoichiometry increases tailpipe emissions and lowers fuel efficiency.

The Direct-Fit Zirconia Sensor Solution

This matched 4-piece direct-fit oxygen sensor set replaces both upstream air-fuel ratio monitors and downstream catalyst efficiency sensors simultaneously. Built with high-temperature stainless steel housings, laser-welded protective shields, and fast-light-off internal heating elements, each sensor restores accurate millivolt feedback to the factory PCM. Pre-terminated OEM-style weatherpack connectors and anti-seize coated M18x1.5 threads ensure zero-splice, bolt-in installation on JS / UF exhaust manifolds and mid-pipes.

Frequently Asked Questions & Fitment Warnings

Does this fit the JS / UF 200?

Yes. Direct fit for 2011-2017 Chrysler 200 models equipped with the ERB 3.6L Pentastar V6. Excludes 2.4L 4-cylinder engines; confirm engine size before ordering.

Does this fix P0133 or P0420 codes?

Yes, when triggered by sensor failure. Matched replacement resolves slow-response P0133, P0153, and sensor-related P0420/P0430 faults.

Are harnesses plug-and-play?

Yes. Factory-style connectors install without splicing; torque to specification with a 22mm O2 sensor socket.

The Chrysler Precision Standard
