O2 Oxygen Sensor Upstream Downstream for Nissan Pathfinder (2013-2014) 3.5L

Direct-Fit O2 Oxygen Sensor Kit for 2013-2014 Nissan Pathfinder (R52)

What it Does: This 4-piece oxygen sensor kit monitors exhaust gas oxygen across both banks of the 2013-2014 Nissan Pathfinder R52 VQ35DE 3.5L V6 to maintain closed-loop fuel trim accuracy.

The Stock Nissan Pathfinder Sensor Failure

On the R52 Pathfinder equipped with the VQ35DE 3.5L V6, factory upstream air/fuel and downstream zirconia sensors endure thermal cycling up to 1,500°F. Carbon fouling, silicone contamination, and heater circuit fatigue gradually cause sluggish voltage switching and open coils. Once response lags, the ECM defaults to rich open-loop fueling, triggering codes like P0130, P0150, and P0031 while risking catalytic overheating.

Common Symptoms of Failing OEM Oxygen Sensors

• Check Engine Light / DTCs: Triggered P0130, P0150, or P0420/P0430 codes from slow sensor switching.
• Heater Circuit Faults: Extended open-loop warm-up and P0031/P0051 codes from burned-out heating elements.
• Rich Fueling & Economy Loss: Excessive fuel consumption and failed emissions from skewed Bank 1 and Bank 2 feedback.

The Direct-Fit 4-Sensor Solution

Replacing all four sensors together restores balanced Bank 1 and Bank 2 feedback on the VQ35DE 3.5L V6. Built with stainless steel housings, PTFE-insulated leads, and precision ceramic elements, these sensors match OEM resistance and response curves. Factory-style plug-and-play connectors and anti-seize coated threads eliminate splicing while directly replacing OEM part numbers 234-4595, 234-4599, and 234-9135.

Frequently Asked Questions & Fitment Warnings

Does this fit the R52 Pathfinder?

Yes. Fits 2013-2014 Nissan Pathfinder models with the VQ35DE 3.5L V6. Excludes 2014 2.5L Hybrid models; confirm engine before ordering.

Will this clear P0130 or P0420/P0430 codes?

Yes, when caused by faulty sensors. New units resolve P0130, P0150, and P0031 faults, though P0420/P0430 requires inspecting catalyst health.

Are OEM plugs included for installation?

Yes, all four sensors feature plug-and-play connectors. Pre-treat rusted exhaust bungs with penetrating oil and torque with a 22mm O2 socket.

The Nissan Precision Standard

Matched sensor replacement keeps the R52 VQ35DE at factory stoichiometric precision for clean emissions compliance and CEL-free operation.
