O2 Oxygen Sensor Upstream Downstream for Volvo S60 V70 XC60 (2008-2015) 3.0L 3.2L

Direct-Fit Upstream & Downstream O2 Oxygen Sensor Kit for 2008-2015 Volvo S60,V70,XC60 (P3)

What it Does: This matched upstream and downstream oxygen sensor kit restores closed-loop fueling and catalyst efficiency monitoring on 2008-2015 Volvo P3 models equipped with the B6304T 3.0L or B6324S 3.2L inline-6 engine.

The Stock Volvo S60,V70,XC60 Sensor Failure

Factory oxygen sensors on the Volvo P3 chassis endure extreme thermal cycling directly off the exhaust manifold on B6304T 3.0L and B6324S 3.2L inline-6 engines. Over time, internal ceramic elements suffer thermal shock cracking, oil-ash contamination, and internal heater burnout. Once upstream feedback drifts lazy or downstream switching slows, the ECM loses stoichiometric 14.7:1 control, triggering P0135, P0141, or false P0420 faults.

Common Symptoms of a Failing OEM Oxygen Sensor

• Check Engine Light & DTCs: Stored P0135, P0141, or P0133 codes caused by open heater filaments or sluggish sensor response.
• Fuel Trim Drift: Erratic voltage forces open-loop fueling, producing rough cold starts, exhaust soot, and reduced MPG.
• Failed Emissions: Inaccurate post-catalyst readings trigger P0420 warnings and prevent OBD-II readiness monitors from setting.

The Direct-Fit Upstream & Downstream O2 Sensor Solution

Replacing both sensors as a matched set eliminates response lag between pre-cat AFR and post-cat monitoring on your P3 inline-6. Each sensor utilizes laser-welded 310S stainless steel protective shrouds, platinum-coated zirconia sensing elements, and calibrated internal heaters for rapid light-off. Factory-length shielded harnesses with weather-sealed OEM-style connectors and anti-seize coated M18x1.5 threads ensure plug-and-play installation without cutting or splicing.

What's Included

• 1 Upstream Oxygen Sensor (Pre-Catalytic Converter)

Frequently Asked Questions & Fitment Warnings

Does this fit the P3 S60,V70,XC60?

Yes. This is a direct fit for the 2008-2015 Volvo S60,V70,XC60 equipped with the B6304T 3.0L or B6324S 3.2L inline-6 engine for the model years listed above. Excludes 2.0L, 2.5L, and unlisted models; confirm engine and year before ordering.

Will this clear P0135, P0141, or P0420 codes?

Yes, when triggered by sensor failure. Fresh upstream and downstream sensors resolve P0135/P0141 heater faults and lazy-switching P0420 codes once cleared, provided the catalytic converter substrate is intact.

Are the connectors plug-and-play for installation?

Yes. Pre-terminated OEM-style connectors require zero wiring modifications; chase corroded bung threads and torque each sensor to 30-35 ft-lbs.

The Volvo Precision Standard

Engineered to meet strict European emissions tolerances, this matched sensor set restores factory ECM closed-loop calibration and reliable CEL-free operation. Consistent air-fuel feedback keeps your P3 inline-6 running cleanly across all operating temperatures.
