Oxygen Sensors for Toyota Camry (2010-2011) 2.5L Upstream

Precision Upstream Air-Fuel Ratio Oxygen Sensor for 2010-2011 Toyota Camry (XV40)

What it Does: The Upstream Oxygen Sensor monitors exhaust gas oxygen content on the 2010-2011 Toyota Camry to restore real-time closed-loop ECU fuel trimming, stable idling, and optimal combustion efficiency.

The Stock Toyota Camry Sensor Degradation & Thermal Contamination

Over extended heat cycles, factory wideband air-fuel ratio sensors in the XV40 platform suffer from internal ceramic element poisoning, carbon loading, and reference air diffusion barrier degradation. As the OEM zirconia substrate degrades, response latency increases, skewing short-term and long-term fuel trims (STFT/LTFT). This latency forces the 2AR-FE powertrain control module into rich-running safeguard maps, triggering DTCs (such as P0138 or P2195), causing unburnt hydrocarbon build-up, catalyst overheating, rough idle harmonics, and severe degradation in fuel economy.

The Engineering Solution

This direct-replacement upstream air-fuel ratio sensor incorporates a planar zirconia sensing element housed in double-layered, high-grade stainless steel shielding to resist thermal shock, particulate fouling, and corrosive exhaust gas wash. Designed to directly supersede OEM numbers 89467-06100 and 89467-73010, it features an OE-spec 4-pin weather-pack connector for reliable signal telemetry and factory-calibrated internal ceramic heaters that achieve rapid closed-loop operational temperatures within seconds. Factory-coated M18 x 1.5 threads provide anti-seize performance for gall-free manifold installation.

Frequently Asked Questions & Fitment Warnings

Does this fit the XV40 Camry?

Yes, this is a direct fit for the 2010-2011 Toyota Camry equipped with the 2AR-FE 2.5L engine. Not compatible with 3.5L V6 (2GR-FE) models.

Do I need special tools to install this sensor?

Installation requires a standard 22mm (7/8-inch) slotted oxygen sensor socket to torque the M18 x 1.5 sensor body into the exhaust runner without pinching the factory wiring pigtail.
