  • 【Tailored 2-Pcs Engine Solution】Package includes 1x upstream air-fuel ratio sensor equivalent to Denso 234-9049 and 1x downstream oxygen sensor equivalent to Denso 234-4622. Replacing worn sensors may help restore accurate fuel-trim feedback and emissions-system monitoring when the existing sensors are faulty.
  • 【Exact Fit & Direct Plug-In】 Features factory-style 4-pin connectors built strictly to OEM dimensions. No cutting, splicing, or modification required. Pre-coated with high-temperature anti-seize lubricant on threads for a hassle-free, true plug-and-play installation.
  • 【Compatible Signal Performance】 The upstream sensor is designed to provide air-fuel ratio feedback to the ECU on compatible Toyota and Scion applications. Correct vehicle, engine, connector, and OE-number matching is required for proper signal communication.
  • 【Important Verification Note】 Engineered exclusively for 1.8L and 1.5L engines (such as the 2009-2010 Corolla and 2004-2009 Prius). Does NOT fit 2.4L Camry or RAV4 models.
Related Diagnostic Trouble Codes
A faulty oxygen sensor may contribute to the diagnostic trouble codes below. These codes can also be caused by wiring faults, exhaust leaks, fuel-system issues, or catalytic-converter problems. Proper diagnosis is recommended before replacing any sensor.
  • Upstream (Sensor 1) Errors: P0031, P0032, P0134, P0135, P2195, P2196
  • Downstream (Sensor 2) Errors: P0136, P0137, P0138, P0141
  • Fuel System Trims: P0171, P0172
Diagnostic Note: P0420 often indicates a catalytic-converter or exhaust-system problem. A slow or faulty downstream sensor can sometimes contribute to an inaccurate reading, but this code does not confirm that the oxygen sensor is faulty.
