DriveWire REPH960932 Upstream Air/Fuel Ratio Oxygen Sensor 4-Wire OEM Replacement

The DriveWire REPH960932 is a direct-fit, OEM-replacement upstream air/fuel ratio (A/F) oxygen sensor designed for compatible Honda Civic and Acura CSX applications. This 4-wire sensor monitors the oxygen content in the exhaust stream before the catalytic converter, providing real-time feedback to the engine control module (ECM) to maintain optimal air/fuel mixture and combustion efficiency.

Key Features:

• Direct OEM Replacement — engineered to match the fit, form, and function of the original factory sensor
• 4-Wire Design — includes heater circuit wiring for faster sensor warm-up and reliable closed-loop operation
• Upstream / Pre-Cat Position — installs in the exhaust manifold position ahead of the catalytic converter
• Air/Fuel Ratio Sensor — wideband A/F sensor technology for precise mixture monitoring across a broad lambda range
• Plug-and-Play Fitment — OEM-style connector for straightforward installation without modification
• Helps Restore Performance — a faulty upstream O2/A/F sensor can cause poor fuel economy, rough idle, and failed emissions tests; this replacement restores proper ECM feedback

The DriveWire REPH960932 is built to meet or exceed OEM specifications, making it a reliable choice for restoring proper engine management and emissions performance. Compatible with select Honda Civic (2009–2011) and Acura CSX (2006–2011) models.
