Replacement DA96090007 Heated Oxygen Sensor 4-Wire Upstream OEM Replacement

The Replacement DA96090007 is a direct-fit, OEM-replacement upstream heated oxygen sensor designed for precise air-fuel ratio monitoring. This 4-wire heated O2 sensor allows the engine control module (ECM) to continuously adjust the fuel mixture for optimal combustion efficiency, improved fuel economy, and reduced emissions.

As an upstream (pre-catalytic converter) sensor, it plays a critical role in closed-loop fuel management. The integrated heater circuit brings the sensor up to operating temperature quickly after cold starts, ensuring accurate readings and minimizing warm-up emissions.

Key Features:

• OEM Replacement – Direct fit replacement for original equipment; no modifications required
• 4-Wire Design – Two heater wires and two signal wires for reliable, fast-heating performance
• Upstream Position – Mounts before the catalytic converter for primary fuel trim control
• Heated Element – Reaches operating temperature quickly for accurate readings from cold start
• Wideband Compatibility – Engineered to meet OEM signal output specifications
• Durable Construction – Built to withstand high exhaust temperatures and harsh underhood conditions

This oxygen sensor is a reliable, cost-effective alternative to dealer-sourced parts, restoring proper engine management and helping resolve fault codes such as P0135, P0141, and related O2 sensor diagnostic trouble codes (DTCs).
