Mopar Performance 56028996AA Oxygen Sensor Right Side After Catalyst

The Mopar Performance 56028996AA is a genuine OEM oxygen sensor designed for precise emissions monitoring and engine performance optimization. This downstream oxygen sensor is positioned after the catalytic converter on the right side of the exhaust system, where it continuously monitors oxygen levels in the exhaust gases and transmits critical data to the engine control unit.

Key Features:

• Genuine Mopar OEM part ensuring exact fit and reliable performance
• Post-catalyst placement for emissions control diagnostics and system monitoring
• Compatible with V6, 5.7L V8 HEMI, and 8.3L V10 SFI engines
• Provides accurate oxygen level feedback to optimize fuel injection and ignition timing
• Helps maintain proper air/fuel ratio for improved fuel economy and reduced emissions
• Manufactured to stringent factory specifications with rigorous testing
• Backed by Mopar's limited warranty for peace of mind

This oxygen sensor plays a vital role in your vehicle's powertrain control system by measuring post-catalyst exhaust oxygen levels. The sensor reacts with oxygen to produce a voltage output that varies based on oxygen content, allowing the PCM to make precise adjustments to fuel injector pulse width and maintain the ideal 14.7:1 air-to-fuel ratio for optimal emissions and fuel economy. Proper installation requires correct thread sealing, secure electrical connection, and torque to manufacturer specifications.
