Chrysler 6.7L 12V NOx Sensor 05149216AB 5WK96651A

Chrysler 6.7L 12V diesel engine NOx sensor, OEM 05149216AB and 5WK96651A interchangeable. Core function: monitor NOx concentration in exhaust and relay signal to ECU to adjust combustion and SCR system to maintain emissions compliance. Replacing resolves engine torque limitation, fault light, or excessive emissions, restoring power and fuel economy. If acceleration is weak, fuel consumption rises suddenly or the check engine light comes on, sensor aging is the likely cause; replace promptly.
