Cardone NOx Sensor for Ram 3500
The Cardone 4N-3000 Nitrogen Oxide (NOx) Sensor monitors NOx output in diesel exhaust systems and reports elevated levels to the vehicle’s emissions controls. It is a direct-fit replacement for 2011-2012 Ram 3500 Downstream applications, helping restore proper emissions monitoring on Ram 3500 diesel models.
Key Features
- Direct plug-and-play fit for straightforward installation
- All components and hardware included to get the vehicle back to normal operating condition
- Rust-resistant construction for added service life
- Female connector with rectangular rounded-edge housing
- 4-blade male terminals with 14 AWG wiring and 23-inch harness length
- New sensor in metallic finish
Product Details
Built for diesel emissions control, the Cardone NOx Sensor line focuses on real-world performance and reliable signal reporting under everyday driving conditions. The 4N-3000 is engineered for downstream placement on 2011-2012 Ram 3500 trucks and is a direct replacement for Ram Trucks part number 5149216AB. This part cross-references Ram Trucks (e.g., 5149216AB) for the same application.
Compatible With 2011-2012 Ram 3500, downstream. Use this sensor when servicing the emissions system on Ram 3500 diesel trucks that require accurate NOx monitoring to maintain proper operation.
Common Issues This Sensor May Address
- Check engine light related to NOx sensor performance
- Incorrect NOx readings from the downstream exhaust sensor
- Emissions compliance faults on diesel vehicles
- Fault codes tied to exhaust aftertreatment monitoring
- Intermittent sensor signal or degraded sensor response
Installation Notes and Tips
Verify the connector shape, terminal count, and harness length before installation. This sensor uses a female connector, a plug-style terminal configuration, and a 23-inch harness, so matching the original routing and connector orientation is important. For best results, confirm the downstream location on the exhaust system before replacing the original unit.
Quality Assurance
Cardone NOx Sensors are tested for real-world use and built to provide dependable emissions monitoring in diesel applications. The product is new and intended to restore normal operating condition on the specified Ram 3500 fitment.
