Description
Product Overview
Ensure your fleet stays compliant with emissions regulations using the iFJF 5293295 NOx Nitrogen Oxide Sensor (5WK96692A). This precision-engineered sensor is designed specifically for Blue Bird school buses and commercial vehicles, providing accurate real-time nitrogen oxide readings to your vehicle's ECU for optimal emissions control and DPF regeneration management.
NOx sensors are critical components in modern diesel emission systems. A failing sensor can trigger check engine lights, reduce fuel economy, and potentially cause DPF-related issues that lead to costly downtime. This direct-fit replacement sensor restores proper emissions monitoring without the dealer price tag.

Why Replace Your NOx Sensor?
A malfunctioning NOx sensor can cause multiple issues: decreased fuel efficiency (up to 5-10%), failed emissions testing, reduced engine power (limp mode), and incomplete DPF regeneration leading to filter clogging. Replacing a faulty NOx sensor promptly saves on fuel costs and prevents more expensive downstream repairs.
Installation Tips
- Allow exhaust system to cool completely before removal
- Use anti-seize compound on threads (avoid getting on sensor tip)
- Torque to manufacturer specifications — do not overtighten
- Clear any existing DTC codes after installation
- Perform a short drive cycle to verify sensor readings
❓ Frequently Asked Questions
Q: Will this sensor fit my Blue Bird All American RE?
A: Yes. This NOx sensor is compatible with Blue Bird All American RE models from 2013 onward equipped with Cummins diesel engines. Always verify your existing part number matches 5293295 or 5WK96692A.
Q: Does this sensor require dealership programming?
A: In most cases, no. This is a smart sensor that self-calibrates. Some vehicles may require a DTC code clear using an OBD-II scanner after installation.
Q: How do I know if my NOx sensor is bad?
A: Common symptoms include Check Engine Light (P2200-P2299 codes), decreased fuel economy, failed emissions test, and black smoke from exhaust. A diagnostic scan tool can confirm NOx sensor failure codes.
Q: What's the difference between upstream and downstream NOx sensors?
A: Upstream sensors (before SCR/DPF) measure engine-out NOx. Downstream sensors (after SCR) verify catalyst efficiency. This sensor is typically an upstream unit — verify your application before ordering.
Q: How long does a NOx sensor typically last?
A: NOx sensors generally last 80,000-120,000 miles under normal conditions. Extreme exhaust temperatures, fuel quality issues, or excessive idling can shorten lifespan.
Q: Is this sensor compatible with Cummins ISB engines?
A: Yes. The Blue Bird school buses that use this sensor are typically equipped with Cummins ISB 6.7L diesel engines. Please confirm your existing sensor part number before purchase.
