Why Choose This Level Sensor
The DEF level sensor is a critical emissions system component in your International Navistar MaxxForce-powered truck — it continuously monitors the DEF tank and feeds accurate level data to the ECM to keep the SCR system operating within regulatory compliance on commercial routes. A failed or inaccurate level sensor triggers fault codes, activates dashboard warnings, and can result in engine derate or shutdown conditions that ground vehicles and disrupt fleet schedules across Class 6, 7, and 8 commercial operations. This replacement unit delivers:
- Accurate DEF level monitoring – Engineered to meet the signal output, connector, and dimensional specifications of International Navistar MaxxForce engine DEF system requirements across Class 6, 7, and 8 truck platforms

- Durable construction – Built to withstand continuous DEF exposure, thermal cycling, vibration, and the demanding duty requirements of Class 6, 7, and 8 commercial truck operation
- Cost-effective solution – Aftermarket quality at a fraction of dealer pricing
