2520490C1 | Genuine International® Diesel Exhaust Fluid Sensor And Pump Assembly

• Weight: 5 lbs
• Fit for: Navistar, International
  
• Functions:
  
  • Def injection: The pump delivers DEF to the exhaust stream, where it mixes with the exhaust gases and reacts with the NOx to form harmless nitrogen and water vapor.
    
  • Def level sensing: The DEF sensor continuously monitors the level of DEF fluid within the DEF tank. This information is used to determine when the DEF tank needs to be refilled.
    
  • Emissions control: By ensuring the proper delivery of DEF to the SCR system, the assembly helps to reduce NOx emissions, improving air quality and complying with emissions regulations.
    
  • Def pump control: The pump is responsible for delivering DEF to the SCR system. It is activated by the engine control module (ECM) based on the DEF level readings from the sensor and the engine's operating conditions.
    
  • Fault detection: The assembly can detect potential issues with the DEF system, such as low DEF levels, pump malfunctions, or sensor failures. It can trigger warning lights or limit engine power to prevent further damage.
