EGR Valve Revision Paccar Daf CF XF

Error Codes:
P1482 - EGR valve module, internal error
P1496 - Active engine protection system

The EGR valve with original code 2162360 è a component intended for heavy diesel engines of the DAF group, particularly for the unitsà Paccar MX-13 Euro 6It is an electronic valve for regulating the flow of recirculated exhaust gases, installed on the EGR manifold for active control of nitrogen oxide (NOₓ) emissions. This component è designed to withstand the high temperatures and pressures typical of industrial engines.

Technical specifications

The EGR valve 2162360 has the following main characteristics:

• Type: EGR control valve with integrated electric actuator
• Materials: high thermal resistance metal body, treated steel internal parts
• Actuation: stepper motor with integrated position sensor
• Control system: electronic control managed by the engine ECU
• Compatible with anti-pollution regulations Euro 6
• Equivalent and alternative codes: 2256370, 2128861, 2162359, 2339622

This valve canò be supplied in new or refurbished version, depending on the maintenanceà or replacement needs.

DIPA canò intervene to also revise this component whichì is important for the proper functioning of the engine.

Functionalityà

The function of the EGR valve è is to reduce NOₓ emissions by reintroducing a portion of the exhaust gases into the intake circuit. This allows for:

• Lowering of combustion temperature
• Reduction of harmful emissions, particularly nitrogen oxides
• Greater efficiency in the thermodynamic management of the engine under partial load conditions
• Collaboration with the SCR (Selective Catalytic Reduction) system to comply with Euro 6 limits

The EGR valve works in synergy with pressure, temperature, and position sensors, and è is an integral part of the exhaust gas after-treatment system.

Brand and model on which the part è is mounted.

DAF

• CF

All involved vehicles are part of the heavy segment and are intended for national and international transport.

DIPA recommends to always check compatibilityà based on the specific engine code and chassis number.

Defects and causes

The main defects found on the EGR valve 2162360 include:

• Mechanical blockage of the valve due to the accumulation of soot and particulate
• Actuator motor failure or failure of the integrated position sensor
• Internal leaks or seepage between the sealing seats
• Interrupted communication with the control unit due to electrical circuit failure
• Thermal cracks or deformations of the valve body, caused by extreme thermal cycles

In the presence of these faults, it is possible toò verify a drop in power, increased consumption, engine warning lights activation, and activation of theà protection mode.

Final conclusions

The DAF EGR valve with OE code 2162360 è a fundamental component of the Euro 6 industrial vehicle emissions control system. Installed on Paccar MX-13 engines, it ensures the reduction of NOₓ emissions through the controlled recirculation of exhaust gases.

DIPA supports customers even in after-sales. Itò can intervene to overhaul these components and restore them to full functionality,àwith cost savings on replacement and a benefit for the’environment thanks to’circular economy.
