PACCAR 1826511PEX EGR Differential Pressure Sensor

The PACCAR 1826511PEX is an EGR differential pressure sensor designed for PACCAR MX13 diesel engines. It measures the pressure difference across the exhaust gas recirculation cooler to ensure precise EGR flow control and emissions regulation. The sensor features an electric signal output for direct ECU integration. This component serves as a direct replacement for OEM part numbers 1826511 and 1826511PEX. It is engineered to withstand high-temperature exhaust environments and vibration levels typical in Class 8 heavy-duty truck applications. Interchange references include A2512 and 8265.11.
