Categories . In the meantime, you may lose your EGR valve actuation as it will be disabled. Amazon.com: Cummins SENSOR,PRES EGR : Automotive In addition, 3 hall effect sensors measure the valve position as the motor rotates to change its position according to the ECU signal. The sensor is not directly mounted to the exhaust manifold, but is instead located at the rear of the engine on the right side of the frame rail. The bad news is coming. Mopar Genuine Exhaust Sensor 68002442AA. May 17, 2011. Its location is on the intake manifold on the drivers side of the valve cover behind the air horn. kmdiesel 4384138 Exhaust Gas Pressure Sensor DPF Sensor Differential Pressure Sensor 4307166 4MPP2-13 fits Cummins ISB 6.7L. The Boost Pressure sensor is responsible for measuring the pressure generated by the turbocharger, which helps to increase the engines power output by forcing more air into the combustion chamber. The Cummins equivalent to this code is 2274 and it is defined as Engine Exhaust Gas Recirculation 1- Differential Pressure- Exhaust Gas Recirculation Differential Pressure Sensor Circuit - Voltage below normal or shorted to a low source. *Please Verify Your OEM Number Before Purchase Select delivery location. Remember, when ordering parts, always use the engine serial number. cummins isx egr differential pressure sensor location Our pressure sensors provide a precise electrical voltage that are available to cover 0-0.1psi through 0-10,000psi gage, absolute and differential with linear or non-linear outputs. pressure, which triggers code 1866 EGR diff. paulsrockymount Well take a look and remove the review if it doesnt follow our guidelines. By knowing where to look, you can quickly check the sensors condition and troubleshoot any problems related to fuel rail pressure, ensuring that your engine continues to run smoothly and efficiently. While the second one is on the tailpipe after the selective catalytic reduction (SCR) system. This produced the typical E.G.R. This can lead to inaccurate readings or complete failure of the sensor. The sensor is connected to the engine control unit (ECU) by an electrical connector and connected to the DPF via two silicon hoses. It measures the exhaust back pressure and sends the data to ECU to start the regeneration process to clean the filter.
