Cummins X12 CM2350 X119B (2018 & Newer) Fault Code: 2272 PID: PID 27 SPN: 27 FMI: 4 EGR valve Position Circuit- Voltage Below Normal or Shorted to Low Source

Geplaatst door Diezel Solutions op

Circuit DescriptionThe exhaust gas recirculation (EGR) valve is controlled by a brushless motor located on top of the EGR valve. The EGR valve motor uses three different motor legs to move the valve through its range of motion. The ECM uses the EGR motor A, B, and C wires to command the EGR valve to the appropriate position in order to meet EGR flow targets.The EGR valve motor contains three position sensors that detect the location of the EGR valve. These sensors report the position of the valve back to the ECM over the EGR valve position A, B, and...

Cummins X12 CM2350 X119B (2018 & Newer) Fault Code: 2273 PID: PID 411 SPN: 411 FMI: 3 Exhaust Gas Recirculation valve Delta Pressure Sensor Circuit- Voltage Above Normal or Shorted to High Source

Geplaatst door Diezel Solutions op

Circuit DescriptionThe exhaust gas recirculation (EGR) differential pressure sensor has two ports that sense exhaust pressure. The sensor outputs a voltage which represents the pressure difference between the two ports located across an orifice in the EGR tube. The engine control module (ECM) uses this pressure to determine how much exhaust gas is flowing in the EGR connection tube to the intake manifold. This information is used to control the EGR valve for correct emission levels.The ECM provides a 5 volt supply to the EGR differential pressure sensor on the sensor supply circuit. The ECM also provides a ground on...

Circuit DescriptionThe turbocharger speed sensor is a variable reluctance speed sensor. It consists of a coil of wire and an iron core. The target on the turbocharger shaft is a ground flat in the center of the shaft. As the flat on the turbocharger shaft spins past the speed sensor, a signal is generated. The Engine Control Module (ECM) interprets this signal and converts it to a turbocharger speed reading. Component LocationThe turbocharger speed sensor is mounted in the center housing of the turbocharger. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running. Conditions for Setting...

Cummins X12 CM2350 X119B (2018 & Newer) Fault Code: 2311 PID: SID 018 SPN: 633 FMI: 31 Electronic Fuel Injection Control Valve Circuit- Condition Exists

Geplaatst door Diezel Solutions op

Circuit DescriptionThe circuit is a pulse-width modulation (PWM) driver in the engine control module (ECM) that controls the fuel pump actuator. The actuator is grounded in the ECM. The actuator is normally open. The PWM duty cycle to the fuel pump actuator depends on the difference between desired rail pressure and sensed rail pressure. Component LocationThe high-pressure fuel pump is mounted to the gear housing. The fuel pump actuator is mounted on the fuel pump. The fuel pressure sensor is mounted in the high pressure fuel rail. The fuel pressure relief valve is mounted on the high pressure fuel rail....
