PACCAR PX-9 CM2350 (2013-17) Fault Code:2274 PID:411 SPN:411 FMI:4 Exhaust Gas Recirculation Differential Pressure Sensor Circuit – Voltage Below Normal or Shorted to Low Source
Geplaatst door Diezel Solutions op
Reason:Exhaust Gas Recirculation Valve Delta Pressure Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the EGR differential pressure sensor circuit. Effect:Possible reduced engine performance 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...
PACCAR PX-9 CM2350 (2013-17) Fault Code:2288 PID:103 SPN:103 FMI:0 Turbocharger 1 Speed – Data Valid But Above Normal Operating Range – Least Severe Level
Geplaatst door Diezel Solutions op
Reason:Turbocharger 1 Speed – Data Valid But Above Normal Operating Range – Least Severe Level. High turbocharger speed has been detected by the ECM. Effect:Possible reduced engine performance. Circuit Description:The 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 Location:The...

PACCAR PX-9 CM2350 (2013-17) Fault Code:2311 PID:SID 18 SPN:633 FMI:11 Electronic Fuel Injection Control Valve Circuit – Condition Exists
Geplaatst door Diezel Solutions op
Reason:Electronic Fuel Injection Control Valve Circuit – Condition Exists. The fuel pump actuator circuit resistance is too high or too low, or an intermittent connection has been detected. Effect:Possible reduced engine performance. Circuit Description:The 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 Location:The high-pressure fuel pump is mounted to the gear housing. The fuel pump...
