Cummins ISL CM850 (2003-06) Fault Code: 432 PID: SID 230 SPN: 558 FMI: 13 Accelerator Pedal or Lever Idle Validation Circuit - Out of Calibration. Voltage at idle validation on-idle and off-idle circuit does not match accelerator pedal position.
Cummins ISL CM850 (2003-06) Fault Code: 433 PID: 102 SPN: 102 FMI: 2 Intake manifold pressure sensor circuit - data incorrect. An error in the intake manifold pressure sensor signal was detected by the ECM.
Cummins ISL CM850 (2003-06) Fault Code: 434 PID: SID 251 SPN: 627 FMI: 2 Power Supply Lost With Ignition On - Data Erratic, Intermittent or Incorrect. Supply voltage to the ECM fell below 6.2 VDC momentarily, or the ECM was not allowed to power down correctly (retain battery voltage for 30 seconds after key OFF).
Cummins ISL CM850 (2003-06) Fault Code: 435 PID: 100 SPN: 100 FMI: 2 Oil Pressure Switch Sensor Circuit - Data Erratic, Intermittent or Incorrect. An error in the engine oil pressure switch signal was detected by the ECM.
Cummins ISL CM850 (2003-06) Fault Code: 436 PID: 105 SPN: 105 FMI: 2 Intake Manifold 1 Temperature - Data Erratic, Intermittent, or Incorrect. The intake manifold temperature sensor is reading an erratic value at initial key ON.
Cummins ISL CM850 (2003-06) Fault Code: 441 PID: SID 168 SPN: 168 FMI: 1 Battery 1 Voltage - Data Valid but Below Normal Operational Range - Moderately Severe Level. ECM supply voltage is below the minimum system voltage level.
Cummins ISL CM850 (2003-06) Fault Code: 442 PID: 168 SPN: 168 FMI: 0 Battery 1 Voltage - Data Valid but Above Normal Operational Range - Moderately Severe Level. ECM supply voltage is above the maximum system voltage level.
Cummins ISL CM850 (2003-06) Fault Code: 443 PID: SID 221 SPN: 1043 FMI: 4 Accelerator Pedal or Lever Position Sensor Supply Voltage Circuit - Voltage Below Normal or Shorted to Low Source. Low voltage detected at sensor supply circuit to the accelerator pedal or lever position sensor.
Cummins ISL CM850 (2003-06) Fault Code: 449 (Auto) PID: 94 SPN: 157 FMI: 0 Injector Metering Rail Number 1 Pressure - Data Valid But Above Normal Operating Range - Most Severe Level. The ECM has detected that fuel pressure in the rail fuel is higher than the commanded pressure.
Cummins ISL CM850 (2003-06) Fault Code: 449 (ISC - Auto) PID: 94 SPN: 157 FMI: 0 Injector Metering Rail Number 1 Pressure - Data Valid But Above Normal Operating Range - Most Severe Level. Fuel pressure signal indicates that fuel pressure has exceeded the maximum limit for the given engine rating.
