HEATER GP-JACKET WATER 4302751 - Caterpillar

Which Generate This Code:The supply voltage for the pressure sensors of the engine is below normal level.System Response:Electronic System Response All pressure sensors of the engine are set to default values. All diagnostic codes for the pressure sensors of the engine are disabled while this diagnostic code is active.Service Tool Display or Lamps Caterpillar Electronic Technician (ET) will display the default status of the sensors. This default status is indicated in the following list:
Boost pressure 0 kPa (0 psi)
Engine Oil Pressure 600 kPa (87 psi)
Atmospheric Pressure 100 kPa (15 psi)
Injection Actuation Pressure 17.5 kPa (2.50 psi)
Driver Current for the Injection Actuation System 40%ET will display "DIAG" next to the status of the sensor in order to indicate that the sensor is operating at the value that is shown due to an active diagnostic code.Engine Response An active diagnostic code may not cause any noticeable effect on engine response. However, the active diagnostic code may cause the engine to have the following effects:
Run rough.
Low powerThese effects are dependent on the operating conditions that exist at the time when the code occurs.Test Step 1. Perform the following diagnostic procedure: 5 Volt Engine Pressure Sensor Supply Circuit - TestResults:
