Section 2.4 Faulty Oil Pressure Gauge Sensor

Section 2.4
Faulty Oil Pressure Gauge Sensor

To determine if a faulty oil pressure gage sensor is causing low oil pressure, perform the following steps:‪

  1. Connect to DDDL 7.0.
  2. Start and vary the engine speed between 1800 - 2100 rpm.
  3. Visually examine DDDL 7.0 for oil pressure reading.
    1. If DDDL 7.0 indicates oil pressure greater than or equal 241 kPa (35 psi) at 1800 rpm, shut down the engine and disconnect DDDL 7.0, refer to OEM for the correct operation of the oil gauge.
    2. If DDDL 7.0 indicates oil pressure less than 241 kPa (35 psi) at 1800 rpm, shut down the engine; remove and replace the oil pressure gage sensor; refer to OEM guidelines.
  4. Verify replaced oil pressure gage sensor; refer to "2.4.1 Test the Engine with Replaced Oil Pressure Gauge Sensor" .

Section 2.4.1
Test the Engine with Replaced Oil Pressure Gauge Sensor

Perform the following steps to determine if replaced oil pressure gauge sensor resolved low oil pressure: ‪

  1. Connect to DDDL 7.0.
  2. Start and run engine speed at 1800 rpm.
  3. Visually examine DDDL 7.0 for oil pressure reading.
    1. If DDDL 7.0 indicates oil pressure greater than or equal 241 kPa (35 psi) at 1800 rpm, shut down the engine and disconnect DDDL 7.0. No further troubleshooting is required.
    2. If DDDL 7.0 indicates oil pressure less than 241 kPa (35 psi) at 1800 rpm, shut down the engine and disconnect DDDL 7.0. Refer to "2.5 Rocker Arm Shaft Plugs Missing (New or Rebuilt Engines Only)" .
