SERIES 60 FAULTY OIL PRESSURE GAUGE SENSOR

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

  1. Install the Diagnostic Data Reader to the vehicles Display Data Line Adaptor, see Figure 24089 ; refer to OEM guidelines.
  2. Start and vary the engine speed between 1800 - 2100 r/min.
  3. Visually examine the DDR for oil pressure reading.
    1. If the DDR indicates oil pressure greater than or equal 241 kPa (35 lb/in.2 ) at 1800 r/min, shut down the engine and disconnect the DDR, check oil pressure gage sensor line for obstruction; refer to section .
    2. If the DDR indicates oil pressure less than 241 kPa (35 lb/in.2 ) at 1800 r/min, shut down the engine; refer to section .

Oil Pressure Gage Sensor Replacement

Perform the following steps to replace the oil pressure gage sensor: ‪

  1. Remove and replace the oil pressure gage sensor; refer to OEM guidelines.
  2. Verify replaced oil pressure gage sensor; refer to section .
Test the Engine with Replaced Oil Pressure Gage Sensor

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

  1. Install the Diagnostic Data Reader to the vehicles Display Data Line Adaptor, see Figure 24089 ; refer to OEM guidelines.
  2. Start and run engine speed at 1800 r/min.
  3. Visually examine the DDR for oil pressure reading.
    1. If the DDR indicates oil pressure greater than or equal 241 kPa (35 lb/in.2 ) at 1800 r/min, shut down the engine and disconnect the DDR. No further troubleshooting is required.
    2. If the DDR indicates oil pressure less than 241 kPa (35 lb/in.2 ) at 1800 r/min, shut down the engine and disconnect the DDR. Check oil pressure gage sensor line for obstruction; refer to section .
