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.
[a] 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 gage.
[b] If DDDL 7.0 indicates oil pressure less than 241 kPa (35 psi) at 1800 rpm, shut
