ENGINE OIL PRESSURE TEST - CONTINUED
N OT E
Engine oil pressure varies with engine speed. As engine speed increases, engine oil pressure increases up to
minimum of 29 psi (200 kPa).
9.
Record engine oil pressure readings when engine is at
operating temperature of 212F (100C) from measur-
ing equipment. Minimum engine oil pressure at high
idle is 29 psi (200 kPa). Minimum engine oil pressure
at low idle is 14.5 psi (100 kPa).
10.
Install engine oil pressure sensor (WP 0066 00).
11.
Compare recorded engine oil pressures with oil pres-
sure indicator on instrument cluster.
427-B0647
N OT E
A defective engine oil pressure indicator or sensor will give false indication of low or high oil pressure.
a.
If oil pressure indicator in cluster contradicts readings recorded from MSD or measuring equipment, replace oil
pressure sensor (WP 0066 00). If problem still exists, replace instrument cluster as necessary (WP 0051 00).
b.
If engine oil pressure is too low, refer to Low Oil Pressure in this work package.
c.
If engine oil pressure is too high, refer to High Oil Pressure in this work package.
