SHOP MANUALS AFFECTED

OIL PRESSURE SWITCH

The oil pressure switch is located at the center of the right-hand side of the engine. If the oil pressure in the lubricating system drops below 28 kPa (4 psi) during normal operation, the oil pressure warning light will come on. The hexagonal portion of this switch is 26 mm (1.024 in:) wide across the flats.

REMOVAL AND INSTALLATION





Using the special tool (09260-32000), install the oil pressure switch after applying sealant to the threaded area.

Sealant: Threebond 1104 or equivalent

NOTE:
Do not over torque the oil pressure switch.

Tightening torque
Oil pressure switch: 8-12 N-m (80-120 kg. cm, 5.8-8.7 lb.ft.)

INSPECTION





1. Check continuity between the terminal and body with an ohmmeter. If there is no continuity, replace the oil pressure switch.





2. Check continuity between the terminal and the body when a fine wire is inserted into the oil pressure switch oil hole. If there is continuity when the wire is pushed in, replace the switch.

Oil pressure switch operation pressure:
20-39 kPa (0.2-0.4 kg/sq.cm, 2.9-5-7 psi) V6 Only
14.7-29.42 kPa (0.1 5-0.3kg/sq.cm, 2.1-4.3 psi) Except V6
