DIAGNOSIS AND TESTING
6. N0TE:Measure the oil pressure at an oil
temperature of 80°C.
N0TE:Oil pressure at 2000 rpm: 3.5 bar.
Measure the oil pressure.
7. Raise and support the vehicle. REFER to:
(I 00-02 Jacking and Lifting)
Jacking (Description and Operation), Lifting (Description and Operation).
8. Detach the oil pressure gauge and connector
from the oil pressure switch bore.
9. Coat the oil pressure switch with adhesive.
IQ Install the oil pressure switch. 11.
Connect the oil pressure switch electrical
connector to the oil pressure switch.
I2 Lower the vehicle.
Measure the oil pressure (Engine - 1.3L
Duratec-8V (Rocam))
N0TE:The oil pressure depends on various factors
(engine speed, oil temperature, oil viscosity, extent
of oil filter contamination).
N0TE:Measure the oil pressure at the specified
engine speed.
1. Raise and support the vehicle. REFER to:
( I (1 00-02 Jacking and Lifting)
Jacking (Description and Operation),
Lifting (Description and Operation).
2. Disconnect the oil pressure switch electrical
