Component Description
Engine oil pressure switches that monitor oil pressure at high
engine speed (switch-2) and oil pressure at low engine speed
(switch-1) are located on oil passage.
For detection of oil pressure at low engine speed, engine oil pres-
sure switch-1 turns oil pressure warning lamp ON if oil pressure
drops too low under normal engine running speed (below specified
pressure of engine oil pressure switch-1 at low engine speed).
For detection of oil pressure at high engine speed, engine oil pres-
sure switch-2 sends an ON signal to the ECM if oil pressure drops
lower than specified value when engine is running at high speed or
under high loading. Then the ECM turns oil pressure warning lamp
ON.

SYSTEM DESCRIPTION
This system improves acceleration when the air conditioner is used.
When the accelerator pedal is fully depressed, the air conditioner is turned off for a few seconds. When engine
coolant temperature becomes excessively high, the air conditioner is turned off. This continues until the cool-
ant temperature returns to normal.
