BAROMETRIC PRESSURE SENSOR
A barometric pressure sensor is built into ECM. The barometric
pressure sensor is a semiconductor diffused pressure element
which outputs voltage to ECM according to atmospheric pres
-
sure. ECM uses this output voltage to sense the altitude of the
vehicle and compensates fuel injection volume to achieve the
appropriate air-fuel ratio for that altitude.
.
ENGINE OIL PRESSURE SWITCH
The engine oil pressure switch is installed on the left side of the
cylinder block. The engine oil pressure switch detects whether
the oil pressure is high or low using the contact switch. When
the oil pressure becomes higher than the specified value after
the engine starts, the contact point of the engine oil pressure
switch opens. This allows the ECM to detect the oil pressure is
higher than the specified value. The ECM outputs the OFF sig
-
nal to the combination meter through the CAN and then turns
off the oil pressure warning lamp.
