KNOCK SENSOR
N7lAK13AA
The knock sensor threads into the side of the cylinder
Knock sensors contain a piezoelectric material
j block below the intake manifold. When the knock
which constantly detects engine knock vibration and
sensor detects a knock in one of the cylinders, it
sends an input voltage (signal) to the PCM while
sends an input signal to the PCM. In response,
the engine operates. As the intensity of the engine
the PCM retards ignition timing for all cylinders by
knock increases, the knock sensor output voltage
a scheduled amount.
also increases.
Knock
BRAKE SWITCH
When the brake switch is activated, the power-train
control module (PCM) receives an input indicating
that the brakes are being applied. After receiving
this input the PCM maintains idle speed to scheduled
N71AKl4AA
RPM through control of the idle air control motor.
The brake switch is mounted on the brake pedal
support bracket.
BATTERY VOLTAGE
The power-train control module (PCM) monitors the
battery voltage input to determine fuel injector pulse
width and generator field control. If battery voltage
N71AK15AA
is low the PCM will increase injector pulse width
(period of time that the injector is energized).
