The park/neutral position switch goes on when the shift lever is in the N o\
r P shift position. If the shift lever
is moved from the N position to the D position, this signal is used for \
air±fuel ratio correction and for idle speed
control (estimated control), etc.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lean or rich, etc. at the time of the mal-
function.

When either one of the following conditions (a), (b), (c) or (d)\
is
satisfied (1 trip detection logic):
(a) If pressure inside the intake manifold is low, the brake
booster internal pressure is 38 kPa (285 mmHg, 11.2
in.Hg) or more higher than the intake manifold internal
pressure and this condition remains for more than 10
sec. (Pressure leaks caused by hose disconnection, etc).
(b) Pressure inside the brake booster stays low or at fixed lev- el, despite the vehicle has driven and stopped 10 times
(Vacuum stuck caused by hose clogged, etc).
(c) While the brake pedal is released, the pressure inside the brake booster is 32 kPa (240 mmHg, 9.4 in.Hg) or more
higher than the intake manifold internal pressure and this
condition remains for more than 1 sec. (Pressure leaks).
(d) After running the engine for more than 100 sec. with the brake pedal released and the negative pressure (vacuum)
has accumulated in the brake booster, the following two
conditions are satisfied despite depressing the brake
pedal for more than 1 sec. (Vacuum stuck):

Internal pressure of the brake booster does not increase

Internal pressure of the brake booster is 32 kPa (240 mmHg,
9.4 in.Hg) or more lower than the internal pressure of the
intake manifold

DTCP0555BRAKE BOOSTER PRESSURE SENSOR
CIRCUIT
DTCP0557BRAKE BOOSTER PRESSURE SENSOR CIRCUIT LOW INPUT
DTCP0558BRAKE BOOSTER PRESSURE SENSOR CIRCUIT HIGH INPUT
CIRCUIT DESCRIPTION
The brake booster pressure sensor detects internal pressure of the brake bo\
oster as voltage. A structure
of the sensor and its connection to the ECM are the same as ones for the i\
ntake air pressure sensor. (Refer
to DTC P0105 on page 05±342).
In order to purify emission gas when starting a cold engine, drastically\
retard the ignition timing to quickly
activate tha catalyst. Upon this, the throttle valve is opened larger than the throttle opening angle with\
a warm
engine, therefore the intake manifold pressure will be closer to atmospheric pr\
essure. If the negative pres-
sure (vacuum) applied inside the brake booster drops, the ECM cancels the drastic retarding timing and
introduces the negative pressure (vacuum) into the intake manifold, and the ECM \
then resumes the drastic
retarding timing after the brake booster negative pressure (vacuum) is ensured \
at required level.

DTC P0500 VEHICLE SPEED SENSOR ºAº
CIRCUIT DESCRIPTION
The speed sensor for skid control ECU detects the wheel speed and sends the appropriate signals to the
skid control ECU.
The skid control ECU converts these signals into a 4±pulse signal and outputs it to the combination meter.
After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit in-
side the combination meter,it is then transmitted to the ECM. The ECM determines the vehicle speed based
on the frequency of these pulse signals.
