DTC P0555 BRAKE BOOSTER PRESSURE SENSOR
CIRCUIT
DTC P0557 BRAKE BOOSTER PRESSURE SENSOR CIRCUIT LOW INPUT
DTC P0558 BRAKE BOOSTER PRESSURE SENSOR CIRCUIT HIGH INPUT
CIRCUIT DESCRIPTION
The brake booster pressure sensor detects internal pressure of the brake booster as voltage. A structure
of the sensor and its connection to the ECM are the same as those of the intake air pressure sensor (refer
to DTC P0105 on page 05 −61).
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 pressure. 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.

INSPECTION PROCEDURE
HINT:
S If different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may have an open circuit.
S Read freeze frame data using the hand−held tester . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1 CHECK VACUUM HOSES(BRAKE BOOSTER PRESSURE SENSOR − BRAKE
BOOSTER, INTAKE MANIFOLD − BRAKE BOOSTER)
(a) Check that the vacuum hoses are connected correctly.
(b) Check that the vacuum hoses are not loose or disconnected.
(c) Check the vacuum hoses and tubes for clogs, cracks, holes, damage, or blockage.
NG REPAIR OR REPLACE VACUUM HOSES
OK
2 INSPECT ECM(VC VOLTAGE)
(a) Turn the ignition switch to ON.
(b) Measure the voltage between the specified terminals of the E13 ECM connector.
Standard:
Tester ConnectionSpecified Condition
VC (E13 −18) − E2 (E13 −28)4.5 to 5.5 V
NG REPLACE ECM (See page 10 − 65 of Pub. No.
RM 1018E AVENSIS)

3 INSPECT ECM(PB VOLTAGE)
(a) Measure the voltage between the specified terminals of the E13 ECM connector.

(a) Disconnect the E13 ECM connector.
(b) Disconnect the B2 brake booster pressure sensor con-
nector.
(c) Check the resistance between the wire harness side con-
nectors.
