MONITOR DESCRIPTION
If the ECM does not receive any IGF signals despite transmitting the IGT signal, it interprets this as a fault
in the igniter and sets a DTC.
If the malfunction is not repaired successfully, a DTC is set 1 second after the engine is next started.

2. P0456: EVAP very small leak
In operation C, the vacuum pump creates negative pressure (vacuum) in the EVAP system and the
EVAP system pressure is measured. If the stabilized system pressure is higher than second 0.02 inch
leak pressure standard, the ECM determines that the EVAP system has a small leak, illuminates the
MIL and sets the DTC (2 trip detection logic).

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle was running or stopped, whether the engine was
warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of
a malfunction.

DESCRIPTION
The stop light switch is a duplex system that transmits two signals: STP and ST1-. These two signals are
used by the ECM to monitor whether or not the brake system is working properly. If the signals, which
indicate the brake pedal is being depressed or released, are detected simultaneously, the ECM interprets
this as a malfunction in the stop light switch and sets the DTC.
HINT:
The normal conditions are as shown in the table below. The signals can be read using the intelligent
tester.
MONITOR DESCRIPTION
This DTC indicates that the stop light switch remains on. When the stop light switch remains ON during
"stop and go" driving, the ECM interprets this as a fault in the stop light switch and the MIL comes on and
the ECM stores the DTC. The vehicle must stop (less than 2 mph (3 km/h)) and go (19 mph (30 km/h) or
more) 5 times for two driving cycles in order to detect a malfunction.

DESCRIPTION
This monitor will run when the engine is started at -10 to 50C (14 to 122F) of the engine coolant
temperature. The DTC will set after the engine idling for 13 seconds (2 trip detection logic).
The DTC is designed to monitor the idle air control at cold start. When the engine is started at lower than
50
C (122F) of the engine coolant temperature, the ECM measures the accumulated mass air flow at the
engine idling. If it does not reach the criteria within 10 seconds, the ECM interprets this as a malfunction.
The MIL is illuminated and a DTC is set when the malfunction is detected in consecutive driving cycles (2
trip detection logic).
The ETCS (Electrical Throttle Control System) controls the idle speed. The ETCS operates the throttle
actuator to open and close the throttle valve, and adjusts the intake air amount to achieve the target idle
speed.
NOTICE:
When the negative battery terminal is disconnected during inspection or repairs, the ISC (Idle
Speed Control) learned values are cleared. ISC learning is performed when the engine has been
warmed up and idled for 5 minutes because this DTC cannot be set after the ISC learned values
cleared.
