5.CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's engine ECM in check (test) mode, 1 trip detection logic is possible instead of 2 trip
detection logic, and sensitivity to detect faults is increased. This makes it eas\
ier to detect intermittent prob-
lems.
(a)Clear the DTC. (See step 3.)
(b)Set the check (test) mode. (See step 3.)
(c)Perform a simulation test. (See page 01±32)
(d)Check the connector and terminal. (See page 01±32)
(e)Wiggle the harness and the connector. (See page 01±32)
6. DATA LIST
HINT:
Using the DATA LIST displayed by the hand±held tester, you can read the value of the switches, sensors,
actuators and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one
of the method to shorten diagnostic time.
NOTICE:
The values given below for ºNormal Conditionº are representative valu\
es. A vehicle may still be nor-
mal even if the measured values are a little different from those listed here. Do\
not decide whether
a part is faulty or not solely according to the ºNormal Conditionº\
here.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the Hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALLº.
(g) According to the display on tester, read the ºDATA LISTº.

DTCP2111THROTTLE ACTUATOR CONTROL SYSTEM
± STUCK OPEN
DTCP2112THROTTLE ACTUATOR CONTROL SYSTEM ± STUCK CLOSED
CIRCUIT DESCRIPTION
The throttle motor is operated by the ECM and it opens and closes the throttle valve using gears. The open-
ing angle of the throttle valve is detected by the throttle position sensor\
which is mounted on the throttle body.
And, it provides feedback to the ECM to control the throttle motor in order \
to make the throttle valve opening
angle properly in response to the driving condition. If this malfunction is d\
etected, the ECM shuts down the
power for the throttle motor, and the throttle valve is closed by the return spring. And the throttl\
e valve is
locked at a certain opening angle. Also, the whole electronically controlled t\
hrottle operation is cancelled until
the system returns to normal and the ignition switch is turned OFF.
HINT:
This electrical throttle system is no used throttle cable.

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 determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1 INSPECT THROTTLE BODY ASSY(VISUALLY CHECK THROTTLE VALVE)
(a) Check it a foreign object has been caught between the throttle valve and the \
housing.

(a)Connect the oscilloscope to the terminals RR+ ± RR± and RL+ ± RL± of the skid control ECU.
(b)Drive the vehicle at about 30 km/h (19 mph), and check the signal waveform.
HINT:

As the vehicle speed (wheel revolution speed) increases,
a cycle of the waveform becomes shorter and the fluctua-
tion in the output voltage becomes greater.

When noise is identified in the waveform on the oscillo-
scope, error signals are generated due to the speed sen-
sor rotor's scratches, looseness or foreign matter depos-
ited on it.
