Engine speed will not
rise more than 2,500 rpm
due to the fuel cut Malfunction indicator
lamp circuit When there is an open circuit on MIL circuit, the ECM cannot warn the
driver by illuminating MIL when there is malfunction on engine control
system.
Therefore, when electrical controlled throttle and part of ECM related
diagnoses are continuously detected as NG for 5 trips, ECM warns the
driver that engine control system malfunctions and MIL circuit is open
by means of operating the fail-safe function.
The fail-safe function also operates when above diagnoses except MIL
circuit are detected and demands the driver to repair the malfunction. EC-973

DTC Inspection Priority ChartINFOID:0000000009462544
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
P2100
P2103 Throttle control motor relay ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2101 Electric th rottle control
function ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2118 Throttle control motor ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring.
P2119 Electric thro ttle control ac-
tuator (When electric throttle control actuator does not function properly due to the return spring
malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the
idle position. The engine speed will not rise more than 2,000 rpm.
(When throttle valve opening angle in fail-safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to 20
degrees or less.
(When ECM detects the throttle valve is stuck open:)
While the vehicle is being driven, it slows down gradually because of fuel cut. After the
vehicle stops, the engine stalls.
The engine can restart in the N or P position, and engine speed will not exceed 1,000 rpm
or more.

IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000009462557
Idle Air Volume Learning is a function of ECM to learn
the idle air volume that keeps engine idle speed within
the specific range. It must be performed under the following conditions:
• Each time the electric throttle c ontrol actuator or ECM is replaced.
• Idle speed or ignition timing is out of the specification.
Work ProcedureINFOID:0000000009462558
1.PRECONDITIONING
Check that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.
• Battery voltage: More than 12.9 V (At idle)
• Engine coolant temperature: 70 - 100 °C (158 - 212 °F)
• Selector lever position: P or N
• Electric load switch: OFF
(Air conditioner, head lamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is
started the head lamp will not illuminate.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- With CONSULT: Drive vehicle until “ATF TEMP SEN” in “DATA MONITOR” mode of “CVT” system indicates
less than 0.9 V.
- Without CONSULT: Drive vehicle for 10 minutes.
Will CONSULT be used?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM IDLE AIR VOLUME LEARNING
With CONSULT
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-681, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-682, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEA RN” in “WORK SUPPORT” mode.
5. Touch “START” and wait 20 seconds.
Is
“CMPLT” displayed on CONSULT screen?
YES >> GO TO 4.
NO >> GO TO 5.
3.PERFORM IDLE AIR VOLUME LEARNING
Without CONSULT
NOTE:
• It is better to count the time accurately with a clock.
• It is impossible to switch the di agnostic mode when an accelerator pedal position sensor circuit has
a malfunction.
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-681, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-682, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Confirm that accelerator pedal is fully releas ed, turn ignition switch ON and wait 3 seconds.
6. Repeat the following procedure quickly 5 times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
7. Wait 7 seconds, fully depress the accelerator pedal for approx. 20 seconds until the MIL stops blinking
and turns ON.
8. Fully release the accelerator pedal within 3 seconds after the MIL turns ON.
