Fuel Level Sensor Signal InspectionINFOID:0000000005395021
Symptom:• Improper fuel gauge indication.
• Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms do not indicate a malfunction.
• Depending on vehicle position or driving circumstance, the fuel level in the tank shifts and the indication may fluctuate.
• If the vehicle is fueled with the ignition switch ON, the indication will update slowly.
• If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction result-
ing in a change of reading.

A/T INDICATOR
A/T INDICATOR
System DescriptionINFOID:0000000005395032
The TCM receives A/T indicator signals from the transmission range switch (R-range, D-range, 2-range and 1-
range) and the combination meter (P-range and N-range). The TCM then sends A/T position indicator signals
to the combination meter via CAN communication lines. The combination meter indicates the received shift
position.

DIAGNOSIS AND REPAIR WORK FLOW
NO-1 >> No request for I/M examination from the custom
er: Before returning the vehicle to the customer,
always erase unnecessary DTC in ECM and TCM (Transmission Control Module). Refer to EC-
84, "Diagnosis Description".
NO-2 >> I/M examination, request ed from the customer: GO TO 13.
13.PREPARE FOR I/M EXAMINATION
1. Set SRT codes. Refer to EC-471, "
HowtoSetSRTCode".
2. Erase permanent DTCs. Refer to EC-473, "
How to Erase Permanent DTC".

Diagnostic Work SheetINFOID:0000000005398230
DESCRIPTION
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about an incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the one on the WORKSHEET
SAMPLE in order to organize all the information for troubleshooting.
Some conditions may cause the MIL to come on steady or blink and
DTC to be detected. Examples:
• Vehicle ran out of fuel, which caused the engine to misfire.
• Fuel filler cap was left off or incorrectly screwed on, allowing fuel to evaporate into the atmosphere.

INSPECTION AND ADJUSTMENT
• Each time electric throttle control actuator or ECM is replaced.
• Idle speed or ignition timing is out of specification.
IDLE AIR VOLUME LEARNING
: Special Repair RequirementINFOID:0000000005398245
1.PRECONDITIONING
Make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the follo wing 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: P or N (A/T), Neutral (M/T)
• Electric load switch: OFF (Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is
started the headlamp will not be illuminated.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- A/T models
• With CONSULT-III: Drive vehicle until “FLUID TEMP SE” in “DATA MONITOR” mode of “TRANSMISSION”
system indicates less than 0.9 V.
• Without CONSULT-III: Drive vehicle for 10 minutes.
- M/T models
• Drive vehicle for 10 minutes.
Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 3.
2.IDLE AIR VOLUME LEARNING
With CONSULT-III
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-25, "
ACCELERATOR PEDAL
RELEASED POSITION LEARNING : Special Repair Requirement".
2. Perform Throttle Valve Closed Position Learning. Refer to EC-25, "
THROTTLE VALVE CLOSED POSI-
TION LEARNING : Special Repair Requirement".
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode.
5. Touch “START” and wait 20 seconds.
Is
“CMPLT” displayed on CONSULT-III screen?
YES >> GO TO 4.
NO >> GO TO 5.
3.IDLE AIR VOLUME LEARNING
Without CONSULT-III
NOTE:
• It is better to count the ti me 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-25, "
ACCELERATOR PEDAL
RELEASED POSITION LEARNING : Special Repair Requirement".
2. Perform Throttle Valve Closed Position Learning. Refer to EC-25, "
THROTTLE VALVE CLOSED POSI-
TION LEARNING : Special Repair Requirement".
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 five times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
7. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops
blinking and turned ON.
8. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.
