STEP 4. Check for short circuit to ground between throttle
actuator control motor connector B-08 (terminal No. 1) and
ECM connector B-10 (terminal No. 15).
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO : Repair it. Then go to Step 7.

STEP 5. Check for short circuit to ground between throttle
actuator control motor connector B-08 (terminal No. 2) and
ECM connector B-10 (terminal No. 16).
Q: Is the harness wire in good condition?

YES : Go to Step 6.
NO : Repair it. Then go to Step 7.

STEP 6. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2101 set?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Code Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

. Then go to Step 7.

NO : It can be assumed that this malfunction is intermittent.

Refer to GROUP 00, How to Use

DTC P2122: Accelerator Pedal Position Sensor (main) Circuit Low Input

.

CIRCUIT OPERATION

• A 5-volt power supply is applied on the accelera-

tor pedal position sensor (main) power terminal
(terminal No. 1) from the ECM (terminal No. 75).

• A voltage that is according to the accelerator

opening angle is sent to the ECM (terminal No.
74) from the accelerator pedal position sensor
(main) output terminal (terminal No. 3).

• The ground terminal (terminal No. 2) is grounded

with ECM (terminal No. 76).

TECHNICAL DESCRIPTION

• The accelerator pedal position sensor (main) out-

puts voltage which corresponds to the accelera-
tor pedal depression.

• The ECM checks whether the voltage is within a

specified range.

.

DESCRIPTIONS OF MONITOR METHODS

Accelerator pedal position sensor (main) output volt-

age is out of specified range.

.

MONITOR EXECUTION

Continuous

.

MONITOR EXECUTION CONDITIONS
(Other monitor and Sensor)

Other Monitor (There is no temporary DTC stored

in memory for the item monitored below)

• Not applicable

Sensor (The sensor below is determined to be

normal)

• Not applicable

.

DTC SET CONDITIONS

.

Check Condition

• Ignition switch is "ON" position.

Judgement Criterion

• Accelerator pedal position sensor (main) output

voltage is 0.2 volt or less for 0.3 second.

.

OBD-II DRIVE CYCLE PATTERN

None.

.

TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)

• Accelerator pedal position sensor failed.

• Open or shorted accelerator pedal position sen-

sor (main) circuit, harness damage, or connector
damage.

• ECM failed.
