MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>
13A-659
STEP 9. Check for harness damage between throttle
position sensor connector B-08 (terminal No. 6) and ECM
connector B-10 (terminal No. 11).
Q: Is the harness wire in good condition?
YES : Go to Step 10.
NO : Repair it. Then go to Step 11.
STEP 10. Replace the throttle body assembly.
(1) Replace the throttle body assembly.
(2) Turn the ignition switch to the "ON" position.
(3) Erase the DTC.
(4) Depress the throttle fully for a few seconds.
(5) Check the DTC.
(6) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2135 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
or GROUP 42C, Diagnosis
− ID
Codes Registration Judgment Table <Vehicles with
WCM>
NO : The inspection is complete.
STEP 11. 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) Erase the DTC.
(4) Depress the throttle fully for a few seconds.
(5) Check the DTC.
(6) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2135 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

DTC P2138: Accelerator Pedal Position Sensor (main and sub) Circuit Range/Performance Problem
.
ACCELERATOR PEDAL POSITION
SENSOR (main and sub)
RANGE/PERFORMANCE PROBLEM
CIRCUIT
• Refer to DTC P2122 − Accelerator Pedal Position
Sensor (main) Circuit Low Input
.
• Refer to DTC P2127 − Accelerator Pedal Position
Sensor (sub) Circuit Low Input
.
.
CIRCUIT OPERATION
• Refer to DTC P2122 − Accelerator Pedal Position
Sensor (main) Circuit Low Input
.
• Refer to DTC P2127 − Accelerator Pedal Position
Sensor (sub) Circuit Low Input
.
.
TECHNICAL DESCRIPTION
• ECM checks the accelerator pedal position sen-
sor output signal characteristics for abnormal
conditions.
.
DESCRIPTIONS OF MONITOR METHODS
Detect malfunction if the relation between accelera-
tor pedal position sensor (main) and accelerator
pedal position sensor (sub) is wrong.
.

Logic Flow Chart
.
Check Condition
• Change of accelerator pedal position sensor
(sub) output voltage per 25 milliseconds is lower
than 0.06 volt.
Judgement Criterion
• Voltage obtained with the formula given below is
0.4 volt or higher for 0.3 second: [accelerator
pedal position sensor (sub) voltage
− accelerator
pedal position sensor (main) voltage].
NOTE: The accelerator pedal position sensor
voltage used for the judgement is converted into
the accelerator pedal position sensor voltage for
the internal processing by the ECM.

Check Condition
• Change of accelerator pedal position sensor
(sub) output voltage per 25 milliseconds is lower
than 0.06 volt.
Judgement Criterion
• Voltage obtained with the formula given below is
0.4 volt or higher for 0.2 second: [accelerator

TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)
• Accelerator pedal position sensor failed.
• Accelerator pedal position sensor circuit harness
damage, or connector damage.
• ECM failed.
