STEP 7. Replace the accelerator pedal position sensor.
(1) Replace the accelerator pedal position sensor.
(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 P2128 set?
YES : Replace the ECM. When the ECM is replaced,
register the ID code. Refer to GROUP 42B, ID Code
Registration Necessity Judgment Table <Vehicles
with KOS>
or GROUP 42C, ID Codes
Registration Judgment Table <Vehicles with WCM>
. Then go to Step 8.
NO : The inspection is complete.
STEP 8. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
(1) Turn the ignition switch to the "ON" position.
(2) After the DTC has been deleted, read the DTC again.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2128 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

.
THROTTLE POSITION SENSOR (main
and sub) RANGE/PERFORMANCE
PROBLEM CIRCUIT
• Refer to DTC P0122 − Throttle Position Sensor
(main) Circuit Low Input
• Refer to DTC P0222 − Throttle Position Sensor
(sub) Circuit Low Input
.
CIRCUIT OPERATION
• Refer to DTC P0122 − Throttle Position Sensor
(main) Circuit Low Input
• Refer to DTC P0222 − Throttle Position Sensor
(sub) Circuit Low Input
.
TECHNICAL DESCRIPTION
• ECM checks the throttle position sensor output
signal characteristics for abnormal conditions.
.
DESCRIPTIONS OF MONITOR METHODS
Detect malfunction if the relation between throttle
position sensor (main) and throttle position sen-
sor (sub) is wrong.

Judgement Criterion
• The difference between V1 and V2 is more than
0.3 volt for 0.3 second.
V1: Throttle position sensor (main) output voltage
V2: Throttle position sensor (sub) output voltage
subtracted from 5 volts
.

Check Conditions
• Throttle position sensor (main) output voltage is
between 0.2 and 4.8 volts.
• Throttle position sensor (sub) output voltage is
between 0.2 and 4.8 volts.
Judgement Criterion
• For 0.3 second, the sum of the output voltage of
the throttle position sensors (main) and (sub) is
4.5 V or less, or 5.5 V or more.

TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)
• Throttle position sensor failed.
• Harness damage in throttle position sensor circuit
or connector damage.
• ECM failed.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan tool (M.U.T.-III Sub Assembly)
• MB991824: V.C.I.
• MB991827: USB Cable
• MB991910: Main Harness A
STEP 1. Check harness connector B-11 at throttle position
sensor for damage.
Q: Is the harness connector in good condition?
YES : Go to Step 2.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 11.
STEP 2. Check the continuity at throttle position sensor
harness side connector B-11.
(1) Disconnect the connector B-11 and measure at the harness
side.
(2) Measure the continuity between terminal No. 3 and ground.
• Continuity (2 ohms or less)
Q: Does continuity exist?
YES : Go to Step 6.
NO : Go to Step 3.
STEP 3. Check harness connector B-09 at ECM for
damage.
Q: Q: Is the harness connector in good condition?
YES : Go to Step 4.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 11.
STEP 4. Check for harness damage between throttle
position sensor connector B-11 (terminal No. 3) and ECM
connector B-09 (terminal No. 13).
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair it. Then go to Step 11.
