DTC SET CONDITIONS <Range/Performance problem-relation between main and 
sub>

Logic Flow Chart

Check Conditions

• The target output voltage of the throttle position 

sensor is 0.9 volt or less.

• 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.

• Battery positive voltage is higher than 8.3 volts.

Judgement Criterion

• Voltage obtained with the formula given below is 

0.3 volt or higher for 0.3 second: [throttle position 
sensor (main) voltage 

− throttle position sensor 

(sub) voltage]
NOTE: The throttle position sensor voltage used 
for the judgement is converted into the throttle 
position sensor voltage for the internal process-
ing by the ECM.

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

• Throttle position sensor failed.

• Throttle position sensor circuit harness damage, 

or connector damage.

• ECM failed.

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-657

STEP 1. Check harness connector B-08 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 

P.00E-2

. Then go to Step 11.

STEP 2. Check the continuity at throttle position sensor 
harness side connector B-08.
(1) Disconnect the connector B-08 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-10 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 

P.00E-2

. Then go to Step 11.

STEP 4. Check for harness damage between throttle 
position sensor connector B-08 (terminal No. 3) and ECM 
connector B-10 (terminal No. 13).
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO :  Repair it. Then go to Step 11.

STEP 5. 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 accelerator pedal 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 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− ID 

Codes Registration Judgment Table <Vehicles with 
WCM> 

P.42C-10

. Then go to Step 11.

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

Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunctions 

P.00-15

.

STEP 6. Check harness connector B-10 at ECM for 
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 7.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 11.

STEP 7. Check for harness damage between throttle 
position sensor connector B-08 (terminal No. 5) and ECM 
connector B-10 (terminal No. 12).
Q: Is the harness wire in good condition?

YES : Go to Step 8.
NO :  Repair it. Then go to Step 11.

STEP 8. Check for harness damage between throttle 
position sensor connector B-08 (terminal No. 4) and ECM 
connector B-10 (terminal No. 10).
Q: Is the harness wire in good condition?

YES : Go to Step 9.
NO :  Repair it. Then go to Step 11.
