MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-335

DTC P0222: Throttle Position Sensor (sub) Circuit Low Input

.

CIRCUIT OPERATION

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

position sensor (sub) power terminal (terminal 
No. 5) from the ECM (terminal No. 12).

• A voltage that is according to the throttle opening 

angle is sent to the ECM (terminal No. 11) from 
the throttle position sensor (sub) output terminal 
(terminal No. 6).

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-336

• The ground terminal (terminal No. 3) is grounded 

with ECM (terminal No. 13).

.

TECHNICAL DESCRIPTION

• The throttle position sensor (sub) outputs voltage 

which corresponds to the throttle valve opening 
angle.

• The ECM checks whether the voltage is within a 

specified range.

.

DESCRIPTIONS OF MONITOR METHODS

Throttle position sensor (sub) output voltage is out of 

specified range.

.

MONITOR EXECUTION

Continuous

.

OBD-II DRIVE CYCLE PATTERN

None.

.

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

• Throttle position sensor failed.

• Open or shorted throttle position sensor (sub) cir-

cuit, harness damage, 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

• MB991658: Test Harness

STEP 1. Using scan tool MB991958, check data list item 15: 
Throttle Position Sensor (sub).

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) Detach the intake air hose at the throttle body.
(4) Disconnect the connector of the throttle position sensor.
(5) Use test harness special tool (MB991658) to connect only 

terminals No. 3, No. 4, No. 5, and No. 6.

(6) Set scan tool MB991958 to the data reading mode for item 

15, Throttle Position Sensor (sub).

• Output voltage should be 4.0 volts or more when the 

throttle valve is fully closed with your finger.

• Output voltage should be 1.0 volt or less when the throt-

tle valve is fully open with your finger.

(7) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : 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

.

NO :  Go to Step 2.

STEP 2. Check harness connector B-08 at throttle position 
sensor for damage.
Q: Is the harness connector in good condition?

YES : Go to Step 3.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 11.

STEP 3. Measure the sensor supply voltage at throttle 
position sensor harness side connector B-08.
(1) Disconnect the connector B-08 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 5 and ground.

• Voltage should be between 4.9 and 5.1 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.9 and 5.1 volts?

YES : Go to Step 7.
NO :  Go to Step 4.

STEP 4. Check harness connector B-10 at ECM for 
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 5.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 11.

STEP 5. Check for open circuit and short circuit to ground 
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 6.
NO :  Repair it. Then go to Step 11.
