STEP 6. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to

Diagnostic Function

− OBD-II Drive Cycle Pattern 17

P.13B-11

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0221 set?

YES : Retry the troubleshooting.
NO : The procedure is complete.

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-394

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).

• 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.

DTC SET CONDITIONS

Logic Flow Chart

Check Condition

• Ignition switch is "ON" position.

Judgement Criterion

• Throttle position sensor (sub) output voltage

should be 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:)

• Throttle position sensor failed.

• Connector damage

• Harness 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

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-396

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 the throttle
position sensor and harness connector B-10 at the ECM
for damage.
Q: Is the harness connector in good condition?

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

Inspection

P.00E-2

. Then go to Step 8.

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 5.
NO : Go to Step 4.
