｠

Not continuity.

Q:Is the harness wire in good condition?

YES:

Go to Step 6.

NO:

Repair it. Then go to Step 8.

STEP 6. Using scan tool MB991958, check data list item 13:
Throttle Position Sensor (main).

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting 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
13, Throttle Position Sensor (main).

DIAGNOSTIC TROUBLE CODE PROCEDURES

｠

Output voltage should be between 0.3 and 0.7 volt when
the throttle valve is fully closed with your finger.

｠

Output voltage should be 4.0 volts or more when the
throttle 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 7.

STEP 7. Replace the throttle body assembly.

(1)

Replace the throttle body assembly.

(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 P0122 set?

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 8.

NO:

The inspection is complete.

STEP 8. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting 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)

After the DTC has been deleted, read the DTC again.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is DTC P0122 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

DIAGNOSTIC TROUBLE CODE PROCEDURES

CIRCUIT OPERATION

｠

A 5-volt power supply is applied on the throttle
position sensor (main) power terminal (terminal No.
5) from the ECM (terminal No. 12).
The ground terminal (terminal No. 3) is grounded
with ECM (terminal No. 13).

TECHNICAL DESCRIPTION

｠

The throttle position sensor (main) 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 (main) output voltage is out
of specified range.
