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
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 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:

 tIt 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 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.

Q:Is the measured voltage between 4.9 and 5.1 volts?

YES:

 Go to Step 5.

NO:

 Go to Step 4.

STEP 4. Check for open circuit and harness damage and
short circuit to ground between the throttle position sensor
connector B-08 and the ECM connector B-10.

(1)

Disconnect the throttle position sensor connector B-08 and
the ECM connector B-10.
