connector
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).
⦆
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 between 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 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 3.
STEP 3. Check for open circuit and harness damage
between the throttle position sensor connector B-08 and
ECM connector B-10.
(1)
Disconnect the throttle position sensor connector B-08 and
the ECM connector B-10.
