STEP 2. Using scan tool MB991958, check data list item 11:
TP Sensor.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for item 11:

TP Sensor.

• With the throttle valve in the idle position, voltage should

measure between 535 and 735 mV.

• With the throttle valve in the full-open position, voltage

should measure between 4,500 and 5,500 mV.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 535 and 735 mV at

idle, and between 4,500 and 5,500 mV in the full-open
position?
YES : It can be assumed that this malfunction is intermittent.

.

NO : Go to Step 3.

STEP 3. Measure the TP sensor output voltage at TP
sensor connector B-07 by backprobing.
(1) Do not disconnect connector B-07.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 3 and ground by

backprobing.

• With the throttle valve in the idle position, voltage should

measure between 0.535 and 0.735 volts.

• With the throttle valve in the full-open position, voltage

should measure between 4.5 and 5.5 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 0.535 and 0.735 volt at

idle, and between 4.5 and 5.5 volts in the full-open
position?
YES : Go to Step 4.
NO : Go to Step 9.

STEP 4. Check the TP sensor output voltage at PCM
connector C-57 <2.4L Engine> or C-59 <3.0L Engine> by
backprobing.
(1) Do not disconnect connector C-57 <2.4L Engine> or C-59

<3.0L Engine>.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 78 and ground by

backprobing.

• With the throttle valve in the idle position, voltage should

measure between 0.535 and 0.735 volts.

• With the throttle valve in the full-open position, voltage

should measure between 4.5 and 5.5 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 0.535 and 0.735 volt at

idle, and between 4.5 and 5.5 volts in the full-open
position?
YES : Go to Step 5.
NO : Go to Step 7.

STEP 5. Check TP sensor connector B-07 and PCM
connector C-57 <2.4L Engine> or C-59 <3.0L Engine> for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 6.
NO : Repair or replace the damaged components. Refer to

STEP 6. Using scan tool MB991958, check data list item 11:
TP Sensor.

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) Set scan tool MB991958 to data reading mode for item 11:

TP Sensor.

• With the throttle valve in the idle position, voltage should

measure between 535 and 735 mV.

• With the throttle valve in the full-open position, voltage
