STEP 12. Check TP sensor connector B-07 and PCM
connector C-114 <2.4L Engine> or C-115 <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 13.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

STEP 13. Check the harness for a short circuit to ground
between TP sensor connector B-07 terminal 4 and PCM
connector C-54 <2.4L Engine> or C-55 <3.0L Engine>
terminal 46.
Q: Is the harness wire in good condition?

YES : Go to Step 5.

STEP 14. Check TP sensor connector B-07 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 15.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

STEP 15. Check the TP sensor.
(1) Disconnect connector B-07 and measure at the TP sensor

side.

(2) Measure the resistance between the TP sensor connector

terminals 1 and 4.

Standard value: 3.5

− 6.5 kΩ

(3) Measure the resistance between the TP sensor connector

terminals 1 and 3.

(4) Move the throttle valve from the idle position to full-open

position.

• The resistance should change smoothly in proportion to

the opening angle of the throttle valve.

Q: Does the resistance change smoothly between 3.5

− 6.5

Ω in proportion to the opening angle of the throttle

valve?
YES : Go to Step 16.
NO : Replace the TP sensor. Refer to GROUP 13A <2.4L

STEP 16. Check PCM connectors C-54 <2.4L Engine> or
C-55 <3.0L Engine> and 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 17.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

STEP 17. Check the harness for a short circuit to ground
or damage between TP sensor connector B-07 terminal 3
and PCM connector C-57 <2.4L Engine> or C-59 <3.0L
Engine> terminal 78.
Q: Is the harness wire in good condition?

YES : Go to Step 18.
NO : Repair or replace the harness wire.

STEP 18. Check the TP sensor connector and harness for
a short circuit to ground between the TP sensor and the
auto-cruise control-ECU connector.
Q: Are the connector and harness wire in good condition?

YES : Adjust the TP sensor. Refer to GROUP 13A <2.4L

Engine>, On-vehicle Service

− TP Sensor Adjustment

P.13A-927

or 13B <3.0L Engine>, On-vehicle Service

− TP Sensor Adjustment

DTC 14: TP Sensor System (Maladjusted Sensor)

TP Sensor System Circuit
Refer to

P.23A-43

CIRCUIT OPERATION
Refer to

P.23A-43

DTC SET CONDITIONS
If TP sensor output voltage is 0.2 volt or lower or if it
is 1.2 volts or higher when the engine is idling, the
TP sensor adjustment is judged to be incorrect and
DTC 14 is set.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)

• Malfunction of the TP sensor circuit

• Damaged harness, connector

• Malfunction of the PCM

DIAGNOSIS

Required Special Tool:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B

STEP 1. Using scan tool MB991958, read the A/T
diagnostic trouble code.

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) Check for A/T diagnostic trouble code.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the A/T DTC 11 or 12 set?

YES <DTC 11 set> : Refer to

P.23A-43

, DTC 11: TP Sensor

System (Short Circuit).

YES <DTC 12 set> : Refer to

P.23A-54

, DTC 12: TP

Sensor System (Open Circuit).

NO : Go to Step 2.
