MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>
13A-505
STEP 9. Check for open circuit, short circuit to ground and
harness damage between throttle position sensor
connector B-06 (terminal No. 6) and PCM connector B-22
(terminal No. 98).
Q: Is the harness wire in good condition?
YES : Go to Step 10.
NO : Repair it. Then go to Step 11.
STEP 10. 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 P0222 set?
YES : Replace the PCM. Then go to Step 11.
NO : The inspection is complete.

STEP 11. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
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) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK"(OFF) position.
Q: Is DTC P0222 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

CIRCUIT OPERATION
• A 5-volt power supply is applied on the throttle
position sensor (sub) power terminal (terminal
No. 5) from the PCM (terminal No. 94).
The ground terminal (terminal No. 3) is grounded
with PCM (terminal No. 95).
.
TECHNICAL DESCRIPTION
• The throttle position sensor (sub) outputs voltage
which corresponds to the throttle valve opening
angle.
• The PCM checks whether the voltage is within a
specified range.
.
DESCRIPTIONS OF MONITOR METHODS
Throttle position sensor (sub) output voltage is out of
specified range.
.
MONITOR EXECUTION
Continuous
.
MONITOR EXECUTION CONDITIONS (Other
monitor and Sensor)
Other Monitor (There is no temporary DTC stored
in memory for the item monitored below)
• Not applicable
