MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-371

DIAGNOSIS

STEP 1. Check harness connector B-06 at the knock
sensor and harness connector B-10 at ECM for damage.
Q: Is the harness connector in good condition?

YES : Go to Step 2.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 3.

STEP 2. Check for short circuit to power supply between
knock sensor connector B-06 (terminal No. 2) and ECM
connector B-10 (terminal No. 25).
NOTE: Check harness after checking intermediate connector
B-24. If intermediate connector is damaged, repair or replace it.
Refer to GROUP 00E, Harness Connector Inspection

P.00E-2

.

Then go to Step 5.
Q: Is the harness wire in good condition?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Code Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

− ID

Codes Registration Judgment Table <Vehicles with
WCM>

P.42C-10

. Then go to Step 3.

NO : Repair it. Then go to Step 3.

STEP 3. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to

Diagnostic Function

− OBD-II Drive Cycle − Pattern 23

P.13A-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0328 set?

YES : Retry the troubleshooting.
NO : The inspection is complete.

DTC P0335: Crankshaft Position Sensor Circuit

.

CIRCUIT OPERATION

• The crankshaft position sensor power is supplied

from the ECM (terminal No. 9).

• Terminal No. 2 of the crankshaft position sensor

is grounded with ECM (terminal No. 24).

• A 5-volt voltage is applied on the crankshaft posi-

tion sensor output terminal (terminal No. 3) from
the ECM (terminal No. 8). The crankshaft position
sensor generates a pulse signal when the output
terminal is opened and grounded.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-373

TECHNICAL DESCRIPTION

• The crankshaft position sensor detects the crank

angle (position) of each cylinder, and converts
that data to pulse signals, then which are input to
the ECM.

• When the engine is running, the crankshaft posi-

tion sensor outputs a pulse signal.

• The ECM checks whether pulse signal is input

while the engine is cranking.

.

DESCRIPTIONS OF MONITOR METHODS

• Crankshaft position sensor signal does not

change.

• Crankshaft position sensor signal is not normal

pattern.

.

MONITOR EXECUTION

Continuous
