MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-54

NOTE: Do not replace the engine control module (ECM) until a through terminal check reveals there are no
short/open circuits.
NOTE: Check that the ECM ground circuit is normal before checking for the cause of the problem.
NOTE: After the ECM detects a malfunction, a diagnostic trouble code is recorded the next time the engine is
started and the same malfunction is re-detected. However, for items marked with a "*1", the diagnostic trou-
ble code is recorded on the first detection of the malfunction.
NOTE: The codes marked with a "*2" in the diagnosis code number column have the following two conditions
for recording the diagnostic trouble code.

• In case that the misfire causing the damaged catalyst is detected, the diagnostic trouble code is recorded

at the time.

• In case that the misfire deteriorating the exhaust gas is detected, the diagnostic trouble code is recorded

when the same malfunction is redetected after the next engine start.

NOTE: Sensor 1 indicates the sensor mounted at a position closest to the engine, and sensor 2 indicates the
sensor mounted at the position second closest to the engine.
NOTE: Bank 1 indicates the right bank side cylinder, and Bank 2 indicates the left bank side cylinder.

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

SYMPTOM CHART

M1131151502302

WARNING

When touching the throttle valve, surely shut off the
driving circuits of the throttle valve. In the event that
the throttle valve is operated, a finger might be
injured as the result of being caught by the throttle
valve.

CAUTION

During diagnosis, a DTC associated with other systems
may be set when the ignition switch is turned on with con-
nector(s) disconnected. On completion, confirm all sys-
tems for DTC(s). If DTC(s) are set, erase them all.

CAUTION

Disconnecting the battery cables or removing the combi-
nation meter will erase the learned value of the fuel gauge.
To recover the learned value, input a vehicle speed (by
actually driving the vehicle or inputting a simulated vehicle
speed), and stop the vehicle. This will complete the learn-
ing process.

NOTE: Check that the ECM ground circuit is normal
before checking for the cause of the problem.

ITEMS

SYMPTOM

At starting

Won't start

The starter cranks the engine, but there is no combustion within the
cylinders, and the engine won't start.

Starts up and
dies

The engine starts, but then engine soon stalls.

Hard starting

Engine starts after cranking a while.

Idling stability Hunting

Engine speed doesn't remain constant; changes at idle.

Rough idle

Usually, a judgement can be based upon the movement of the
tachometer pointer, and the vibration transmitted to the steering wheel,
shift lever, body, etc.

Incorrect idle
speed

The engine doesn't idle at the correct speed.

Engine stall (die
out)

The engine stalls when the foot is taken from the accelerator pedal,
regardless of whether the vehicle is moving or not.

Engine stall (pass
out)

The engine stalls when the accelerator pedal is depressed.
