MULTIPORT FUEL INJECTION(MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L>

13A-22

NOTE: Do not replace the powertrain control module (PCM) until a through terminal check reveals there are
no short/open circuits.

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

NOTE: After the PCM 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 "*," the diagnostic trouble
code is recorded on the first detection of the malfunction.

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: Check that the powertrain control module (PCM) ground circuit is normal before checking for the
cause of the problem.

PROBLEM SYMPTOMS TABLE(FOR YOUR
INFORMATION)

ITEMS

SYMPTOM

Starting

Won't start

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

Fires up and dies The engine starts, but then the 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 usual 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 or while it is
being used.
