MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-601

STEP 5. Check the MFI relay.
(1) Remove the MFI relay.
(2) Check for continuity between the MFI relay terminals No. 1

and No. 3.

• There should be continuity.

(3) Use jumper wires to connect MFI relay terminal No. 3 to the

positive battery terminal and terminal No. 1 to the negative
battery terminal.

(4) Check for continuity between the MFI relay terminals No. 4

and No. 2 while connecting and disconnecting the jumper
wire at the negative battery terminal.

• Continuity (2 ohms or less) <Negative battery terminal

connected>

• Should be open loop <Negative battery terminal discon-

nected>

(5) Install the MFI relay.
Q: Is the measured resistance within the specified range?

YES : Go to Step 6.
NO : Replace the MFI relay. Then go to Step 8.

STEP 6. Check for short circuit to ground between MFI
relay connector A-33X (terminal No. 1) and ECM connector
B-11 (terminal No. 73).
Q: Is the harness wire in good condition?

YES : Go to Step 7.
NO : Repair it. Then go to Step 8.

STEP 7. 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 P0606 set?

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

. Then go to Step 8.

NO : It can be assumed that this malfunction is intermittent.

STEP 8. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
(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 P0606 set?

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

DTC SET CONDITIONS

Check Condition

• Ignition switch is "ON" position.

Judgment Criterion

• When the input voltage from the accelerator

pedal position sensor (sub) is periodically 0 V for
0.45 second, the digital value of the input voltage
indicates 0.2 V or more.

OBD-II DRIVE CYCLE PATTERN

None.

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

• ECM failed.

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: USB Cable

• MB991910: Main Harness A

STEP 1. 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) Read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P060B set?

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

DTC SET CONDITIONS

Logic Flow Chart

Check Condition

• Change of accelerator pedal position sensor

(sub) output voltage per 40 milliseconds is lower
than 0.06 volt.

• Range/performance error of accelerator pedal

position sensor (main and sub) circuit is not
detected.

Judgment Criterion

• Voltage obtained with the formula given below is

0.4 volt or higher for 0.5 second: accelerator
pedal position sensor (main) output voltage

−

accelerator pedal position sensor (sub) output
voltage.

NOTE: The accelerator pedal position sensor
voltage used for the judgement is converted into
the accelerator pedal position sensor voltage for
the internal processing by the ECM.

OBD-II DRIVE CYCLE PATTERN

None.

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

• Accelerator pedal position sensor failed.

• ECM failed.
