or

｠

Misfire has occurred in 15 or more of the last 1,000
revolutions (corresponding to 1.5 times the limit of
emission standard).

OBD-II DRIVE CYCLE PATTERN

Refer to Diagnostic Function - OBD-II Drive Cycle -

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

｠

Spark plug failed.

｠

Ignition system related part(s) failed.

｠

｠

ECM failed.

DIAGNOSIS

STEP 1. Check the No. 6 cylinder ignition coil spark.

(1)

Remove the No. 6 cylinder ignition coil.

AA00

ZK603365

Spark plug

(2)

Remove the No. 6 cylinder spark plug and connect to the No.
6 cylinder ignition coil.

(3)

Ground the spark plug side electrode securely.

｠

When the engine is cranked, the spark plug should spark.

Q:Did it spark?

YES:

Go to Step 3.

NO:

Go to Step 2.

STEP 2. Check the No. 6 cylinder spark plugs.
Refer to GROUP 16, Ignition System - On-vehicle Service -
Spark Plug Check And Cleaning P.16c-4.

Q:Is the spark plug normal?

YES:

Refer to, INSPECTION PROCEDURE 24 - Ignition Circuit

System P.13Ab-826.

NO:

Replace the No. 6 cylinder spark plug. Then go to

Step 5.

STEP 3. Check the compression.
Refer to GROUP 11A, On-vehicle Service - Compression
Pressure Check P.11A-17.

Q:Are there any abnormalities?

MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS>

DIAGNOSTIC TROUBLE CODE PROCEDURES

YES:

Replace it. Then go to Step 5.

NO:

Go to Step 4.

STEP 4. Check the trouble symptoms.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 15 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0306 set?

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 5.

NO:

It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

STEP 5. 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 15 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0306 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

CIRCUIT OPERATION

｠

The knock sensor (terminal No. 1) sends a signal
voltage to the ECM (terminal No. 25).

｠

The ground terminal (terminal No. 2) is grounded
with ECM (terminal No. 42)

TECHNICAL DESCRIPTION

｠

The knock sensor converts the vibration of the
cylinder block into a voltage and outputs it. If there
is a malfunction of the knock sensor, the voltage
output will not change.

｠

The ECM checks whether the voltage output
changes.

DTC SET CONDITIONS

Check Conditions

｠

2 seconds or more have passed since the engine
starting sequence was completed.

｠

Engine speed is higher than 3,000 r/min.

｠

Volumetric efficiency is 40 percent or higher.

Judgement Criterion

｠

Knock sensor 1 output voltage (knock sensor peak
voltage in each 1/3 turn of the crankshaft) has not
changed more than 0.06 volt in the last consecutive
200 periods.

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

｠

Knock sensor 1 failed.

｠

Harness damage.

｠

Connector damage.

｠

ECM failed.
