Diagnostic Trouble Code (DTC) Detecting Criteria

GENERAL DESCRIPTION

BZ:DTC P0351 IGNITION COIL A PRIMARY/SECONDARY CIRCUIT

1. OUTLINE OF DIAGNOSIS

Based on the self-diagnostic result of the ignition coil driving IC, judge the ignition coil driving circuit as normal

or abnormal.

The ignition coil driving IC detects “no ignition” status as a malfunction.

2. ENABLE CONDITIONS

3. GENERAL DRIVING CYCLE

Always perform the diagnosis continuously.

4. DIAGNOSTIC METHOD

• Abnormality Judgment
Judge as NG when the following conditions are established.

Time Needed for Diagnosis: 2500 ms

Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
• Normality Judgment
Judge as OK and clear the NG if the following conditions are established.

Time Needed for Diagnosis: Less than 1 second

Diagnostic Trouble Code (DTC) Detecting Criteria

GENERAL DESCRIPTION

CD:DTC P0365 CAMSHAFT POSITION SENSOR “B” CIRCUIT (BANK 1)

1. OUTLINE OF DIAGNOSIS

Detect the open or short circuit of the camshaft position sensor.

When there is no camshaft position signal input continuously, judge as NG.

2. ENABLE CONDITIONS

3. GENERAL DRIVING CYCLE

Always perform the diagnosis continuously.

4. DIAGNOSTIC METHOD

• Abnormality Judgment
Judge as NG when no input of camshaft position sensor signal in TDC remains for 10 time(s).

Time Needed for Diagnosis: TDC × 10 time(s)

Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
• Normality Judgment
Judge as OK and clear the NG when the malfunction criteria below are met.

Time Needed for Diagnosis: Two engine revs.

GENERAL DESCRIPTION

CE:DTC P0366 CAMSHAFT POSITION SENSOR B CIRCUIT RANGE/PERFOR-

MANCE (BANK 1)

1. OUTLINE OF DIAGNOSIS

Detect the malfunction of camshaft position sensor property.

Judge as NG when the number of camshaft signals remains abnormal.

2. ENABLE CONDITIONS

3. GENERAL DRIVING CYCLE

Always perform the diagnosis continuously.

4. DIAGNOSTIC METHOD

• Abnormality Judgment
Judge as NG when the status where the number of camshaft position sensor signal in two crankshaft revo-

lutions is other than 2 time(s).

Time Needed for Diagnosis: Two engine revs. × 4 time(s)

Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
• Normality Judgment
Judge as OK and clear the NG when the malfunction criteria below are met.
