DTC P0219:00 [MZ-CD 1.6]

DTC P0219:00	Engine overspeed condition
DETECTION CONDITION	• The PCM monitors the engine speed. If the engine speed does not decrease at a proportion of the threshold after the engine speed exceeds 6,000 rpm, the PCM determines that there is an engine overspeed condition.
POSSIBLE CAUSE	• Engine oil deterioration (high amount of fuel mixed in with engine oil) • PCV valve malfunction • PCV related hose clogged • Engine internal malfunction ― Oil loss through piston ― Oil loss through valves

DTC P0219:00

Engine overspeed condition

DETECTION CONDITION

• The PCM monitors the engine speed. If the engine speed does not decrease at a proportion of the threshold after the engine speed exceeds 6,000 rpm, the PCM determines that there is an engine overspeed condition.

POSSIBLE CAUSE

• Engine oil deterioration (high amount of fuel mixed in with engine oil)

• PCV valve malfunction

• PCV related hose clogged

• Engine internal malfunction

― Oil loss through piston

― Oil loss through valves

STEP	INSPECTION	ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
No	Go to the next step.
3	VERIFY ENGINE OIL CONDITION • Verify the engine oil condition (amount, color, smell). (See ENGINE OIL LEVEL INSPECTION [MZ-CD 1.6].) • Is the engine oil condition normal?	Yes	Go to the next step.
No	Add the engine oil or replace the engine oil. (See ENGINE OIL REPLACEMENT [MZ-CD 1.6].)
4	INSPECT PCV VALVE • Inspect the PCV valve and its installation. (See POSITIVE CRANKCASE VENTILATION (PCV) VALVE INSPECTION [MZ-CD 1.6].) • Is there any malfunction?	Yes	Repair or replace malfunctioning part according to inspection result. Then go to the next step.
No	Inspect the engine to see if there is oil loss through pistons or valves, and repair or replace the malfunctioning part. Then go to the next step.
5	VERIFY THAT DTC P0219:00 TROUBLESHOOTING IS COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Run the vehicle under the FREEZE FRAME DATA stored condition. • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZ-CD 1.6].) Go to the next step.
No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE • Perform the after repair procedure. (See AFTER REPAIR PROCEDURE [MZ-CD 1.6].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZ-CD 1.6].)
No	DTC troubleshooting completed.

INSPECTION

ACTION

VERIFY FREEZE FRAME DATA HAS BEEN RECORDED

• Has the FREEZE FRAME DATA been recorded?

Yes

Go to the next step.

Record the FREEZE FRAME DATA on the repair order, then go to the next step.

VERIFY RELATED REPAIR INFORMATION AVAILABILITY

• Verify related service repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

• If the vehicle is not repaired, go to the next step.

Go to the next step.

VERIFY ENGINE OIL CONDITION

• Verify the engine oil condition (amount, color, smell).

(See ENGINE OIL LEVEL INSPECTION [MZ-CD 1.6].)

• Is the engine oil condition normal?

Yes

Go to the next step.

Add the engine oil or replace the engine oil.

(See ENGINE OIL REPLACEMENT [MZ-CD 1.6].)

INSPECT PCV VALVE

• Inspect the PCV valve and its installation.

(See POSITIVE CRANKCASE VENTILATION (PCV) VALVE INSPECTION [MZ-CD 1.6].)

• Is there any malfunction?

Yes

Repair or replace malfunctioning part according to inspection result.

Then go to the next step.

Inspect the engine to see if there is oil loss through pistons or valves, and repair or replace the malfunctioning part.

Then go to the next step.

VERIFY THAT DTC P0219:00 TROUBLESHOOTING IS COMPLETED

• Is the same DTC present?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the PCM.

(See PCM REMOVAL/INSTALLATION [MZ-CD 1.6].)

Go to the next step.

VERIFY AFTER REPAIR PROCEDURE

• Perform the after repair procedure.

(See AFTER REPAIR PROCEDURE [MZ-CD 1.6].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [MZ-CD 1.6].)
