Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
3. ENABLE CONDITIONS
4. GENERAL DRIVING CYCLE
Perform the diagnosis continuously under 3000 rpm engine RPM.
5. DIAGNOSTIC METHOD
Abnormality Judgment
Judge as NG when all the malfunction criteria below are completed more than 10 times in a row.
Time Needed for Diagnosis: 10 engine rotations
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment
Judge as OK and clear the NG when the malfunction criteria below are met.
6. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
7. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
8. FAIL SAFE

GENERAL DESCRIPTION
CW:DTC P0519 IDLE CONTROL SYSTEM MALFUNCTION (FAIL-SAFE)
1. OUTLINE OF DIAGNOSIS
Detect malfunctions in which the engine RPM continues to rise during idling.
2. ENABLE CONDITIONS
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously if the vehicle speed at less than 4 km/h (2.49 MPH).
4. DIAGNOSTIC METHOD
Judge as NG when the continuous time until completing the all malfunction criteria below becomes more than
the time needed for diagnosis (2 seconds).
Time Needed for Diagnosis: 2 seconds
Malfunction Indicator Light: Illuminates as soon as a malfunction occurs.
Normality Judgment
Judge as OK and clear NG when the continuous time until completing the malfunction criteria below be-
comes more than the time needed for diagnosis (5 seconds).
5. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
6. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
7. FAIL SAFE
Fuel cut: Cuts off fuel only #1 and #2 cylinders, or for all cylinders according to vehicle speed, engine RPM,
and throttle position.
8. ECM OPERATION AT DTC SETTING
Memorize the freeze frame data. (For test mode $02)
Secondary Parameters Enable Conditions

A: REMOVAL
NOTE:
Before removing the oil pan upper, remove the en-
gine from vehicle. MOVAL, Engine Assembly.> 62, REMOVAL, Cylinder Block.>
1) Set the vehicle on a lift.
2) Lift-up the vehicle.
3) Remove the under cover.
4) Drain the engine oil. PLACEMENT, Engine Oil.>
5) Insert the oil pan cutter blade between oil pan
upper and oil pan lower.
CAUTION:
Do not use a screwdriver or similar tool in place
of oil pan cutter.
6) Remove the oil pan lower.
7) Remove the oil strainer.
B: INSTALLATION
CAUTION:
Before installing the oil pan, wipe clean the
mating surface of oil pan lower and oil pan up-
per.
1) Install the oil strainer onto oil pan upper.
NOTE:
Replace the O-ring with a new one.
Tightening torque:
6.4 N·m (0.65 kgf-m, 4.7 ft-lb)
2) Apply liquid gasket to the mating surfaces, and
install the oil pan.
