Details On DTCs

DESCRIPTION

Engine oil level signal: engine oil level low

DETECTION CONDITION
Determination conditions
•  The oil level has decreased below L mark. (5 mm {0.197 in}below L mark on dipstick)
Preconditions
•  Engine speed: 750—3,000 rpm
•  Vehicle speed: 5 km/h {4 mph} or more
•  Engine oil control: during low oil pressure
•  Engine oil temperature: 20—120 °C {68—248 °F}
•  The following DTC is not detected:
―  Communication error between engine oil level sensor and PCM: U1100:00
―  Engine oil temperature sensor: P0196:00, P0197:00, P0198:00
―  Engine oil level sensor power supply circuit: P250C:00
Drive cycle
•  1
Self test type
•  CMDTC self test
Sensor used
•  PCM
•  Engine oil level sensor
•  Engine oil temperature sensor
•  Low-G (XY) sensor
FAIL-SAFE FUNCTION
•  Not applicable
VEHICLE STATUS WHEN DTCs ARE OUTPUT
•  Illuminates the wrench indicator light.
POSSIBLE CAUSE
•  Improper engine oil level (low)
•  Engine oil leakage
•  Engine oil level sensor malfunction
―  Clogging of oil passage to engine oil level sensor detection area
―  Engine oil level sensor internal application specific integrated circuit malfunction
•  Erratic signal to PCM
―  Engine oil level sensor connector or terminals malfunction
―  Open or short circuit in wiring harness between engine oil level sensor terminal C and PCM terminal 1Q
•  PCM malfunction


System Wiring Diagram

•  Not applicable

Function Explanation (DTC Detection Outline)

•  The PCM monitors the oil level while the preconditions are being met and if the traveled distance is 100 km {62.2 mile} or more or the monitoring time is 300 s or more, it calculates the average oil level.
•  If the averaged oil level decreases below L mark −5 mm {0.197 in}two times in a row, the PCM stores a DTC and flashes the wrench indicator light in the instrument cluster.
•  If the ignition is switched off after the wrench indicator begins illumination, it stops the wrench indicator light from illumination.
•  After verifying an oil level deficiency, the PCM re-implements the *1 determination if the ignition is switched ON and if a malfunction is determined, it turns on the wrench indicator light in the instrument cluster.

Repeatability Verification Procedure

1.  Move the vehicle to a level area and switch the ignition ON.
2.  Verify engine oil level using the dipstick (verify that it is near L— L−5 mm {0.197 in}).

STEP

INSPECTION

ACTION

1
PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the snapshot data on the repair order.
Go to the next step.
2
PURPOSE: VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
PURPOSE: IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA
•  Is the DTC P250F:00 on FREEZE FRAME DATA?
Yes
Go to the next step.
No
Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA.
4
PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY OTHER RELATED DTCs OCCURRING
•  Switch the ignition off, then ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Is the other PENDING CODE/DTC also present?
Yes
Go to the applicable DTC inspection.
No
Go to the next step.
5
PURPOSE: VERIFY IF THERE IS PID ITEM CAUSING DRASTIC CHANGES OF ACCELERATION FLUCTUATION BY INPUT SIGNAL TO PCM
•  Access the following PID using the M-MDS:
―  EOL
•  Is there any signal that is far out of specification?
Yes
Go to the next step.
No
Go to the troubleshooting procedure to perform the procedure from Step 1.
6
PURPOSE: VERIFY CONNECTOR CONNECTIONS
•  Access the following PID using the M-MDS:
―  EOL
•  When the following parts are shaken, does the PID value include a PID item which has changed?
―  Engine oil level sensor
―  PCM
Yes
Repair or replace the applicable connector parts.
Go to the troubleshooting procedure to perform the procedure from Step 4.
No
Go to the troubleshooting procedure to perform the procedure from Step 1.


Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
•  Step 1
―  Perform inspection of engine oil leakage.
•  Step 2
―  Perform inspection of engine oil level.
•  Step 3
―  Inspect for clogging of the oil passage to the engine oil level sensor detection area.
•  Step 4—5
―  Verify that the primary malfunction is resolved and there are no other malfunctions.

STEP

INSPECTION

ACTION

1
PURPOSE: INSPECT ENGINE OIL LEAKAGE
•  Start the engine.
•  Verify that there is no engine oil leakage in the hydraulic circuit.
•  Is there any leakage?
Yes
Repair or replace the malfunctioning part according to the inspection results, then add genuine motor oil.
Go to Step 4.
No
Replace the engine oil level sensor, then go to the next step.
2
PURPOSE: INSPECT ENGINE OIL LEVEL
•  Inspect the engine oil level.
•  Is the engine oil level sufficient?
Yes
Go to the next step.
No
Add genuine motor oil, then go to the next step.
3
PURPOSE: INSPECT FOR CLOGGING OF THE OIL PASSAGE TO THE ENGINE OIL LEVEL SENSOR DETECTION AREA
•  Remove the engine oil level sensor.
•  Visually inspect the oil passage to the engine oil level sensor.
•  Is there any restriction detected?
Yes
Clean the oil passage, then go to the next step.
No
Replace the engine oil level sensor, then go to the next step.
4
PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Implement the repeatability verification procedure.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
5
PURPOSE: VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
