Code No. P00CF: Abnormal Correlation Between Boost Pressure Sensor And Barometric Pressure Sensor
 
 
 
 
FUNCTION
  • The engine-ECU detects abnormality in the sensor by comparing the boost pressure sensor output with the barometric pressure sensor output.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • Engine is running.
  • Engine coolant temperature is more than 0°C.
  • More than 2 seconds have passed since the air flow sensor output is less than 6 g/sec.
Judgement Criterion
  • Difference between barometric pressure sensor output and boost pressure sensor output is more than 12 kPa for 2 seconds.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • None
 
 
PROBABLE CAUSES
  • Failed boost pressure sensor
  • Harness damage in boost pressure sensor circuit or loose connector contact
  • Failed barometric pressure sensor in the engine-ECU
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code
Is any other diagnosis code than P00CF set?
Inspection chart for diagnosis code (Refer to ).
Go to Step 2.
 
STEP 2. Check of damage in UPS5 line between boost pressure sensor connector and engine-ECU connector.
Is the check result normal?
Go to Step 3.
Repair the connector(s) or wiring harness.
 
STEP 3. Check of damage in UPS line between boost pressure sensor connector and engine-ECU connector.
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. Check of damage in E line between boost pressure sensor connector and engine-ECU connector.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. M.U.T.-IIISE data list
  • Data list reference table (Refer to ).
    1. Item 8: Manifold absolute pressure sensor
    2. Item BB: Barometric pressure sensor
    3. Item 125: Boost pressure sensor 1
Is the check result normal?
Go to Step 6.
Replace the sensor that has shown an abnormal data value.
 
STEP 6. M.U.T.-IIISE diagnosis code
  • Reconfirmation of diagnosis code.
Is the diagnosis code set?
Replace the engine-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
