DTC P0299:00, P0299:84 [MZ-CD 1.6 (Y6) (EURO5 emission level)]

id0102g7445300

DTC P0299:00

DTC P0299:84

Turbocharger under boost condition
DETECTION CONDITION
•  The PCM monitors the actual boost pressure based on the MAP sensor signal and compares the target boost pressure with the actual pressure. If the actual boost pressure is less than the threshold determined by the target boost pressure based on the engine driving conditions the PCM determines that there is a turbocharger under-boost condition.
POSSIBLE CAUSE
•  Air leakage from intake-air system (between turbocharger and intake manifold)
•  Charge air cooler damaged
•  Poor connection or damaged vacuum hose at VBC solenoid valve and/or VBC valve actuator
•  VBC valve actuator stuck
•  VBC solenoid valve stuck close
•  Open circuit in wiring harness between VBC solenoid valve and PCM terminal 2AV
•  Short to power supply between VBC solenoid valve and PCM terminal 2AV
•  Turbocharger malfunction
•  Open or short circuit in wiring harness between MAP sensor and PCM
•  MAP sensor characteristic malfunction
•  PCM malfunction

Diagnostic procedure

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 RELATED PENDING CODE AND/OR DTC
•  Switch the ignition to OFF, then to ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Is the following PENDING CODE/DTC also present?
―  P0048:00, P0069:00, P0237:00, P0328:00
Yes
Go to the applicable DTC inspection.
(See DTC P0048:00 [MZ-CD 1.6 (Y6) (EURO5 emission level)].)
(See DTC P0069:00 [MZ-CD 1.6 (Y6) (EURO5 emission level)].)
(See DTC P0237:00 [MZ-CD 1.6 (Y6) (EURO5 emission level)].)
(See DTC P0238:00 [MZ-CD 1.6 (Y6) (EURO5 emission level)].)
No
Go to the next step.
4
INSPECT POOR INSTALLATION OR DAMAGED AT INTAKE-AIR SYSTEM AND MAP SENSOR
•  Inspect the intake-air system and the MAP sensor for following:
―  Loose installation (tube, hose, cramp)
―  Damaged or crack at tube and/or hose
•  Is there any malfunction?
Yes
Repair or replace malfunctioning part, then go to Step 11.
No
Go to the next step.
5
INSPECT VBC ACTUATOR VACUUM HOSE ROUTINE
•  Inspect the vacuum hose routine of the VBC actuator.
•  Is the vacuum hose routine properly?
Yes
Go to the next step.
No
Reconnect the vacuum hose properly, then go to Step 11.
6
INSPECT VBC ACTUATOR
•  Disconnect the vacuum hose from the VBC actuator.
•  Connect the vacuum pump and apply vacuum to the VBC actuator.
•  Does the VBC actuator rod move?
Yes
Go to the next step.
No
Replace the turbocharger, then go to Step 11.
(See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)
7
INSPECT VBC SOLENOID VALVE
•  Remove the VBC solenoid valve.
•  Apply the voltage is applied between terminals B and A at component-side connector.
•  Does the VBC solenoid valve operate?
Yes
Go to the next step.
No
Replace the VBC solenoid valve, then go to Step 11.
8
INSPECT VBC SOLENOID VALVE CONTROL SIGNAL CIRCUIT FOR OPEN OR SHORT TO POWER SUPPLY
•  Inspect for open or short to power supply circuit between VBC solenoid valve terminal A and PCM terminal 2AV.
•  Is there any malfunction?
Yes
Repair wiring harness for a possible open or short to power supply, then go to Step 11.
No
Go to the next step.
9
INSPECT MAP SENSOR CIRCUITS FOR OPEN OR SHORT CIRCUIT
•  Inspect for open or short circuit between following MAP sensor terminals and PCM terminals.
―  MAP sensor terminal A—PCM terminal 2AP
―  MAP sensor terminal B—PCM terminal 2T
―  MAP sensor terminal C—PCM terminal 2AS
•  Is there any malfunction?
Yes
Repair wiring harness for a possible open or short circuit, then go to Step 11.
No
Go to the next step.
10
INSPECT MAP SENSOR
•  Inspect the MAP sensor.
•  Is there any malfunction?
Yes
Replace the MAP sensor, the go to the next step.
No
Replace the turbocharger, then go to the next step.
(See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)
11
VERIFY THAT DTC P0299:00, P0299:84 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.
Go to the next step.
No
Go to the next step.
12
VERIFY AFTER REPAIR PROCEDURE
•  Perform the after repair procedure.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6 (Y6) (EURO5 emission level)].)
No
DTC troubleshooting completed.
