DTC P0106 [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)]

id0102c4954000

DTC P0106

Boost sensor range/performance malfunction
DETECTION CONDITION
•  The PCM monitors and compares the intake manifold internal pressure via the boost sensor with the atmospheric pressure via the barometric pressure sensor (built into PCM) while the engine is not running. If the difference of these pressure is above 11 kPa {0.11 bar, 1.6 psi}, the PCM determines that there is a boost sensor characteristic malfunction.
Note
•  If DTCs P0106 and P2227 are recorded simultaneously, the PCM determines that there is a boost sensor and barometric pressure sensor characteristic malfunction.
POSSIBLE CAUSE
•  Boost sensor malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has 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 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
VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT?
•  Connect the M-MDS to the DLC-2.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Is the same DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”.
(See INTERMITTENT CONCERN TROUBLESHOOTING [WL-C, WE-C].)
4
INSPECT BOOST SENSOR
•  Inspect the boost sensor.
•  Is there any malfunction?
Yes
Replace the boost sensor, then go to Step 7.
No
Go to the next step.
5
VERIFY TROUBLESHOOTING OF DTC P0106 COMPLETED
•  Turn the engine switch off.
•  Make sure to reconnect all disconnected connectors.
•  Turn the engine switch to the ON position (Engine off).
•  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
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [WL-C, WE-C].)
(See PCM REMOVAL/INSTALLATION (U.K. Specs.) [WL-C, WE-C].)
No
Go to the next step.
6
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “After Repair Procedure“.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [WL-C, WE-C (Australian, European (L.H.D. U.K.) specs.)].)
No
DTC troubleshooting completed.
