DTC P0106 [AJ]

BME010200100204

## Australian, General (L.H.D. R.H.D.) Specs.

DTC P0106 | EGR boost sensor circuit performance problem
--- | ---
DETECTION CONDITION | • PCM monitors differences between intake manifold vacuum and atmospheric pressure at idle, which EGR boost sensor detects by switching EGR boost sensor solenoid. If difference is below 6.43 kPa {48.2 mmHg, 1.90 inHg}, PCM determines that there is a EGR boost sensor performance problem. Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles.
• PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.
POSSIBLE CAUSE | • EGR boost sensor malfunction or substandard performance • EGR boost sensor solenoid malfunction • Loosed, damaged, misconnected, clogged or frozen moisture in vacuum hose from EGR boost sensor solenoid to EGR boost sensor • Loosed, damaged, misconnected, clogged or frozen moisture in vacuum hose from EGR boost sensor solenoid to EGR pipe

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 FREEZE FRAME DATA on repair order, then go to the next step.
2 | VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to available Service Information. • If vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is DTC P0106 on FREEZE FRAME DATA? | Yes | Go to the next step.
No | Go to troubleshooting procedures for DTC on FREEZE FRAME DATA.
4 | INSPECT CONNECTION OF EGR BOOST SENSING RELATED VACUUM HOSES • Inspect the following vacuum hoses for loose, damage, improper connection and/or clog.

  - From EGR boost sensor to EGR boost sensor solenoid
  - From EGR boost sensor solenoid to EGR pipe

• Are they normal?
Yes
Go to the next step.
No | Repair or replace the vacuum hose, then go to Step 8.
5 | INSPECT EGR BOOST SENSOR SOLENOID AIR FILTER FOR CLOG • Has EGR boost sensor solenoid air filter been clogged? | Yes | Repair air clogging, then go to Step 8.
No | Go to the next step.
6 | INSPECT EGR BOOST SENSOR SOLENOID FOR STUCK OPEN OR CLOSED • Inspect the EGR boost sensor solenoid. (See EGR BOOST SENSOR SOLENOID VALVE INSPECTION ( AUSTRALIAN, GENERAL (L.H.D. R.H.D.) SPECS.) [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).)
• Is the EGR boost sensor solenoid normal?
Yes
Go to the next step.
No | Replace the EGR boost sensor solenoid, then go to Step 8.
7 | INSPECT EGR BOOST SENSOR FOR STUCK OPEN OR CLOSED • Inspect the EGR boost sensor. (See BAROMETRIC PRESSURE SENSOR/EGR BOOST SENSOR INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).)
• Is the EGR boost sensor normal?
Yes
Go to the next step.
No | Replace the EGR boost sensor, then go to the next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0106 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the WDS or equivalent. • Run PCM adaptive memory procedure drive mode and HO2S heater, HO2S, and EGR system repair verification drive mode.
(See OBD DRIVE MODE [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).)
• Stop vehicle.
• Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No | Go to the next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [AJ].) • Is there any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).)
No | Troubleshooting completed.
