DTC P0107 [AJ]

BME010200100205

DTC P0107 | BARO sensor/EGR boost sensor circuit low input
--- | ---
DETECTION CONDITION | • PCM monitors input voltage from BARO sensor/EGR boost sensor when monitoring conditions are met. If input voltage at PCM terminal 34 is below 0.2 V, PCM determines that BARO sensor/EGR boost circuit is malfunctioning. MONITORING CONDITION

  - Intake air temperature is above 10 °C {50 °F}.
  - EGR boost sensor solenoid is turned OFF. (Barometric pressure is applied to EGR boost sensor.) (Australian, General (L.H.D. R.H.D.))

Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if PCM detects the above malfunction condition during first drive cycle.
• PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.
POSSIBLE CAUSE | • BARO sensor/EGR boost sensor malfunction • Connector or terminal malfunction • Short to ground in wiring between BARO sensor/EGR boost sensor terminal B and PCM terminal 34 • Open circuit in wiring between BARO sensor/EGR boost sensor terminal C and PCM terminal 90
• 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 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 | VERIFY CURRENT INPUT SIGNAL STATUS-IS CONCERN INTERMITTENT OR CONSTANT • Connect the WDS or equivalent to the DLC-2. • Start engine. • Access BARO PID. • Is BARO PID below 0.2 V? | Yes | Go to the next step.
No | Intermittent concern exists. Go to INTERMITTENT CONCERNS TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [AJ].)
4 | VERIFY BARO PID WHEN EGR BOOST SENSOR CONNECTOR IS DISCONNECTED • Disconnect the BARO sensor/EGR boost sensor connector. • Is voltage above 4.8 V? | Yes | Go to the next step.
No | Go to step 6.
5 | CHECK POWER SUPPLY CIRCUIT VOLTAGE AT BARO SENSOR/EGR BOOST SENSOR CONNECTOR

  Note

  • If DTC P0122 is also retrieved with P0107, then go to CONSTANT VOLTAGE troubleshooting procedure.

• Turn the ignition switch to the ON position (Engine off).
• Measure the voltage between BARO sensor/EGR boost sensor terminal C (wiring harness-side) and body ground.
• Is there voltage within 4.5- 5.5 V?
Yes
Inspect for poor connection of BARO sensor/EGR boost sensor terminal C (wiring harness-side).
• Repair or replace terminal if necessary.
• If normal, replace the BARO sensor/EGR boost sensor.
Then go to Step 8.
No | Inspect for open circuit between PCM terminal 90 (wiring harness-side) and EGR boost sensor terminal C (wiring harness-side). Repair or replace the wiring harness, then go to Step 8.
6 | INSPECT BARO SENSOR/EGR BOOST SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for continuity between BARO sensor/EGR boost sensor terminal B (wiring harness-side) and body ground.
• Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 8.
No | Go to the next step.
7 | INSPECT BARO SENSOR/EGR BOOST SENSOR SIGNAL AND GROUND CIRCUIT FOR SHORT TO EACH OTHER • Inspect for continuity between BARO sensor/EGR boost sensor terminals B and A (harness-side). • Is there continuity? | Yes | Repair or replace the wiring harness, then go to the next step.
No | Go to the next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0107 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. • Start the engine.
• Access IAT PIDs using WDS or equivalent.
• Make sure that IAT PID is above 10 °C {50 °F}
• 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.
