DTC P0107
A6E397001084W11
3 INSPECT MAF SIGNAL CIRCUIT FOR SHORT
TO POWER CIRCUIT
• Turn ignition key to ON (Engine OFF).
• Measure voltage between MAF/IAT sensor
terminal C (harness-side) and body ground.
• Is there voltage 0 V?
Yes Go to next step.
No Repair or replace suspected harness, then go to Step 6.
4 INSPECT POOR CONNECTION OF PCM
CONNECTOR
• Turn ignition key to OFF.
• Disconnect PCM connector.
• Inspect for poor connection (damaged, pulled-
out terminals, corrosion, etc.).
• Is there any malfunction?
Yes Repair terminal, then go to Step 6.
No Go to next step.
5 INSPECT MAF SENSOR GROUND CIRCUIT
FOR OPEN CIRCUIT
• Remove PCM with PCM connector connected.
• Inspect for continuity between MAF/IAT sensor
terminal B (harness-side) and GND.
• Is there any continuity?
Yes Replace MAF/IAT sensor, then go to next step.
No Repair or replace suspected harness, then go to next step.
6 VERIFY TROUBLESHOOTING OF DTC P0103
COMPLETED
• Make sure to reconnect all disconnected
connectors.
• Clear DTC from memory using WDS or
equivalent.
• Perform KOEO/KOER self-test.
(See F66 KOEO/KOER SELF-TEST.)
• Is same DTC present?
Yes Replace PCM, then go to next step.
(See F43 PCM REMOVAL/INSTALLATION.)
No Go to next step.
7 VERIFY AFTER REPAIR PROCEDURE
• Perform After Repair Procedure.
(See F66 AFTER REPAIR PROCEDURE.)
• Is there any DTC present?
Yes Go to applicable DTC troubleshooting.
(See F67 DTC TABLE.)
No Troubleshooting completed.
STEP INSPECTION ACTION
DTC P0107 MAP sensor circuit low input
DETECTION
CONDITION
• PCM monitors input voltage from MAP sensor when intake air temperature is above 10 °
°°
°C {50 °
°°
°F}. If input
voltage at PCM terminal 1J is below 0.1V, PCM determines that MAP sensor circuit has a malfunction.
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 available if PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.
POSSIBLE
CAUSE
• MAP sensor malfunction
• Connector or terminal malfunction
• Short to ground in wiring between MAP sensor terminal D and PCM terminal 1J
• Open circuit in wiring between MAP sensor terminal C and PCM terminal 2K
• MAP sensor signal circuit and MAP sensor ground circuit are shorted each other
• PCM malfunction
