Diagnostic procedure
STEP INSPECTION ACTION
1 PERFORM DTC CONFIRMATION PROCEDURE
• Perform DTC CONFIRMATION PROCEDURE.
(See F66 DTC CONFIRMATION
PROCEDURE.)
• Is same DTC present?
Yes Go to next step.
No Intermittent concern exists. Go to INTERMITTENT
CONCERN TROUBLESHOOTING procedure.
(See F227 INTERMITTENT CONCERN
TROUBLESHOOTING.)
2 VERIFY MAP PID WHEN MAP SENSOR
CONNECTOR IS DISCONNECTED
• Disconnect MAP sensor connector.
• Is voltage above 4.9 V?
Yes Go to next step.
No Go to step 4.
3 INSPECT POWER SUPPLY CIRCUIT VOLTAGE
AT MAP SENSOR CONNECTOR
Note
• If DTC P0122 and P2228 are also retrieved
with P0107, go to CONSTANT VOLTAGE
troubleshooting procedure.
• Turn ignition key to ON (Engine OFF).
• Measure voltage between MAP sensor
terminal C (harness-side) and body ground.
• Is voltage within 4.55.5 V?
Yes Check for poor connection of MAP sensor terminal C
(harness-side).
• Repair or replace terminal if necessary.
• If okay, replace MAP sensor.
Then go to Step 6.
No Check for open circuit between PCM terminal 2K (harness-
side) and MAP sensor terminal C (harness-side).
Repair or replace suspected harness, then go to Step 6.
4 INSPECT MAP SENSOR SIGNAL CIRCUIT FOR
SHORT TO GROUND
• Turn ignition key to OFF.
• Disconnect PCM connector.
• Inspect continuity between MAP sensor
terminal D (harness-side) and body ground.
• Is there continuity?
Yes Repair or replace suspected harness, then go to Step 6.
No Go to next step.
