DTC DETECTION LOGIC
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0101 | MAF SEN/CIRCUIT-B1 (Mass or volume air flow “A” circuit range/performance) | An excessively high voltage from the mass air flow sensor is sent to ECM. |
|
P0102 | MAF SEN/CIRCUIT-B1 (Mass or volume air flow “A” circuit low input) | An excessively low voltage from the mass air flow sensor is sent to ECM. |
|
P0103 | MAF SEN/CIRCUIT-B1 (Mass or volume air flow “A” circuit high input) | An excessively high voltage from the mass air flow sensor is sent to ECM. |

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
Which DTC is detected? P0102 >> GO TO 2.
P0101 or P0103>>GO TO 3.
2.PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P0102
Is DTC detected? YES >> Proceed to EC-187, "Diagnosis Procedure".
NO >> INSPECTION END
3.PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P0101 AND P0103-1
Is DTC detected? YES >> Proceed to EC-187, "Diagnosis Procedure".
NO >> GO TO 4.
4.PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P0101 AND P0103-2
Is DTC detected? YES >> Proceed to EC-187, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.INSPECTION START
Confirm the detected DTC.
Which DTC is detected? P0102 >> GO TO 2.
P0101 and P0103>>GO TO 3.
2.CHECK INTAKE SYSTEM
Check the following for connection.
Is the inspection result normal? YES >> GO TO 3.
NO >> Reconnect or replace error-detected parts.
3.CHECK MASS AIR FLOW (MAF) SENSOR POWER SUPPLY
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 7.
4.CHECK MAF SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK MAF SENSOR INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts
6.CHECK MAF SENSOR
Check the MAF sensor. Refer to EC-188, "Component Inspection (MAF Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace MAF sensor (with intake air temperature sensor). Refer to EM-25, "Exploded View".
7.CHECK MAF SENSOR POWER CIRCUIT
Is the inspection result normal? YES >> GO TO 8.
NO >> Repair or replace error-detected parts.
8.CHECK SENSOR POWER SUPPLY 2 CIRCUIT
Check sensor power supply 2 circuit. Refer to EC-444, "Diagnosis Procedure".
Is inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
Component Inspection (MAF Sensor)
1.CHECK MASS AIR FLOW SENSOR-1
With CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Without CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Is the inspection result normal? YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK FOR THE CAUSE OF UNEVEN AIR FLOW THROUGH MASS AIR FLOW SENSOR
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK MASS AIR FLOW SENSOR-2
With CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Without CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Is the inspection result normal? YES >> INSPECTION END
NO >> GO TO 4.
4.CHECK MASS AIR FLOW SENSOR-3
With CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Without CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Clean or replace mass air flow sensor. Refer to EM-25, "Exploded View".
