NO >> Repair or replace error-detected parts
7.CHECK INTAKE AIR TEMPERATURE SENSOR
Check the intake air temperature sensor. Refer to EC-207, "Component Inspection".
Is the inspection result normal? YES >> GO TO 8.
NO >> Replace MAF sensor (with intake air temperature sensor). Refer to EM-24, "Exploded View".
8.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
Check the EVAP control system pressure sensor. Refer to EC-330, "Component Inspection".
Is the inspection result normal? YES >> GO TO 9.
NO >> Replace EVAP control system pressure sensor. Refer to FL-22, "Removal and Installation".
9.CHECK MAF SENSOR
Check the MAF sensor. Refer to EC-200, "Component Inspection".
Is the inspection result normal? YES >> GO TO 10.
NO >> Replace MAF sensor. Refer to EM-24, "Exploded View".
10.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK MASS AIR FLOW SENSOR-1
With CONSULT
*: Check for linear frequency 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
Monitor item | Condition | Value |
MASS AIR FLOW SENSOR (Hz) | Ignition switch ON (Engine stopped.) | Approx. 3500 Hz |
Idle (Engine is warmed-up to normal operating temperature.) | 3500- 4100 Hz | |
2,500 rpm (Engine is warmed-up to normal operating temperature.) | 5000 - 5600 Hz | |
Idle to about 4,000 rpm | 3500 - 4100 Hz to Approx. 6300 Hz* |
*: Check for linear frequency 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
Monitor item | Condition | Value |
MASS AIR FLOW SENSOR (Hz) | Ignition switch ON (Engine stopped.) | Approx. 3500 Hz |
Idle (Engine is warmed-up to normal operating temperature.) | 3500- 4100 Hz | |
2,500 rpm (Engine is warmed-up to normal operating temperature.) | 5000 - 5600 Hz | |
Idle to about 4,000 rpm | 3500 - 4100 Hz to Approx. 6300 Hz* |
*: Check for linear frequency 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-24, "Exploded View".
Additional service when replacing TCM
Description
Always perform the following items when the TCM is replaced.
TCM PROGRAMMING
Since vehicle specifications are not yet written in a new TCM, it
is necessary to write them with CONSULT.
