Since various components need to be monitored in different driving conditions, the OBD II system is designed to run separate monitoring programs called Readiness Monitors.
HINT:
Many Inspection and Maintenance (I/M) programs require a vehicle's Readiness Monitor status to show COMPL before beginning emission tests.
The Readiness Monitor will be reset to INCMPL (incomplete) if:
If the Readiness Monitor status shows INCMPL, follow the appropriate Readiness Monitor Drive Pattern to change the status to COMPL.
CAUTION: Strictly observe posted speed limits, traffic laws, and road conditions when performing these drive patterns. |
NOTICE: These drive patterns represent the fastest method of satisfying all conditions necessary to achieve complete status for each specific Readiness Monitor. In the event of a drive pattern being interrupted (possibly due to factors such as traffic conditions), the drive pattern can be resumed. In most cases, the Readiness Monitor will still achieve complete status upon completion of the drive pattern. To ensure completion of the Readiness Monitors, avoid sudden changes in vehicle load and speed (driving up and down hills and/or sudden acceleration). |
Inspection
1. INSPECT MASS AIR FLOW METER
Visually check for any foreign matter on the
platinum hot wire (heater) of the mass air flow
meter.
OK:
There is no foreign matter.
If the result is not as specified, replace the mass air
flow meter.
Measure the resistance according to the ...
