NF-1A

Note: Perform TEST DR-1A before proceeding.

1. Check for Technical Service Bulletins and manual updates that are related to the symptoms.

2. Perform NO FAULT QUICK TEST (individual test only).

Note: These tests are grouped by PCM inputs, outputs, and non-monitored categories.

INPUTS OUTPUTS NON-MONITORED

Coolant Idle Speed Motor Secondary Ignition
TPS EGR Fuel Pressure
MAP Engine Vacuum
O2 Sensor Min. Idle Air Flow
P/N Switch Engine Mechanical

3. If you suspect any of the above items to be the cause of the driveability problem, perform the associated test(s). Otherwise perform TESTS NF-2A through NF-13A, in sequence until the problem is located.

Note: The following tests check for conditions which will cause a driveability problem but will not set a hard fault [1].

Checking Secondary Ignition And Timing NF-2A
Checking Fuel Pressure NF-3A
Checking Coolant And Tps Calibrations NF-4A
Checking Map Sensor Calibration NF-5A
Checking Oxygen Sensor Switching NF-6A
Checking Idle Speed Motor Operation NF-7A
Checking Park/neutral Switch (at Only) NF-8A
Checking PCM Grounds NF-9A
Checking EGR Valve Operation (if equipped) NF-10A
Checking Engine Vacuum NF-11A
Checking Minimum Idle Air Flow NF-12A
Checking Engine Mechanical NF-13A

Remarks:

[1] Hard fault - key cycle counter is on 0.
