Diagnosis Procedure

ECM input/output valve when the engine control system operates normally.

NOTE:

The SP value is indicated when “DISPLAY TYPE” is “Line Graph”.

The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the MIL.

The SP value will be displayed for the following three items:

• Base fuel schedule (The fuel injection pulse width programmed into ECM prior to any learned on board correction)

• Air fuel ratio compensation (bank 1) (The mean value of air-fuel ratio feedback correction factor per cycle)

• MASS AIR FLOW SENSOR (Hz) B1 (The signal frequency of the mass air flow sensor)
