Mass Air Flow Sensor: Testing and Inspection
COMPONENT INSPECTION
Mass Air Flow Sensor
1. Turn ignition switch "ON".
2. Start engine and warm it up sufficiently.
3. Check voltage between terminal (1) and ground.
Conditions / Voltage V
Ignition switch "ON" (Engine stopped.) / Less than 1.0
Idle (Engine is warmed-up sufficiently.) / 1.0 - 1.7
Idle to about 4,000 rpm* / 1.0 - 1.7 to Approx. 4.0
*: Check for linear voltage rise in response to increases to about 4,000 rpm in engine speed.
4. If NG, remove mass air flow sensor from air duct. Check hot film for damage or dust.
