Checking Mass Air Flow Sensor

Checking The Air Intake
- Check the air intake in front of the radiator, air duct, air cleaner (ACL) housing and cleaner insert for blockage (leaves, paper etc).
- Is the air intake OK?

Yes:
^ Proceed to test step below.

No:
^ Remedy as necessary.





Checking Mass Air Flow Sensor
- Ignition on.
- Mass air flow (MAF) sensor connected.
- Connect a voltmeter between mass air flow sensor connector terminals 2 and 4.
- The voltmeter should read 0.1 - 0.2 Volts.

If reading is OK:
^ Proceed to Checking Rotor, Distributor Cap, Spark Plugs section.

If reading is incorrect:
^ Fault-trace mass air flow sensor.
