DC14 - Check Continuity of MAF and VPWR Circuits

- Key "OFF".

- Disconnect sensor.

- Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.

- Install breakout box, leave PCM disconnected.

- Measure resistance between VPWR circuit at the Mass Air Flow (MAF) sensor vehicle harness connector and test pins 37 and 57 at the breakout box.

- Measure resistance between MAF circuit at the MAF sensor vehicle harness connector and test pin 50 at the breakout box.

- Is each resistance less than 5.0 ohms?

Yes -- Go to DC15. DC15 - Check MAF Circuit For Shorts to GND and MAF RTN Circuit

No -- Service open circuit. Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
