Test Dc: Step 12

12) Check Continuity of PWR GND Circuit  Ensure key is turned off and disconnect MAF sensor. Set DVOM on 200-ohm scale. Measure resistance between PWR GND circuit at MAF sensor vehicle harness connector and battery negative post. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open circuit, reconnect all components and repeat QUICK TEST. If resistance is 5 ohms or less, go to next step.
