Test TC: Step 4

4) Checking ECA Output Voltage  Ensure key is off. Disconnect MLP sensor from harness. Install breakout box and connect ECA. With KOEO, set DVOM on 20-volt scale. Measure voltage between test pins No. 30 and 46 at the breakout box. If voltage is 4.75-5.25 volts, service or adjust MLP sensor. If voltage is not as specified, replace ECA, reconnect components and rerun QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 4) to step 10). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
