Test TC: Step 3

3) Check MLP Harness For Short To Power Or Ground  Turn key off. Ensure MLP sensor harness is disconnected. Install breakout box leaving ECA disconnected. Set DVOM on 200-k/ohm scale. Measure resistance between test pin No. 30 and test pins No. 37 and 57 at the breakout box. Measure resistance between test pin No. 30 and test pins No. 40, 46 and 60 at the breakout box. Measure resistance between test pin No. 30 at the breakout box and chassis ground. If all resistances are greater than 10 k/ohms, go to next step. If resistances are less than 10 k/ohms, repair short circuits, remove breakout box, reconnect components and rerun QUICK TEST.
