Test DF: Step 5

5) Check MAP/BP SIG Circuit For Shorts to VREF, SIG RTN & Ground Turn key off and wait 10 seconds. Disconnect ECA 60-pin connector. Inspect for and repair any damaged wiring. Install breakout box, leaving ECA disconnected. Disconnect harness at MAP/BP sensor. Set DVOM on 200-k/ohm scale. Measure resistance between test pin No. 45 and test pins No. 26, 46, 40, and 60. If any reading is less than 10 k/ohms, repair short circuit. Remove breakout box and reconnect all components. Repeat QUICK TEST. If all readings are 10 k/ohms or more, replace MAP/BP sensor. Remove breakout box and connect all wiring. Repeat QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 5) to step 7). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
