Test DH: Step 6

6) Checking TP Circuit For Short to Power  Turn key off and wait 10 seconds. Disconnect TPS from harness. Set DVOM on 200-k/ohm scale. Disconnect ECA 60-pin connector. Inspect for and repair any damaged wiring. Install breakout box, leaving ECA disconnected. Measure resistance between test pin No. 47 and test pins No. 26 and 57. If either reading is less than 10 k/ohms, repair short in harness, connect components and repeat QUICK TEST. If both readings are 10 k/ohms or more, replace ECA, reconnect components and repeat QUICK TEST.

NOTE: There is a break in the step numbering sequence at this point, skipping from step 6) to step 10). Break is due to previous chart references to these testing procedures. No test procedures have been omitted.
