Test DA: Step 22

22) Check Temperature Sensor Signal For Shorts to Ground  Turn key off and wait 10 seconds. Disconnect suspect sensor. Disconnect ECA 60-pin connector. Inspect for and repair any damaged wiring. Install breakout box, leaving ECA disconnected. Set DVOM on 200-k/ohm scale. Measure resistance between test pin No. 7 (ECT) or test pin No. 25 (ACT and VAT) and test pins No. 40, 46, and 60. If any reading is less than 10 k/ohms, repair short circuit. Remove breakout box, reconnect components, and repeat QUICK TEST. If all readings are 10 k/ohms or more, replace ECA. Remove breakout box and reconnect components. Repeat QUICK TEST.
