Test TC: Step 1

1) Code 67: Check Resistance Through MLP Sensor  Code 67 indicates that total resistance in the MLP sensor is out of Self-Test range when the selector lever is in "P" (correct range is 3770-4607 ohms). Possible causes for this fault are: faulty MLP sensor, open or shorted harness, faulty ECA.

Turn key off and wait 10 seconds. Disconnect ECA 60-pin connector and inspect for corroded or damaged pins. Service or repair as necessary. Install breakout box, leaving ECA disconnected. Set DVOM on 10 k/ohm scale. With KOEO, measure resistance between test pins No. 30 and 46 at the breakout box while moving the selector from "P" to "L" and back to "P". Record specifications and compare to specification table. If resistance is within specification, go to step 3). If resistance is not as specified, go to next step.
