Test DH: Step 91

91) Measure TP Circuit Voltage While Exercising TPS  Turn key off and wait 10 seconds. Disconnect ECA 60-pin connector. Inspect for and repair any damaged wiring. Install breakout box, leaving ECA connected. Stay in KOEO Continuous Monitor Mode (Wiggle Test) as in previous step. Connect DVOM between test pins No. 47 and 46. Set DVOM on 20-volt scale. With KOEO, observe DVOM and repeat step 90). If fault occurs at less than 4.25 volts, inspect TPS connectors and terminals. If okay, replace TPS, clear codes and repeat QUICK TEST. If fault does not occur at less than 4.25 volts, TPS over-travel may have caused Continuous Memory Code 53. TPS is okay, go to next step to check harness.
