Test DN: Step 92

92) Measure EVP Signal Voltage While Exercising EVP Sensor  Turn key off and wait 10 seconds. Disconnect ECA 60-pin connector. Inspect connector and terminals for obvious damage. If connector and terminals are damaged, repair as necessary. Install breakout box and reconnect ECA. Set DVOM on 20-volt scale and connect DVOM between test pins No. 27 and 46. Re-enter KOEO Continuous Monitor Mode (Wiggle Test). Observe DVOM while repeating test step 91). If the fault occurs at less than 4.25 volts, disconnect and inspect connector. If connector is okay, replace EVP sensor. Clear codes and repeat QUICK TEST. If fault does not occur at less than 4.25 volts, go to next step.
