1996 Chevrolet Blazer 4.3L MIL Lamp on
Repair info I have from 2 sources says that knock sensor should drag 5V reference voltage in circuit down to about 2.5 volts. It is 4.5V. Sensor resistance is 100 K-ohms (correct as per Alldata). Does the high voltage reading mean that the knock sensor is bad?
