Hello, I have an 09 hyundai accent, it started running funny and through the p0328 code so I put in a new knock sensor. That didn't work so I checked the wires going to it. It has 2 wires a yellow and a brown both have 2.4 ish volts. I went to the ecu and checked them there to see if it would have 2.4v there as well and it did. Does this mean my ecu is the issue?
