Where is the knock sensor on 2009 1.8L Vibe?
I noticed my 2009 Vibe running a little rough one day, but it cleared up before i got home and I forgot about it. The next day I started out and ran through a deep puddle (which happens all the time), and several warning lights came on and stayed on. I took it back home and got my wife's car. It rained all week and i tried it a few times, but the lights stayed on. Things finally dried out and it should have been dry, but the lights stayed on. I dug out the code reader and got PO328, "Knock Sensor 1 circuit Bank 1 High Voltage"
A number of years ago warning lights like this lead to the dealer replacing the knock sensor for about $600. Then a few weeks later the same lights came on again and the dealer said that the computer was bad. I questioned this and they said the sensor probably damaged the computer. They replaced that for $600 or$800. (When the lights came on the second time there was a car behind me n the highway with Sapaugh 7 (the dealer) license plates. Good thing i'm not paranoid!)
Anyway, after i read the codes, I turned the cat back on intending to write down which lights were on, as I hadn't done that. The lights didn't come back on. I did not press the erase button on the reader.
I haven't driven it yet, but probably will try today.
Anybody have any idea what might be happening, whether I should look at replacing the knock sensor, and how to do that?
