I'm still getting an ESC flag. If I drive normal for a while, once warm i stop at a light for example, floor it and SES light. I've logged and don't see any knock counts when the flag sets, nothing actually looks out of whack but i'm still new at this.

 

Do you ever get ANY knock counts? If not, your sensor or wiring may be bad.

The ECU should do a forced knock test, where it adds timing that should make it knock, just to see if the sensor is working. If no response, then it sets the SES.

 

last three lines in today's log show 11 knocks, probably when I turned it off. My other logs also show 0 knock, i guess i'll check the sensor or the wiring.

Thanks
