no issues with driving. speedometer also giving accurate read (tested against a gps). i am due for an inspection and in general would like to keep the car in good health. i switched the knock sensor a year ago and the check engine light deleted the codes and it stayed off. About 3 months ago it gave me the output speed sensor code, i put in a new sensor - it didn't help. The knock sensor code came about a month after that.

Let's start with getting the actual codes that you have and then we can provide the testing and info needed to figure this out.

In the meantime, here are a couple guides that will help with this info of each system:

I assume we are going to be dealing with a wiring issue or a control module but let's start with getting the actual codes and we can go from there.

Thanks
