Just purchased Autel 329. Read code P0327 to verify Knock Sensor. Nice cheap scanner.

 

327 is either an open or a circuit short in the wiring to the Sensor.
Be careful about interpretation without looking up the full code description and may not clear until doing a drive cycle so the PCM can test it. It's one of a few codes that cannot be cleared until repaired and tested to PCM satisfaction.
This and an over-heat fault are treated as very serious for engine damage.
Good luck.

 

The service advisor didn't seem to concerned. That is what he told me and I just verified that it was a knock sensor code. Don't know what else to do unless I take it to an open shop, seems they are on backorder from Ford.

 

I'm just trying to help you see that these vehicles are not simple to work on with any background and without sounding insulting so many far too quickly, jump on me for.
I can't say it in any other way.
Forscan and Scanners are nice to see there are fault codes, but it does not fill in for knowledge of what to do about them.
Good luck.

 

The knock sensors finally came in but the service advisor called and told me they have to order hardware to complete sensor replacement. Does anyone know what hardware is need to replace knock sensor harness?
