I hit a HUGE pothole this morning on the way to work, a few seconds later my CEL came on. I did the E1 Te1 bridge to run the diagnostic and it threw out a 52. I looked in the bgb guide and found that was the knock sensor.

All good so far.

But, where is it exactly. Is it likely I got knocked (forgive the pun) loose by the impact? Is it easy to get to? I hate driving around with my cel on.

Did the CEL come back after getting the code and clearing it?

Good question. I just jumped the diagnostic port and got the code. In fact when I started the engine the CEL wasn't on any more but when I ran the diagnostic the code came through. How would i clear it? Don't I need to remove the EFI 15A fuse or something or does running the diagnostic clear it?

I just drove her around the parking lot of my work a little, revved the engine some, and no CEL came on.

I should also say I put a new ignition coil in a couple of days ago but didn't check my timing afterwards because I didn't have a timing light handy. I will be doing so later today. Could that be related at all?

It was just very obvious that the CEL came on right after I hit the huge pot hole.

yeah, most likley your knock sensor picked up that pothole a bit. reset your ecu by doing the fuse removal or battery disconect thing. if it pops back on your sensor is on the back of the engine block with 1 wire comming out of it. prob needs a replace, go to junkyard for it. the coil wont affect your timing. just watch it for awhile if it stays off then your prob fine.

52 is a short.

That pothole knocked your sensors plug out.

52 isnt cause it "registered knock" andy.

Its under the intake manifold

Thanks. It's just great to be able to tap this knowledge pool on here.

The word awesome is constantly over used in common parlance but I can safely say with a complete degree of certainty that this place is, indeed, awesome.
