Midnight F-117A

Hi,
Last week I got a SES light, did a PCM reset and the next drive the SES light came back.

I went to AutoZone and they ran a scan tool on it, it showed up P0327. I had them delete it and about 180 miles later it showed up again.

I looked up and it showed up as P0327 Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor)


There's two knock sensors under the intake mainfold, how do I know which one is at fault? Knock Sensor 1 circuit low input means it's a faulty sesnor?

I believe sensor 1 is the one closest to the radiator, connects to the back one through the harness with a connector under the intake.

yeah, it's the front one, closest to the radiator
more than likely its gonna need to be replaced, just gotta pull the intake and it's right there.
did you wash your engine down lately?...that was what killed mine, i didn't dry it.

Over a month ago. It didn't occur after that.
I have 114k on my b!tchin camaro and still going. In for the long haul!

I found out it's only about 30 bucks for a new knock sensor. I'm gonna go to the dealership tomorrow to order it.

If your in for the long haul, and going through the trouble of removing the intake, I'd replace both sensors...and never wash my engine again.

Just replaced the front knock sensor. Dealer had it in stock and I got it for $33.

Took me 3 hours from pulling the STB and the fuel rails and pulling the intake mainfold and all back together running.

The old one was rusted on the outside casing, the threads were clean.

Cleaning air filter now...
