Message code 34 temporarily. It's being thrown because their is a problem with your
knock sensor or more likely the harness leading to it, or the harness from
the main EFI harness leading to the knock sensor connector, i.e. the
wiring has broken. Often you can repair the wiring by splicing it back
together if the broken spot is accessible. The harness connector is at the
back middle of the engine sticking up vertically on a bracket.

Here's a link to where it's located:

If it is a problem with the sensor itself then you can relocate it to the top of
the engine because it's current location is inaccessible with the engine in
the car for all intents and purposes. Search "detonation sensor relocation"
on this site for more info.

Also search "short term code 34"
