I have a code 43 on my check engine light on my '93 Chevy truck that has a 5.7 and according to a local automotive parts house I should check the knock sensor and associated wiring for loose connections and such. Where is the knock sensor and how would I check it?

KNOCK SENSOR
WE HAVE A VERY SIMILAR TRUCK. :cheers:
YOUR KNOCK SENSOR SHOULD BE DIRECTLY IN FRONT OF THE STARTER, IT THREADS INTO THE SIDE OF THE BLOCK.
THE ONLY METHOD THAT I AM AWARE OF TO TEST IT IS:
-HOOK UP A TIMING LIGHT
-ENSURE YOUR TIMING IS CORRECT
-WHILE WATCHING THE TIMING, TAP ON THE BLOCK WITH SOMETHING METAL (TIMING SHOULD RETARD)
-IF NOT TAP HARDER :twak:
-IF IT STILL DOESNT RETARD, YOUR SENSOR IS PROBABLY BUNK
GOOD LUCK
