code 43

What is the** oops

it is a knock sensor issue. it could be the wiring, connector or the sensor itself.

if you have a scan tool, monitor the timing and then tap on the top of the motor with a hammer and it should retard 4 degrees.

Roy

Knock sensor is new, would the diagnostic test read a bad knock sensor? Like show up as knock sensor?

Its already retarding at 4degrees too

a code number never identifies a bad part, just a failed system.

if the timing is 4 retarded, disconnect the sensor and see if it advances to where it should be.

Roy

Where should it be?

It came to a steady 4 degrees , then i pressed the gas and it jumped again ffrom 4 to 2 to 3 to 4

how did you know is was 4 degrees retarded if you dont know where it should be??

4 degrees before top dead center is the spec.

Roy

Its just stopped at zero

how did you check the timing and when did you check it??

Roy

The diagnostic tester said it was at 4degrees, is that not what you meant?
Top dead center?

I didnt chk the timing? Im doin what the computers tellin me to do

The sticker on my truck under the hood says 0degrees

do you have a timing light to check it??
