as the title says my car starts throwing codes 23 and 43 after just a few minutes of driving- never on startup and even on warm starts.

23 is obviously the knock but i know its not knocking so im going to check the wiring for that. hoping maybe its related and if i fix one it will fix the other.

43 is the fuel supply system which has my clueless because it isnt running bad at all- runs very well actually.

Ive had a problem with one of my o2 sensor wires coming loose but in the past it has just thrown the o2 code when this has happened. could this be the reason for my code 43? could a code 43 set off the knock somehow?

any help would be GREATLY appreciated because im supposed to leave on vacation in about 12 hours.

 

knock sensor was unplugged. both codes are gone

 

thanks for posting your finding!

 

no problem at all.. i always try to post the solution whether i found it on here or not in case someone else has the same problem down the road

 

im getting to code 27 and i was just woundering were you guys look them up?
