hey guys goodmorning , i was wondering if any can help with a code 43, i dont know what can be wrong, i know its fuel supply. any help will be appreciated

 

Not seeing a 43 in my book or the online manual I often reference. Could be a 4 and a 3. These would definitely mess with your fuel and timing.


Code 4 is the crank angle sensor. if you're sohc, it's in the distributor. if you have a dohc zc, it is the sensor on the exhaust cam.

Code 3 is manifold absolute pressure, so look into the MAP sensor on the firewall.

Hopefully these pages help. Good luck.

 

Is the car in safe mode?

 

i had that too when i ran a integra ecu in my stock crx si. i think its something about not getting enough fuel or something. not positive on what it was.

 

pretty sure it is 4 & 3

 

no guys its 43 man im running a p28 ecu on a 94 zcvtec motor, im just trying to find out, 43=fuel supply

 

Probably would have helped to say that in your orignal post...lol. I figured since you didn't say otherwise, you had a si/zc variant using a stock or similar ecu.

come on guys. back on track there is a code 43.
also RACERX72, does the code go away for a while(like a week or two) then out of nowhere it comes back?
