hey do you guys know what is CEL code 43 on a 1991 honda accord lx, and how to diagnose the problem?thnkz

 

Find someone with a code scanner?

 

i thought only years 96 and up (OBDII) can put in the scanner. anyways not so long ago i saw a thread where it had all of the info that i need but now i can't seem to find it, is there someone that has the proceedure to find out the exact problem if the code is # 43 (Fuel Supply System
defective or malfunctioning fuel supply system).

 

Advance Auto has an OBDI and II scanner.

 

Neither one will do this car any good.

Code 43 indicates a problem in the fuel supply system or a problem in the oxygen sensor circuit.

I would go with the O2 sensor.
