so i threw a cel, and it turned out to be 43... c-speedracing.com says that 43 is:

43 92-95 Civic
90-95 Prelude
94+ Integra Fuel Supply System defective or malfunctioning fuel supply system

any idea what might be causing this? the car doesn't seem to be running in limp mode at all, and nothing else seems wrong with it. my only mods are aem intake and exhaust... any help would be much appreciated.

 

anyone?

 

It could be a whole lot of things...lemme peruse the Helms and see if I can't help ya out.

My Helms says (although this is from a G2, but probably the same): "Code 43: A problem in the Heated Oxygen Sensor circuit or a problem in the Fuel Supply System."

It's only the fuel system if you're having noticing something wrong with the drivability. Otherwise it's the O2 sensor.

First step is to see if ya can't just get rid of the code. As long as the car is running fine, here's what you should do:

-Reset the ECU
-Turn on the engine and let it run until the radiator fan comes on
-Hold the engine at 3000 RPM for 2 minutes

If the code comes on, you could either have a problem with the wiring somwhere in the circuit or a bad sensor.

 

i'll give that a try.. thanks mr fb

 

I get the same code as c-speedracing gives you, fuel malfunction. Try a bottle of Techron fuel cleaner. Are you in need of a new fuel filter? I changed mine at 30k miles. Do the easy obvious fule realted things first. Then reset the ECU and see if it still comes back.

Good luck!
