1995 Prelude vtec
OBD1

code 1 : o2 sensor most likely due to SEA FOAM

code 43? Fuel supply?


can i drive the car? it drives fine!!?!?

im replacing the o2 asap, but will the other cel go off too?

 

is it ok to drive the car?

the CEL comes on after bout 5 minutes of drviing

 

you'll be fine driving around like that, but your gas milage wont be that great. it shold go away once u replace your o2.

 

just reset ecu and drove a round for ab it.. the light didn't come on for a while.. then it cam eon so read the code

ONLY code 43!?!
wierd?!?!

 

Sea Foam
Just kidding, I had the same issues when I foamed my car. I pulled and cleaned the O2 sensor, and used some techron gas for a while and it eventually stopped popping up.

 

code 43 is a bad o2 sensor. trust me, seafoam or not.

 

after i replaced my O2 sensor i got code 43 also it comes on if the car is started cold once it warms up. If you turn the car off and back on again it doesnt come back on and from doing that my gas milage is the same. In the service manual it states that it is most likely a wiring problem and they give a flow chart on how to fix the problem but i havent gotten around to it yet.

 

When I used a Bosch replacement o2 I still got the code. Once I switched to the Ntk the code went away. Just be careful what O2 sensor you get or it might not fix the problem.

 

ij ust replaced my o2 sensor and I still get teh code 43 after drviign for 15 minutes or so..

im pretty sure its killing my gas milege

43 can be a few things; it's the catch-all fuel code.

On my last motor, I would occasionally get 43 out of nowhere, but it drove fine and would go away for a long time if I reset it. If i tuned the VAFC's narrow-throttle settings and it threw the code as well.

My new motor is throwing it now, and it sounds like an injector cutting out when I give it gas. The manual says it can be bad gas, an injector, or the FPR. I've also heard of the fuel filter causing this problem.

Go figure.

 

maybe my vafc is fking up im not sure


but i want this fixed asap! anyoen else have ideas
