Got a 91 Accord EX 2.2L. Had a few problems. One is check engine light the other was a no start condition that was very intermittent. Well, the no start turned out to be main relay, problem solved. Was hoping that code 43 would be fixed too, but I'm SOL on that one. Have a Haynes repair manual but the damn thing doesn't even list a code 43. What to do? Tested o2 and the only thing I could find was pins A and B were only reading 6 ohms instead of 15-20 like the book was reading. Any one got any suggestions. Thanks, Ron.

 

what mods have you done to your car? i've read a little about code 43 today because i just got it too

some things i was going to search more about:
fuel pump
fuel filter
looking at spark plugs (lean? rich?)

IF the car is stock and the fuel pressure stays in spec and there are no large vacuum leaks, the o2 sensor probably crapped.

Edit&gt; also check the o2 sensor, sometimes oil leaks run down the wires and contaminate it on ex models.

 

Consider the code to mean an incomplete fuel burn, the meaning was lost in translation I think.[fuel system my hairy butt] The real meaning of the code is the O2 sensor is seeing 'unburned' oxides. plugs okay? Air filter good?

 

poor valve adjustment can occasionally cause a 43 as well.
