hi... i have a 93 accord ex coupe... i had the oxygen sensor changed last weekend and it was running great till last night... the engine light went on and when i diagnosed it it showed code 43 again.... i had the same problem for the past months.... it keeps coming back.... also the ABS light was also lit.... it showed code 12..... guys please help me on this one..... i've been spending a lot already with that oxygen sensor..... thank you guys in advance....

 

Aftermarket or OEM sensor? I have seen problems with some aftermarket sensors not working at all or not for very long. And, did you replace the correct sensor?

 

the brand of the sensor is denso.... i guess its an aftermarket.... before i use bosch but it didn't last long.... everytime the engine light goes on the car becomes sluggish.... its like there's no power then suddenly it will have power again.... its like being choked then when i step on the gas hard it will power up again.... i replaced the sensor before the catalytic converter.... is there another sensor? i'm planning on replacing the fuel pump as the last resort coz i've changed the distributor cap, rotor, and fuel filter and the oxygen sensor but not the fuel pump..... what do you guys think?

 

anybody? i'm planning to go on a long drive this weekend.... please help me on my problem.... thanks....
