I need help trying to figure out why my ecu is throwing this code.

I have replaced the:
fuel pump
engine harness
oxygen sensor
intake air temp. sensor
and motor,although it did this on the past two motors as well.

but i still get this cel when the engine is under load.I have no driveablility issues untill the light comes on.The car starts first try every try and the motor is very solid.I get average gas mileage,around 25-30 running premimum.

Please any help is very much appreciated!!!


Is there something i am missing that could be causing this code??

madsteez

any?

Gas cap seal? I don't know about Hondas, but some cars will throw a code for a bad gas cap. Good luck.

Have you looked at the troubleshooting instructions in a factory manual???

Replace your O2 sensor and check the wiring to make sure the insulating coating wasnt stripped off any. That happened to me.

Its a new harness and new 02 sensor.

Does it come on after you have been driving for a little while?

fuck im an idiot. My bad for not reading the first post entirely.

Try a fuel pressure regulator. Unless you have swapped that out with the swaps.

check your crank angle sensor or check your dizzy my car had the same problem

Only if its under load,like putting it in 5th gear at say 25mph,and trying to punch it to get up to speed.


It did this on the last motor,which was an entirely different dizzy.
