Question

I have the engine code P0135 on my 2005 Honda Civic EX 1.7L
Check Engine light on code says P0135 I checked the fuses all good, looked at the wiring looks good, I replaced the Bank 1 LAF sensor, clear the code check engine light goes off then comes right back on same code.
Any help would be great

Answer 1

If the light comes right back on this usually indicates a wiring issue. I would check for power and if there isn't any you need to check the wiring.

Answer 2
