Hi guys, I'm new to the forum, but have been using it since i bought my car for tips and ideas.
Not too long ago, I came across an issue on the motorway, where i went into "PGM-FI" mode (limp) in 6th gear cruising at 120km.
I analysed the issue and found the code (P1065) popping up.
After clearing it, I drove it and everything was fine except once i pass 120km somewhat harshly accelerating. The same issue arises.
So after research, the first thing i done was replace the fuel filter, I installed an OEM honda denso fuel filter and the issue was fixed for perhaps 6-7 hours.
Then it came back.
I was confused, and began to research more, I saw various answers to my issue such as , "a worn fuel pump, fuel pressure sensor and perhaps a new fuel rail.
As two of the three options are quite expensive,
I didn't see it being plausible as the car drives perfect, starts like a charm and no weird noises cranks what so ever. But suspiciously, once i pass 120-140km. I go into limp mode.
So today, i found out that, this limp mode and error code only pops up when i some what harshly accelerate past 120km. (Half pedal down), but if i accelerate slowly past this point. I don't get this issue.
So in conclusion, i only go into limp mode and receive the error code (P1065) "low fuel rail pressure" when i accelerate harshly at 120km.
I'm worrying that this could be signs of a worn fuel pump but I was wondering If anyone would have any opinions on this confusing situation before i get it diagnosed or buy a new fuel sensor for it not being the cause
Thank you very much in advance
