I did some searching but did not find my answer.
I was driving home today and this little ricer started to mess with me, so I showed him how fast a 7500lb diesel truck was! Didn't take him long to realize he would not win.

After one good hard run I noticed the CEL came on. I returned to cruising speed until I could get off the freeway at my exit. Truck still runs fine. I even got on it a few short bursts with no problem. Will this code clear itself with a few key cycles?

Also my truck has no power mods so why would I even get this code? I have run it pretty hard several times with no issues.

P0192 Fuel Pressure Sensor Voltage Too Low

Could be that your stock lift pump is getting weak, and not providing full fuel pressure at WOT. Do you have a FP and RP gauge?

Unfortunately no gauges yet. I know I know

That would be the first order of business. It could be any number of things, from a bad connection, faulty sensor, failing batteries, or fuel pump. Gotta have more clues!

I wish I had more info.
If it was a quick drop in voltage to the sensor, will it clear itself or will I need to have the code cleared? Any ideas?

I guess I will be getting gauges sooner that I thought! And with money being an issue at times here, would a FP gauge be the first to buy versus the RP? Sine I do not suspect any issues at this time from the CP3.

madhat

It will clear after a certain number of key cycles. I don't know the exact number.

Thanks so far with the help Mark!

madhat

Anytime...

Looks like 5 key cycles and the light goes off
