View Full Version : Abbreviations on sensor check page on PFC Hand commander?


andyb1604-28-2013, 09:41 PMDoes anyone have a list of what the abbreviations mean on the sensor check screen on the hand commander? Specifically FPC, FPR, ELD, O2H, and FAN. A quick google identified ELD as something that is apparently only on Hondas.

Trying to figure out my random stalling issue and these are the ones my commander is showing lit up. If FPR is fuel pressure regulator, that would make sense, but the fpr is vacuum/boost/mechanically actuated not sensor driven right? So if it were malfunctioning, the ECU wouldn't be able to pinpoint it. Could it be fuel pump relay or something of that nature? CJMR2T04-28-2013, 11:13 PMELD is electrical load
FPC is fuel pump controls
FPR is fuel pump replay
O2H is o2 heater circuit (if memory serves me correctly)
FAN is fan switch
All of them are switched outputs except for the ELD which is a switched input. None of them are "sensors". andyb1604-29-2013, 01:11 PMSo what would them being lit up on the sensor check page mean? That they are working or not working the way they're supposed to? I'm clueless when it comes to this kind of thing. Powered by vBulletin® Version 4.2.5 Copyright © 2026 vBulletin Solutions Inc.
