P0507 Code - Idle Control System RPM Higher Than Expected

[arbies]

This morning when I drove to work, I knew something was a little off. I have the Phearable tune with pops, and normally when I put it into +R mode, I consistently get pops, but not this time. Also, when I was at a stop, the idle RPMs seemed higher than usual.

I plugged in the FlashPro and looked at the Hondata app and saw there was a P0507 code. I assume this code was preventing pops too.

Nothing has changed on the car in a long time. I have a Sprint air filter, TSP DP and tune.

After some Googling, it seems like I should check hose connections for leaks. Anyone run into this?

My son cleaned the MAF sensor, and that seemed to resolve the issue. No more code or high RPMs while idling, and pops are back now in +R mode. Thanks, @pigfacedalarm.

The issue came back, same code P0507. Used MAF sensor cleaner, and cleared code yesterday.

Now today it's throwing several codes:

• P0461 - fuel level sensor circuit range/performance
• P0300 - random/multiple cylinder misfire detected
• P0304 - cylinder 4 misfire detected
• P0301 - cylinder 1 misfire detected

Made an appointment at the dealership tomorrow morning.

Clear all codes through hondata and see what pops up. So only filter, downpipe and the reflash correct? Send me a log after you clear all the codes driving around to see if I see anything off.

I will try to figure this out for you!

Hi @Jester04. I didn't have time last night to gather logs and just dropped it off at the dealership this morning. I really appreciate you reaching out to help, though!

Any updates? Having same issue but this was after I did the prl charge pipes. Re-check and retightened my couplers and it would still occur because my pop/bangs would stop working. No cel but I can see it under hondata app. Gonna change intercooler gasket next to see if that fixes.

Triple check your work, any other mods?

Before cel, dp,ic,rv6 turbo, spoon exhaust, prl flex fuel e30, tune. After charge pipes, cel would trigger. Currently just did prl hvi too and still there. Clean maf sensor same thing. Just order new gasket for intercooler. Already change out map sensor to a new one too. Went I went back and recheck my work, took off the piping to tb and reinserted it. Same with the piping on turbo side. Only thing I can think off is the little hose and ic gaskets now.

Not losing boost or anything but it is annoying knowing when my pop/bang turns off due to this (pending) code. Also updated and reupload with fp current firmware.

Is the PRL flex fuel connected to the car to the ECT sensor?

No

No

Ok good don’t plug it in since it’s not supported for the FL5. I would recheck the gaskets for the intercooler.
