Ok, so, got my SCT Tuner in the mail today from Brenspeed, and I've used it to check out these codes that (I'm assuming) are from the O/R Prochamber that I'm running. The codes that I come up with are 2195, and 2197. A search on the great Google led me to this.

P2195 02 Sensor Signal Stuck Lean (Bank 1 Sensor 1)
P2197 02 Sensor Signal Stuck Lean (Bank 2 Sensor 1)

Can anyone confirm this for me, and that these are the rear O2 sensors that I'm lookin for? And, if that's the case, can someone tell me exactly what I need to do to turn those off using the tuner? I tried lookin for it, but didn't see it, and I'm a lil hesitant to just start trying things, haha.

I'll list obd sources as i find them.....this list does not
show your codes...

interesting, this list doesn't show it either....

Here's the problem....that sheet only goes through 0800....which is standard transmission codes.....I'm gettin 2195, which I'm fairly sure is a Ford, and maybe even Mustang specific code. Thanks for tryin, though.


<edit> Heh, you edited as I posted, thanks for the help.

Are they solid codes?
IOW if you clear them do they come back?

undecided.steve

Sorry, I missed the part where you say you don't know how to clear them
I don't either since I don't have my SCT yet.

So, after some kind soul tells you how to clear them do they come back and is the MIL light on?

I don't have an SCT tuner, however "Sensor 1" indicates the front sensors, this is from the '03 factory manual--P2197 is the same thing for the other bank (driver's sideIIRC)[/align][/align]



P2195 - Lack of HO2S-11 Switch, Sensor Indicates Lean
A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

[*]Electrical:
[*]Short to VPWR in harness or HO2S[*]Water in harness connector[*]Open/Shorted HO2S circuit[*]Corrosion or poor mating terminals and wiring[*]Damaged HO2S[*]Damaged PCM [/ul][*]Fuel System:
[*]Excessive fuel pressure[*]Leaking/contaminated fuel injectors[*]Leaking fuel pressure regulator[*]Low fuel pressure or running out of fuel[*]Vapor recovery system [/ul][*]Induction System:
[*]Air leaks after the MAF[*]Vacuum Leaks[*]PCV system[*]Improperly seated engine oil dipstick [/ul][*]EGR System:
[*]Leaking gasket[*]Stuck EGR valve[*]Leaking diaphragm or EVR [/ul][*]Base Engine:
[*]Oil overfill[*]Cam timing[*]Cylinder compression[*]Exhaust leaks before or near the HO2S(s) [/ul][/ul][/align]

Alrighty....the thing is, I haven't noticed anything different about the way the car drives.....I think I'm fairly in tune with my car, and I hadn't noticed anything but the improvement in performance. Yes, the codes stick, I've cleared them twice now and they come back after I've driven for a while. If anyone has any idea what this could be, I appreciate the help.

At the risk of sounding facetious, I'd start by checking the things listed in the factory troubleshooting chart I posted...

Heh, guess that'd be a good place to start, eh? Just wondering if there were any common problems that would make this codes pop up.
