- When Monitored: With the engine running, vehicle speed between 32 and 88 kph (20 and 55 mph), throttle open for a minimum of 120 seconds, ECT greater than 70° C (158° F), Catalytic Converter Temperature greater than 600° C (1112° F) and EVAP Purge active
- Set Condition: The PCM detects that the oxygen sensor signal switches from lean to rich less than 16 times within 20 seconds during monitoring. Two Trip Fault. Three good trips to turn off the MIL.

1/2 OXYGEN SENSOR <<< most likely cause
if you're going to replace a downstream O2 sensor, best to replace the upstream one as well.
an aging upstream sensor combined with a new downstream sensor can cause catalyst efficiency codes.
i wish they never would have taken away the vehicle profile from post headers.
That's awesome Pete thank you so much for the great info, I will buy a round in March when we see you in California.

ok just bought a 06 charger srt 8 after driving it for a bit the check engine light is now on has a rough idle and is throwing codes p0308, p2323, p2308 and says cats are below threshold. The guy I bought the car from says it has a cam but didnt know what kind and wihtout a tuner. It has magnaflow exhaust and a cai. I need ideas on what to check. I have already changed plugs and am changing coil packs tomorrow. How can I check to see if the PCM is bad?
- When Monitored: Any time the engine is running and the adaptive numerator has been successfully updated.
- Set Condition: If the Powertrain Control Module (PCM) detects that the variation in crankshaft speed between each cylinder exceeds a calibrated value, based on engine rpm and load, a fault is set.

ok tried new coils same problem the shop said that sometimes computer said that injectors 1,3,5 were bad. they checked them and said they are pulsing fine. IS there a way to check my computer to see if its bad?

not the same coil pack. i just combined the 2 diagnostic charts because the tests are identical (except for the circuit identifications).
K18 > coil 3
K98 > coil 8
edited my last post to reflect this.
got a bit of a problem over here!
started up my maggi yesterday. and drowe to work, suddenly the check engine light and abs/bas light and the traction light popped upp.... HUmmm..
well got to work and read the codes and this is what i got..
c2100 battery level to low,
c2116 abs pump to low voltage.
i still have the original battery so went and bought a new battery hooked it up and delited the codes. but after 5-6 min the same codes still appears!!!
and i also noticed that all of tha ligths i the cluster were pulsating! so did the front lights!
so now my toughts go to the altenator...
anyone got any idea?
^^ definitely get the charging system tested and check battery, pass-through, IPM, starter and alternator connections as well as grounds.
well done and checked.. changed the battery now(again!). and someone mentioned to me that the voltage ragulator is in the enginge managment unit, and that ill have to get an new one.(a new engine manageent unit! sounds expensive!.. so my question is... does any one know where ill find a dealer? tryed to scan online but whitout any luck.....
im driving modball europe this summer so it would be nice to have everything in order berfor that
P0308...i know it's an eighth cylinder misfire, but it came on before and went away for months, but recently has stayed on for the last week or so. any ideas for fixes? plugs maybe? anything i can do myself?
Hey there, love the info provided, got a possibly strange code, cant find it anywhere, google is even letting me down. First a little background, heading home from work today, glanced down at the speedo and there was nothing, under 0. Needle not moving at all. I trouble shot as best I could with no tools, no loose circuit breakers or anything and with a couple starts and shutdowns it wiggled but still stayed below 0 once. So I decided to drive it home, made the trip fine but through various speeds possibly including up to 100kph no movement whatsoever. Reading here on the forums found the method to get in the cluster diagnostic mode and tried it. It spat out 4-04 which I assume is the software version and an h1910. I cant find h1910 anywhere, except apparently hp is making some tablet or something with that model number.
I would really appreciate some more knowledge, Im guessing its the gauge itself since I tested the cruise control and seemed to be holding nicely, though Im not sure what it takes its reading from. I can only assume there is a transmitter and the speedo and cruise controls are the receivers. Thanks alot in advance.
the only codes you can retrieve through the cluster are PCM codes. H1910 is not a valid code.
is the speedo needle on the correct side of the stop post?
Yesterday I got a CEL for W0025? Said left bank voltage high. I reset it to see if it will come back but I can't find any info on "W" codes? Thanks!
