My car flooded (my fault) and it was towed in to the dealer (Oaktree Mazda on Stevens Creek in San Jose). They found a bunch of fault codes, but didn't explain them. I looked around both here and on the web for a list of codes and couldn't find it. Can anyone help?

The codes:

C2778
U1900
U0073 (EPS)
U1900 (EPS)
U1900 (IC)
U2516 (IC)
U1900 RKE
P2101 PCM
U0073 PCM
U0155 PCM
U2516 SASM


Thanks for any help you can give!

I hope you get a nice loaner/rental car

Mr M

Those trouble codes can all pop up if you have a flat battery. Basically, they are caused by communication failures with modules, because the modules don't have a sufficient power supply.
Don't worry about them.

JohnO

Whew! At first I thought that this enormous list was just MY codes...

The wrecker guy pissed me off! He INSISTED on leaving the key on and the window open a little all the way to the dealer (20 minutes). I'm sure the battery was low already after all the cranking I did to it. I wonder if I should go ahead and put in one of those Optima batteries.

I got a Mazda 3 base model with 20,000 miles and a weak-*** 4 banger. The front seat looked like someone had pee'd on it... I expected better from Hertz.

Thanks for the help! BTW Where did you get the list of codes?

zoom44

i think he got it from my thread

davefzr

Hey.. does anyone know what a P0100 means? I have the CANScan tool and the strange thing is that it says I have no pending trouble codes but then it lists P0100 and doesnt have a definition for it...

Anyone? THankx! I also have a CEL and fuel smell to go along with it..

life is grand haha

zoom44

since all of the first few p010x codes are for maf circuit trouble

P0101 MAF sensor circuit range/performance problem ON 2 CCM ´
(See DTC P0101 )
P0102 MAF sensor circuit low input ON 1 CCM ´ (See DTC P0102 )
P0103 MAF sensor circuit high input ON 1 CCM ´ (See DTC P0103 )

it's probably something wrong with your mafs. do you have an aftermarket intake?

zoom44

in the future you can just do a search for "cel codes" and you will find this thread in the results:

https://www.rx8club.com/showthread.p...ight=cel+codes

davefzr

Hey.. nah.. I have a stock intake.. I am going to take my car into the dealer tomorrow morning. Hopefully the problem will be fixed this time.

davefzr

But how can I get an unlisted code? P0100 has to stand for something.

snap-on

Although there were some changes in the 04/05 model yr CEL table..

P0100 is not listed on either.

sco

P0100 is listed generically on the internet as an air flow circuit issue. Is your idle very lumpy?

davefzr

Sometimes the rpm's will drop below 800 for a second and the car will catch itself and quickly bring the rpm's back up. This happens at idle yes... I am going to take my car in today.

davefzr

One other thing is that I got my 30k service about 1 month ago and 3 weeks later my oil light came on so I added 2 quarts of oil to fill it up. Today, a week or so later, I am back to the half way point. There is no way it should be consuming 2 quarts in a matter of weeks.

zoom44

noticed any oil dripping? maybe they didnt replace the crush washer? check the airbox for oil there also.

davefzr

The strange thing is that I havent noticed any oil dripping at all. I'll check the airbox today.

davefzr

Here is a screen shot of what I am talking about... This is my CANScan unit interface screen.

snap-on

Can the CANScan determine flash level?

I see you started a new thread ref oil usage?

foxy

No, sadly not. The Canscan can not determine flashlevel.

davefzr

Yeah.. well I didnt start the thread, just revived it from the dead. I am going to take my car into to the dealership this morning.

davefzr

Well.. I got my car back and the dealer said that because I used an aftermarket CANScan tool I am getting U error codes on the WDS tool. They also didnt find any of the P0100 or P0003 codes that are listed from my CANScan tool.. HUH? Anyone know what a U error code is?

zoom44

dave you have missing oil and a mafs circuit code. imy bet is the MAFS is fouled by your missing oil. get them to pop off the tube and mafs to have a look and clean it.

snap-on

https://www.rx8club.com/showpost.php...16&postcount=4

The U-codes pop up when there is a communcation issue between CAN modules..

davefzr

They told me they were caused because I used an outside tool that wasnt an ODBII approved method for access.. (An aftermarket POS basically)

This is our MAF sensor right?

I dont have the K&N.. just stole the pic. used it rather
