Help! What do all these trouble codes mean?
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
|
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. |
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-ass 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? |
i think he got it from my thread :)
|
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 |
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? |

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 |
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.
|
But how can I get an unlisted code? P0100 has to stand for something.
|
Although there were some changes in the 04/05 model yr CEL table..
P0100 is not listed on either. :confused: |
P0100 is listed generically on the internet as an air flow circuit issue. Is your idle very lumpy?
|
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.
|
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.
|
noticed any oil dripping? maybe they didnt replace the crush washer? check the airbox for oil there also.
|
The strange thing is that I havent noticed any oil dripping at all. I'll check the airbox today.

Here is a screen shot of what I am talking about... This is my CANScan unit interface screen.
|
Can the CANScan determine flash level?
I see you started a new thread ref oil usage? |
No, sadly not. The Canscan can not determine flashlevel.
|
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.
|
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?
|
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.

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

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 :) |
