NEW CEL codes came up!!!! cant find what any of them are.
So i was T/S (trouble shooting) a rear O2 sensor problem for cel P0137 and flashed to GST 2.7 Pill+TBE 2010 ralliart usdm 93oct and drove around loging for about 20 mins no cel. parked then looks to see if i had any codes, check knock ect. I didnt have anything that looked bad and 0 knock. I figured i fixed the problem or it fixed itself. I decided its time for a stress test, put it in sport turned off ACS then turned logging back on in evoscan 2.9. i got to a light and a little civic wanted to play. I took off destroying that little fart can exhausted pos made it home then when i put the car into park the CEL came on. read the codes and got all of these.
P37E0 C1290
P20C1 P37A0
U0100 P1871
Noooooooooooooooooooooooooo!!!!!
Tried to look them up on the spot but didnt find anything. I reflashed back to the previous ROM GST pill+TBE 2.7 91oct cleared all codes then did another stress test then got home again held the brake put it into park..... no codes.
So in the mind set that i might aswell try to get a code so that i can help others in the future did some VERY agressive driving for about an hr on some back roads but not too far from home. still no codes. So what the hell just happened?
I think my car just "April fools"ed me. Oh you, silly Ancer you got me good.

U0100 Lost Communication With ECM/PCM
C1290 Pressure Transducer Circuit Failure
P1871 Mechanical Transfer Case 4×4 Switch Circuit Short To Battery

No one noted that he was using evoscan 2.9?
OP, evoscan 2.9 gives bogus codes. Use evoscan 2.8. Also, if you notice when you are looking for DTC's on evo scan check the EVO SST and the CAN OBD2 EDU's...they both have codes in those areas at times.
I have the same issues as well, im trying to fix. I disabled P0139 and P0140, but im still getting a CEL....need to do more research on my part it looks like.

crak is correct. Evoscan 2.9 came out with bugs in the multiple-CEL processing. It was apparently mixing bytes up, and feeding you bogus codes.
Check Evoscan site, etc. for updates.

PS. crak, gonna email you about your TBE related CEL.

I always clear codes after i flash. The codes have not come back at all so i think its good. I also always look in both EVO SST and the CAN OBD2 even EVO EFI

Do you have the vibrant 02 spacer? Coz both of us have UR DP but I'm using the UR HFc instead of TP. My issue is P0420 right now which is the catalytic code.

I was using it for a long time but it never helped no matter what spacer configuration so i turned off the cat codes via ECU. i just disabled the rear O2 sensor becuase i keep getting the O2 heater codes for the rear sensor, when there is a fix for it ill turn it back on. I already replaced the sensor but that didnt do anything but make me feel $140 poorer.
**update**
I dont remember exactly but it was something like set#2 bit 1 to disable the sensor

Right now, I'm experimenting using crak.
Wait, that came out wrong!
crak and I are working together to try out a few "disable" setting combinations. He's got a 2009 with TBE.
