im gettin a few wierd codes when i scan now. just started gettin them. idk if ive always had them and if HP Tuners just started being able to read them(i think they are BCM codes), or if they are new. im gettin these codes:

C0237 - Rear Wheel Speed Signal Erratic (History)
C0240 - Unknown (History)
do these affect anything? and should i try to fix them?

also been gettin these, MAF is cause its not even connected for SD, and the TP sensor is something screwy sometimes, doesn't really seem to affect anything but turning off my TCS. doubt they are affecting the other 2 new ones, but figured it might help diagnose
P0103 - Mass Air Flow (MAF) Sensor Circuit High Frequency
P0121 - TP Sensor Circuit Insufficient Activity

 

anyone?

 

I'm getting the "C0240 - Unknown (History)" also after I installed my cam. Most of the other codes I had I got them tuned out. But I don't know about this one either.

As far as your Maf codes. I believe under Engine Diagnostics you can set the "MAF Fail High" to 0 Hz if you are runinng SD tune and Look at you Logs an see what your MAP kPa is at idle and set the "P021 Error Max Map" just above that.

Hope this helps. If I find what that other code is when talk to my tuner today I'll let you know.
