I really need to take a couple weeks off to get educated...I had no idea all this changed with FAST XFI:
What the heck does this mean!?! "Programmed sensor bias voltage out of tolerance"
27.3.3 Fault CodesTo determine what fault code(s) have been set, observe the “Error Code” and “ErrorCode 2” channels. They will display a numeric code which can be used to look up what fault has occurred. The possible faults are listed here.
Error Code 1:
1: CTS Fault
2: ATS Fault
4: MAP Fault
8: TPS Fault
16: Wideband Fault
32: Ign. Voltage Fault
64: Overboost Fault
128: IAC Fault
Error Code 2:
1: CTS Bias Error
2: ATS Bias Error
4:
Fuel Composition Sensor Fault 8:
Injector Duty Cycle Fault 16:
Fuel Pressure Sensor Fault (AAUX1) 32:
Oil Pressure Sensor Fault (AAUX2) 64: Cam Sync Position Error
128: Crank Sync Position Error
If the “Error Code” channel has a value of 4, it means a MAP Fault has occurred. Or if “ErrorCode 2” has a value of 64, a Cam Sync Position Error has occurred. If more than a single fault code has been set, the value of the error code channels will be the sum of the individual fault code numbers. When this happens, there is a simple way to determine which faults have occurred. Determine the largest single fault code that fits into the displayed error code number. That will be one of the fault codes that have been set. Subtract that number and again look for the largest single fault code that fits into the remaining error code number.
For example, assume “Error Code” = 37. 37 does not match up with any single fault code. The largest single fault code that fits into 37 would be 32. So 32 would be the first fault code. 37-32 leaves 5. Again, 5 does not does not match up with any single fault code. In this case, the largest single fault code that fits into 5 would be 4. So 4 would be the second fault code. 5-4 leaves 1. 1 does match up with a single fault code, so it is the third fault code. So in this example, there has been an Ign. Voltage fault, a MAP fault and a CTS fault.
Error Code Definitions:CTS FaultCoolant temperature sensor measurement approaching or at range limit
[size=0pt]
If a CTS fault code is set, the ECU takes the following actions to protect the engine.[/size]
- Fan output is switched on
- Target idle speed is forced to 1000 RPM
- EGR function disabled
- CTS based fuel correction zeroed out
ATS FaultAir temperature sensor measurement approaching or at range limit
[size=0pt]
If an ATS fault code is set, the ECU takes the following actions to protect the engine.[/size]
- In Speed Density mode, fueling calculations performed based on an air temperature of 59 *F
- EGR function disabled
- ATS based fuel correction zeroed out
- ATS based spark timing correction zeroed out

for my order to arrive. I thought I remember reading that people have sprayed their compressor clutch with WD40 to loosen it up. Before I go out there and start spraying WD40 everywhere...i
