Dtcs Stored On My Truck

[joutlaw]

I'm getting a blackbearperformance data-logged tune and Justin found the following DTCs. They seems to relate with some of the issues I'm having with the truck.

 

CEL is on b/c of P0446.

 

ABS will kick in below 5mph on occasion. I get a nice warning chime on the highway sometimes when the ABS light illuminates.

 

HVAC works somewhat sporadically, but blows hot and cold. I figured the problem was the blower resistor, but now I'm not so sure.

 

 

Here are the codes... does anyone have any experience with them?

 

P0446 "Evaporative Emission (EVAP) Vent System Performance" MH ($10) "Powertrain Control Module (PCM)"

C0222 "Rear Antilock Brake System (ABS) Channel in Release Too Long" H ($29) "Electronic Brake Control Module (EBCM)"

C0223 "Left Front Antilock Brake System (ABS) Channel Motor Free Spins" H ($29) "Electronic Brake Control Module (EBCM)"

C0221 "Right Front Antilock Brake System (ABS) Channel in Release Too Long" H ($29) "Electronic Brake Control Module (EBCM)"

B1025 "Audio ([+] or generic) Output (1: left front or generic) Circuit(s)" HC ($80) "Radio (RAD)"

B0263 "Air Flow Control 6 (A/C) Circuit" H ($98) "HVAC Control Module"

B3770 "Air Flow Control 6 (A/C) Feedback Circuit" H ($98) "HVAC Control Module"

B0408 "Temperature Control {single or 1} (main or front) Circuit" H ($98) "HVAC Control Module"

B0414 "Temperature Control {single or 1} (main or front) Feedback Circuit Range/Performance" HC ($98) "HVAC Control Module"

I would try cleaning the ABS speed sensors on the wheels. And visually check the sensor itself. If they get dirty or corroded, you could get the problems you are seeing. Worse, the sensors are bad and will need to be replaced.

 

As for the EVAP I would try re-closing the gas cap and clear the code.

I'm getting Justin to remove all EVAP checks.

 

Could the HVAC codes be related to the blower resistor, or is this something completely different.
