Toyota Avalon - Popular Questions, Answers, Tips & Manuals
2005 Toyota Avalon with codes p0441,p0455,p0456,p0505 and the vcs abs and traction light on?
You have a few different things coming up as these lights and codes. I'll list the code meaning below.
Did you mean the VSC light? VSC, Traction Control and ABS all refer to your braking system so get it fixed AS SOON AS POSSIBLE!
The '505' code refers to the air flow management system in the air intake manifold. The other codes refer to the EVAP system on the vehicle. This may seem a silly suggestion but check you fuel filler cap isn't loose, missing or the seal on the cap isn't damaged. The EVAP works as an air tight system and if it is leaking that is one of the most common causes, (and its a cheap repair).
P0441 = Evaporative Emission System Incorrect Purge Flow
P0455 = Evaporative Emission System Leak Detected (large leak)
P0456 = Evaporative Emission System Leak Detected (very small leak)
P0505 = Idle Air Control System
