Answer 1

P0455 EVAP system leak detected (large leak)

P0455 evap leak deals with the evaporative system where fuel fume instead of escapinging into the atmoshphere is captured into the charcoal canister where it is stored and sent to the intake where it is used. When you have a vehicle that does not go in reverse or foward, this is a transmission concern, Low transmission fluid will cause this, check the transmission fluid level when the vehicle is at operating temperature,
