What does is mean when you do a scan and the brake light and ABS light keeps blinking?

Question

I did a scan on my dodge caravan and the brake and abs light where blinking and the 2 codes that came up where PO442 and PO455. Can someone help me out

Answer 1

That's normal. the brake and ABS light blinks. The code you have P0442 is for EVAP system small  leak detected , P0455 is for the EVAP large leak detected.  what the EVAP system does is prevents raw fuel from evaporating into the atmosphere, In order to set a large leak detected and a small leak detected. is the leak detection pump does not turn on, and it is usually do to a vacuum hose connection, these vacuum hose on the leak detection pump tends to degrade or collapse when the engine vacuum is applied.
