That code has to do with a leak in the (EXuast) System, Or a (Defective) Upstream or Downstream (Oxagen) Sensor.

P0442 = Evap Control System

This means that the computer has noticed a leak in the Evaproative Emission System on your vehicle.
The most common cause is a loose gas cap.

Other causes could be a leak somewhere in the hoses and valves that connect the various parts of the EVAP system.

Many shops track down the leak be putting smoke into the EVAP System and locating where the smoke comes out, thus finding the leak.

P0455 and p0442


p0455-- emission control system ( a large leak ) the most common cause is a bad seal on fuel cap, remove and replace cap, if light stats on. replace cap. if not the cap it could be any where in emission system. p0442 is--same as above. Code p0442 indicates a fuel vapor leak in the EVAP control system. To fix this problem, remove and reinstall the gas cap. Clear the codes and drive to see if the codes reappear. If the code appears again replace the gas cap or inspect the system for cuts or holes in the tube or hose. good-day !
