P0442-EVAP LEAK MONITOR MEDIUM (0.040) LEAK DETECTED What you can do is go to Advance Auto Parts, or Auto Zone, and have them reset it, and it may go away. Sometimes it will come on when the gas cap is loose. You can tighten your cap, and unhook the negative battery cable for 10 min, that will reset it too. If it comes back, then you have a leak in your emissions system, but unlikely. A medium leak is something you would notice in performance. Thanks.

It means you have a leak in the EVAP system. Most likely the hoses near the charcoal canister. Check the EVAP hoses for cracks, and replace as necessary.

My 2004 dodge neon had it's check engine light come on the codes that came up are P442 and P456 what do they stand for?


they are for evaperative emmisions leaks.usually its a loose gas cap that causes these codes they are small leak codes.check gas cap, give it a couple of turns more to be sure its tight.
the car has to make 3 consecutive trips that detect no leaks before light will turn off.each trip has to start with a cold engine gas level between 15% to 85% of full.
or clear codes with code reader and drive car as usuall. if a leak is detected twice then the light will come on again.if it does then you will need to look for cracked vapor hoses,leaking canister etc

Engine maintainance light on

if its a service light you need not worry too much but you can also get the service reset tool on line

What does code 1-p0650 mean?


P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction

Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.

Possible Causes:
  • Harness or connectors (MIL circuit is open or shorted.)
  • MIL bulb may be faulty
