Code p0442 refers to evaporative emission system(EVAP)--small leak detected==causes-- hose connections,--intake leak--EVAP canister--EVAP canister purge valve
it also refers to large leak detected ( loose fuel cap/missing cap) causes--mechanical fault--hose connections---EVAP pressure sensor
If it has just started then check that the fuel cap is on tight or replace the pressure sensor or lastly ( it will probably the most expensive) the purge valve.

This could be a small evaporative system leak. Check the gas cap to be installed fully. If fully installed may need replaced.

Engine Code 301


Code # 301??? That is NOT a valid Diagnostic Test Code (DTC) for the engine control system on a 2000 Mercury Sable.

Assuming that you mean P0301, that is a cylinder misfire code that is identifying number 3 cylinder as the cylinder with the misfire problem. MANY things can cause a cylinder to misfire including spark plugs, spark plug wires or boots, burnt valves, broken valve springs, blow head gaskets, cracked cylinder heads, bad or dirty injectors, faulty injector control circuits, Failed ignition coils...the list goes on....proper diagnosis required.

Service engine soon light came on


The reason the "Check Engine" light comes on is because one of the sensors attached to your vehicle's engine is throwing a signal to the car's computer saying that there is a problem. The problem can be found by plugging into the car's diagnostic port and finding the error code, then fixing the problem. There's one problem with the old "plug a paperclip into the diagnostic port and read codes" trick-it only works on pre-1995 cars, which use OBD1 systems. Cars 1995 to present are OBD2, which require that you use a code scanner. You can purchase a code scanner at just about any car parts store, which can be rather costly and is recommended to be left to having a qualified tech do a computer scan.
I know this tool is helpful for your car.

2001 Sable gets P0401 first, then gets P0442 some miles later. When P0442 sets, so does engine check light. Car runs well. What could cause this sequence of error codes?


This could be a small evaporative system leak. Check the gas cap to be installed fully. If fully installed may need replaced.

Barring any vacuum leaks, P0401 is indicative of a bad EGR valve. Hope this answers your question. Best of luck.
