Blinking Cruise Control Light and sollid Check engine light
I have a 2008 Subaru Outback Wagon 2.5i and the cruise control mantle light is blinking and the check engine light is on sold. The gage put it on the computer and it reset itself. The code was listed with issues with the gas cap. We replaced the gas cap and make sure it is on tight but after 4 days the lights started again.
So what was the code? I am just guessing here....P0442 SUBARU - Evaporative Emission Control System Malfunction... Possible causes - Missing or loose fuel cap - Incorrect fuel filler cap used - Fuel filler cap remains open or fails to close - Foreign matter caught in fuel filler cap - EVAP canister or fuel tank leaks - EVAP system hose leaking - Fuel tank leaking... The P0442 code means that the control module has detected a small leak in the Evaporative Emission (EVAP). Loose fuel tank filler cap is the most common cause that triggers the P0442 code......P0445 SUBARU - Evaporative Emission Control System Purge Control Valve Circuit Shorted... Possible causes - Faulty Evaporative Emission (EVAP) Purge Solenoid Control - Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted - Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection.
The most common code in this Subie iteration is PO420: cat conv insufficiency. SOA will reflash ECM, and if unsuccessful, may replace front cat assy under extended recall. If not it's financially prudent to ignore it, asa cheaper aftermarket cats do NOT work. Second most common I see are misfire codes (PO301-4) from an ignition wire that's wet or dressed too closely to the intake manifold ground field. Oily plugs from seepage through the valve cover gaskets can be a culprit. (Note that your OE NGK plats are infamous for losing their anodes, so be just jump up to any decent iridium to outlast your car.) So as Ro said: what's the code?
SubaruGuruBoston...I have the code in the car I will check and message back later. All information is very helpful.
