Check Engine Light On/ Emission Control ??


Recommended Posts

Posted

Anybody out there in Legacy land possibly help me out ?

 

My 2004 Legacy Wagon SE had the fuel system cleaned. The next day, the Check Engine light came on. I had it scanned by the garage who performed the cleaning, and all they could do was relay to me the error, which read something like "Emission Threshold met, error # ????"

 

It is not the cat converter, as there is no loss of power, maybe an oxygen sensor perhaps ?? Any information would be appreciated.

Did you get a code? It may help a bit more.

 

And actually - cleaning the fuel system may cause small debris to actually clog injectors or so. Really hard to tell without seeing the code and make a closer inspection.

 

Just check that all hoses and connectors are connected - it's easy to forget one.
