Scooby snigs Posted November 27, 2017 Share Posted November 27, 2017 Hi could anyone advise. I have recently had the aa out to my imprezza 2.0l sport 1999 due to "check engine" light flickering .the aa chap said it was recording intake air temp sensor fault , I have changed the sensor for a s/h one but the "check engine" light is still coming on intermittently. Don't want to pay dealer price for a brand new sensor if it could be a wiring breaking down .anyone help?please Quote Link to comment Share on other sites More sharing options...

Scooby snigs Posted November 29, 2017 Author Share Posted November 29, 2017 Tried to reset ecu but would.nt clear .was advised to disconnect Battery overnight then reconnect and see if fault appears again . They seemed to think that ecu was really flagging old faults . Hope that makes sense?. Quote Link to comment Share on other sites More sharing options...
Greenmamba Posted November 29, 2017 Share Posted November 29, 2017 You only need to disconnect Battery for 30 minutes or so. Press the brake pedal a couple of times during that time, then reconnect Battery. All relevant codes should be cleared. Quote Link to comment Share on other sites More sharing options...
Scooby snigs Posted December 29, 2017 Author Share Posted December 29, 2017 Hi I have had problems with intake air temp senser which I have replaced but still keep getting check engine light flashing on , not as regular and goes off within 10 second , I disconnected Battery to reset ecu. Could air filter cause this problem ? Quote Link to comment Share on other sites More sharing options...

Tidgy Posted January 3, 2018 Share Posted January 3, 2018 sounds like there might be something else going on Quote Link to comment Share on other sites More sharing options...
Mr B Posted January 3, 2018 Share Posted January 3, 2018 Sounds like misfire warning to me as repeat issue would have the money light on always, check ignition leads, plugs and coil pack and replace leads/plugs if old or suspect issue found . knock sensor is another one for intermittent blinking money light on subarus .
