You need to replace your idle air controller (IAC). IAC basically opens and closes the throttle at idle so it stays at constants RPM.  Hope this helps.  Thanks for an honest rating and for using FixYa.

Vdc and check engine light on no traction in snow or rain 2004 subaru outback h6


Even with the VDC light on it shouldn't fishtail. Unless you have a lead foot or the tires are bald. Best to have the codes read. Could just be a bad wheel sensor.

05 outback p2009 code and cruise control light flashing


Hello,

I am unable to find a P2009 code. The closest I have come across is a P2109 which is:

THROTTLE/PEDAL POSITION SENSOR "A" MINIMUM STOP PERFORMANCE

Which will usually be accompanied by:
  • Improper idling.
  • Poor driving performance.
  • Engine stalls.
Also the "Cruise" light will always flash when the Check Engine light is on with these later models, but it does not mean there is a concern with the Cruise control. The diagnostic checks for these cars require the SDS: Subaru Diagnostics System.(A laptop computer with Subaru specific diagnostic software). These concerns are unfortunately not easy to diagnose w/out Subaru dealership resources. I hope this info helps.

There could be a hundred causes for a check engine light. First step is to hook up a computer scan tool and see what codes the computer has. The next step depends on the codes.

How do you reset engine check light on 2004 Subaru Outback?


u can clear/reset the check engine light either with a scan tool, hit clear codes, or u can just disconnect the battery, the scanner clearing method is preferred as disconnecting the battery can cause temporary stalling issues.

2003 Subaru Outback check engine light stays on


You may have to take it to a shop and have them connect their OBD tool to the computer and clear the deep memory. If you have a code left in the deep memory it can reapear like that. Good luck. Please rate me so I know how I'm doing. Thanks.
