Check engine light on. P0325, P0420 2000 Subaru

Have the codes read. Check the brake fluid level. Wouldn't surprise me if low brake fluid doesn't kill the engine know days.

did you check the oil leavel? if so and the oil leavel is good it
could be the oil pump.

First thing to do is have the computer scanned for trouble codes.

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.

try replacing the gas cap, u may have a leaking pressure relief valve in the cap, this can turn on the check engine light as it is sensing a fuel vapor leak.

There is a tube that connects to the EGR valve that gets blocked up-take it off and clean it out

try disconnecting the + positive terminal for a few minutes and see if it goes out most likely the 02 sensor needs replacing ...however low fluid levels may also contribute to this oil,brake fluid etc.

Take to autoparts store and have them run the diagnostics, then if still a problem, report back.

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.
