Installed a catless DP, now have a CEL???

[polyarkos]

Hi guys and gals,

I\'ve just installed a Subtech 2.5" downpipe/front pipe on my BP5. Driving up to Hanmer I got a CEL but the car is running the same as before.

I\'ve replaced the 02 sensor as it was very very black. CEL went away for 15min but is now back.

I\'ve looked for the black and green connectors but cannot find them under the drivers dash.

How can I check and clear the CEL?

no black plugs on bp legacy\'s. green one located behind right hand kick penal and test mode connector located under lower portion of glove box

So just connect the plugs to get the CEL codes? How do I clear the codes? I\'m gonna let my car sit overnight with the -ve disconnected and see how that goes

under the glove box area there should be another set of plug (not sure of color) should be beside the green ones. connect it and turn ignition to on and than off after few seconds. disconnect and recheck again. that should clear the codes.

i have always used subaru select monitor so havent actually done this. this is what is written in the service manual so m just reading and relaying it to you.

dont think you can actually pull out code though because the engine code normally start with P on these newer models i.e P0031, P0036 etc etc.

if you are in auckland than pm me, i might be able to help you plug the scanner and retrieve the codes

Sorry, I\'m in CHCH. Thanks for the offer

Re-checked the DP today, turns out one of the studs that you mount the DP to the turbo has gone missing. I thought just the nut was missing but the stud has gone too.

Could an exhaust leak throw a CEL?

UPDATE: Checked CEL and came up with P0031 and P0037 (Thanks Scottiescottiescottie).

Since I have replaced the 02 sensor we cleared P0031 code, but still left with P0037

Upon further inspection I have also blown the SBF-5 fuse which will throw the above codes.

I\'ll replace the fuse in the morning and see if this clears the codes.

Did you find any frayed/damaged wiring on the old O2 sensor? Short Circuit will blow the fuse from what I can gather.
