P0455 - DIY?


Recommended Posts

Hi All,

I'm backkkkkk...

I got the CEL on, 2 weeks ago. :soapbox:

Autozone called it the P0455 (Large leak on the EVAC). Looked up the Bentley - says the same thing.

The guy at Autozone asked me to try on a different gas cap and turned off the light.

Came back on today again... :censored:

There were two threads here on this code in this forum but there were other ones along with this p-code in these threads.

I'm only having this code from the OBD...

Any ideas on how to get rid of this? Is this a DIY? :wrench:

Should I take it in to my local indie mechanic - reliable chap though...

The car is a 2000 S with 63.5K on the odo. Completed the 60K service at 57.5 though... :king:

Could a possible leak off the radiator (I saw some fluid drip off the radiator on the driver's end - from the front - a while ago) trigger this p-code? :oops:

Appreciate your valuable inputs (as always :))

Vish :drive:

Loren - you rock!

Now that I have a new gas cap there - that should eliminate the first two items ?

I will look up the layout for the Ventilation lines health-check from the other items from Bentley - but any pointers off the block on what to look up. All these ventilation lines being detached - is that a plug and play i.e. if something is disconnected (due to jolts/mishandling), should I just put it back in place?

Here is one more fact on the car - on 12/30/06, I got rear-ended - bumped basically at a stop light, which led to a fix-up-paint rear bumper job.

Could this have triggered off any of the ventilation lines issues? I didn't have the CEL on before this incident.

Thanks again for your promptness.

Vish
