@  borgwarrior : (15 December 2014 - 05:53 AM) Is there any chance of my car "forgetting" the auto lock, after I've changed the radio to another, which is still stock? (By auto lock I mean the central lock engaging over 20-is mph)

So what is it?

Did I do some additional damage to my a/c system?

Thanks.

Freeze Frame Data from my scanner:
Fuel Sys 1: CL
Fuel Sys 2: NA
Calc Load(%): 5.88
ECT(deg C): 73
MAP(kPa): 29.00
Engine RPM:1280
Veh Spd(km/h): 56

P.S: I already googled the code, so I'm looking for more than just the basics... does this have anything to do w/ the A/C system? Is it possible that with the heat generated from snapping the drive belt over the seized a/c clutch something else broke?

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Causes: A code p0455 most likely means one or more of the following has happened:

•A loose or improperly affixed gas cap
•A non-conforming gas cap (i.e. not factory/original brand)
•Other leak or damaged piece in EVAP system

Possible Solutions: With a p0455, the most common repair is to:

•Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
•Otherwise, replace the gas cap, and/or
•Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

Thank you Jess.

I already saw that...

Rather than just the definition of the code, I was more looking for an educated guess based on what just happened to the car's a/c system...

Car is running fine, although the CEL just appeared a few mins ago. A/C Clutch seized about two weeks ago. I was driving it for maybe a total of 10 miles while the light was on.

So looks like it was the gas cap, it was never screwed down... I put it back on and cleared the code.

I was worried that when the belt snapped it hit a hose or broke something under the hood, but maybe not.

Thanks!

That's great, glad to hear it was nothing bad and/or expensive.

I hate this code. i had this code so many times thats its not funny. here was my fix. the EGR tube that goes into the upper intake manifold was loose. there was a leak. if you have the car running and run your finger around there and you feel a little bit of suction. there it is. at school i did the smog test and thats how i found it. there are many ways. but dont replace parts when you dont need them. hope this kind of helps. hahaha. nothing to do with the Air Conditioning system. its an emission problem.

man i feel stupid. maybe i should read all the posts like 5 times before replying. i didnt even read that it was fixed. lol. WOOOOSH right over the head.
