SES light on again :(

Thought I had it nailed down but the SES lamp came on again today (2001
lw300). Same code - P0455 so the vent solenoid must be sticking open again.
Will order a new one since cleaning the old one didn't seem to be a long
term solution. At least this time, I won't spend 3 hours looking for the
location of the fool thing.

Picking up the new solenoid tomorrow. Will try CarQuest first. Most of the
independent shops in the area get their parts through them. I get the dealer
price so it is a good deal most of the time.

In the mean time, I started pulling fuses, one at a time, from the
under-hood fuse block. Found the one that resets the SES lamp and doesn't
affect anything else. Key off and pull the 'Control +' 10amp fuse for 30
seconds.

Last time I pulled the battery cable and wound up reprogramming the radio.
At least the anti-theft code wasn't set which would result in a lock-out.
(there is a way around that too if anybody is interested)

I really miss on my old Plymouth that you could just flip the key 3 times
without starting the engine, leave it in the on position and watch the check
engine lamp flash the codes. On the later ones with the electronic
instrument cluster, just hold down the odometer reset on key on to read the
codes in the odometer display. I haven't found a simple way yet on the
Saturn to read out the codes without a tool.

Don't you just LOVE OBDII? It's such an 'open' standard that you need a
speshul tool to read trouble codes, and it's hard to find info on the
system's internals, also....

Pre '96 saturns, you can read the codes with a paperclip. Very useful.

Just trying to find now if a basic tool that reads only the generic codes
will be enough or spend the extra money and get one that supports the
extended codes. I borrowed an OTC unit worth $2500 from a friendly repair
shop to run my diagnostics. He knows that I'm an engineer and joked that I'm
the only one he'll lend it to since I can fix it if anything happens to it.

Went to CarQuest today looking for the Canister Vent solenoid. "Not
available yet" I was told (for a '01 Lw300). Saturn parts ordered it for
about 20 bucks.
