93 SL1 - Purge canister solenoid?

Service light comes on intermittantly - generally only after the car has
got up to temp, and usually only when I slow down or come to a stop.
Scaned the PCM - codes 26, 32 came up.
I replaced the EGR solenoid and the PCV valve (EGR valve was done less
than 6 mo ago). Cleared the codes.....and guess what the service light
still flashes same as before.
This time its a straight code 26.
Anyone have any ideas? Please help
Some say that its the canister purge solenoid that probably the cause - I
have no idea where it is - how do I find it?
Is it as easy to do as the EGR solenoid?

Thanks,
Ian

 

Unfortunately no. The EGR valve and solenoid are in plain sight, and
trivial to change. The Purge Canister Solenoid is hard to get to. I had
to use a mirror to even see it. If you have small hands and your arm is
made of rubber, then you can get to it fairly easily. Otherwise, you have
to remove something (the starter?). Anyway, if you look just behind and
left of the EGR valve, then stick your had straight down and then to the
left behind the engine, you can grab it. Tell us if you get it done,
because I have a new canister solenoid that I've yet to install because
it's too damn hard, so any encouraging word will help me. Since the part
is so cheap, you might as well replace it.

Oh, forgot to mention that you need to remove the air intake hose to get
to it.

Ok I've looked and am I right in assuming I follow the vacuum tube round
the back and kind of under the throttle body and a bit to the left, where
it lies more or less on the engine block? If thats it - man its going to
be a pain.
I'll give it a try tomorrow.

Unfortunately the canister purge solenoid is not that easy to change. It is
similar if not the same as the EGR solenoid.

It is located on the side of the engine facing the firewall. It has two wires
going to it and a vacuum line. It is mostly replaced by "feel" from underneath
the car. The starter is blocking your view from seeing it easy.

OK I've done it!
I was a bit of a bitch - I went at it from the right side. I had to take
off the intake bracket, and pull off the fuel Hard lines (hence the EGR
valve) to get enough speace for my hand to fit. Well with some liquid
wrench, a 10mm rachet, a flashlight and a lot of cursing its off. Once
the bolt off the (2) vacuum hoses and the the wires have enought play in
them to pull the solenoid over enought to see what you're doing.
So I tested it and the resistance was 700+ ohms - so I have found my
culprit. I inspected the ends of my vacuum hoses and found the one
leading to the canister was ruptured - i guess the high heat area is
pretty hard on them - so I replaced that too......I haven't driven it yet
- so wish me luck.....I'll write a follow up in a few days.

Thanks everyone,
Ian

 

Ihad same problem, it was egr selonoid. very easy to replace, it is nears
the throtle body !

 

On my wife's 92 SL1 I got to it from underneath. I had to use a mirror
to see it at all, and after finding it it wasn't too bad to replace it.
