egr solenoid

When applying +12v to this solenoid, with wiring harness
disconnected, should it just make a barely audible click noise
that indicates it's working? Still trying to get to the bottom
of a code 26. Hoping it isn't the purge canister solenoid which
is harder to fix.

 

put my money on purge canister solenoid, mine was giving error codes ,
checked the resistance it was border line, Strange thing is the ones at
saturn dealership were border line also, took my tester and checked for
the best one they had, its been ok since !

 

What was the resistance reading with the ones Saturn had, and
also, what was the reading value of the one you accepted? Just
curious as to what to expect should I need one.

Actually, the code 26 may, in my cars' case, might have been set
by a faulty turn signal/4-way flasher module. Awhile back, I
noticed that both the 4-ways & the turn signals would 'freeze'
at times so I did get one flasher replacement module today for
$10.00, popped it in, and so far - no more code 26. I'll check
it again every couple days to insure it's OK. Somewhere, someone
on the WWW either commented that the code 26 could be caused by
a blown dash light & that can set this error code. So, thinking
that the 4-ways & turn signals, getting frozen, might trigger
the code, I gave it a shot. Will see.... Sure don't want to do
any purge cannister solenoid during this time of year, here, if
it can be at all avoided.

 

I took my solenoid to service department and we checked the 4 or 5 that
they had all were about 22 ohms, mine was about 22 ohms and i belive it
was still working but the computer in the car was rejecting it, one that i
took may have been 22.5 ohms i took that one, the 91-93 repair manual i
have says they should be 22 to 42 ohm !

 

When applying +12v to this solenoid

I am not sure if this device is 12v or 5v.

I seem to recall my purge solenoid was acting up, too, some months ago. If
that is located on backside of the engine (between engine and firewall) on
the twin-cam. Seems the vacuum hose dried and split back there and that was
the problem. It was a bear to get to and needed a hoist to get it from
underneath (dealer did it as I gave up trying to do it from topside).
