'95 Saturn SC2 with codes 19, 26 and 32

Bill 13 February 2005 00:11:13
 Hello all,

My daughter just dropped off her '95 SC2 for me to fix up and I have a
couple of questions. I flashed the codes and got 19, 26 & 32. From what
info I've found in past posts, 26 & 32 are probably both pointing to
the problems in my EGR or Canister solinoids. I'm about to go check
that.

I have found no useful information on code 19, though. Does anyone have
any pointers? I haven't driven the car enough to verify everything, but
over all it seems to run okay.

Thanks for your Help!

Bill

Code 19= "6x signal fault" The 6x signal is sent from the CPS
(crankshaft position sensor) and used by the PCM and DIS
(distributorless igniton module) to set ignition timing. An intermittant
6x signal fault is generally caused by loose or back wiring or connector
at the CPS or a CPS on it's way out. (About a $15 part)

 I checked my CPS. It was on the high end of the spec, to I replaced it
and inspected all wiring. Still, after about 15 seconds of running,
code 19 comes back and the SES light comes on. The engine runs fine.

I also have an extra PCM which I have used as a test. It logs 19 also.
Any suggestions?

The other two codes also keep recurring. I suspect the purge control
solinoid is the culprit for the 26 code. All hoses, wiring etc. look
good.

This car will not pass state inspection with the SES on and stored
Emmisons codes.

 I seem to recall 19 was the purge solenoid. However, it turned out to be a
cracked vacuum hose at the rear of the engine (twin cam) and not the valve
itself. I couldn't get to it as it was a hoist job.
The 32 is probably the EGR valve which you may be able to clean and degunk.
Dunno about the 26 though.

 Update: On the code 19, I finally found the culprit. The 6x ref. wire
(or something like that) coming from the coilless ignition system (CIS)
and going to the PCM was bad. I replaced the wire and the code went
away. Unfortunately, so did my tach. This is the part that doesn't make
sense to me. I hooked the original 6x ref. wire to the new wire at the
CIS, no code and the tach works. The original wire must be bad before
the tach signal wire breakout.

The code 26 is still a problem. I ordered a new Canister Purge Solinoid
today and will get it tomorrow. Seems like all this is taking forever,
but I only have short periods of time to work on it.

Thanks for all the free advise. Maybe the above will help someone else
sometime. BTW, the Hayes manual is wrong about the Tach wire and the
DIS.
