Thread: 1993 Saturn SL1 'service engine soon' light

    Default 1993 Saturn SL1 'service engine soon' light

    My '93 SL1 with 143k miles suddenly had the SES light come on a couple
    days ago. The light only comes on going 65 mph or greater on an upward
    incline, or at 68-70 mph minimum on flat ground. Any idea what this
    could be? It recently barely failed an emissions test, but I didn't
    drive it much before the test.

    Since I started a new job right down the street, I've very rarely
    driven the car at highway speeds in the last 6 months.

    I've been reading posts about how to acquire the trouble code, and
    haven't had a chance to look at the car yet, but might as well ask now
    if the connector that needs to be jumped is merely under the dashboard,
    or is it inside the dashboard?

    Actually to amend my first post - I used a paperclip to get the fault
    code (this is all new to me), there is only one: 26 "quad driver output
    fault"

    It appears it could be the following: EGR solenoid (no EGR fault 32
    though), evap canister purge solenoid, coolant fan relay, A/C relay,
    speedometer output, coolant hot light, and traction control in '93
    automatic model.

    The compressor on this car has been dead since I bought it, and it
    never sent out any faults before. As far as I know, the coolant fan is
    functional as of last week, but better check again. The engine was
    running cool when this occurred. Canister purge solenoid, whatever
    that does, is suspect...guess for a $15 part it's worth replacing.
    Sounds like it craps out on tons of Saturns in this year range.

    This seems likely. My wife's car had similar symptoms (SES came on
    while driving at medium to high speeds, Code 26) and it was the
    canister purge solenoid. It's a bit of a pain to get to but if you get
    under the car and use a mirror to look at the back of the engine it's
    not so bad.

    Could also be the EGR valve solenoid.

    Well, my SES light came on in my 97 SC1 and I was also experiencing a
    rough idle. Had fuel pump replaced ($450) - light goes off. Few weeks
    later, comes on again! Now I have to get something called an ignition
    module replaced($330). They say it will fix the rough idle (dealer
    mind you, yeah I know I know) and it does NOT. I don't know what else
    to do. IT is also going close to overheating in traffic as well which
    Im told is OK as long as it doesn't go into the red. Are these guys
    rooking me or what? So, Im concerned about the rough idle. Any ideas?

    How did you use a paperclip to get the SES code?

    How many miles... When was your last tune up... What is the condition of
    your plugs and wires... Did you go to long before a tune up... What are
    your plugs gapped to... and What are the codes?

    "My Saturns over heating" is all we hear on here every summer. The gage
    is missleading, 2/3rds is nothing. When your engine reaches 220 degrees
    your fan will kick on.

    112000 and YES, I also had a tune up which I prob didn't need because I
    had one a year ago. Ive spent 1500 in the last month and I'm about to
    pull my hair out!

    Get the engine code. My guess given the lack of any other information and
    with the 112K mileage (later message) stated is the EGR valve. I'd also
    suggest a good cleaning of the throttle body to address the rough idle if
    the engine was recently tuned.

    AutoZone stores will read the codes for free...others may as well.
