    My 2001 Silhouette has nearly 100K miles and recently the "service traction system" message appeared as did the ABS and "trac off" lights. My local mechanic cleared the ABS history code 1218 pump motor short but the problem reappeared. Anybody experience a similar issue? Also, the fuel gage is bouncing all over the place and I noted an earlier post suggesting a possible fuel level sending unit. Doesn't qualify for "cash for clunkers" but perhaps it's time... Thanks.
  • I have a DTC P0301 w/pending code P0405. Old. Silhouette. 2000
    model year. 3.4l E engine. Approx 140,000 mi. I have a series of
    questions related to this vehicle. With in previous 6 mos., 25 total
    miles added to distance traveled, and approx. 20 hrs. of engine time
    elapsed it has been through the ringer. Great looking inside and out.
    comfy and pleasant to operate. Just can't quite get it smoothed out.
    Several hours of actual troubleshooting invested. New lower intake
    man. gasket, new after market (not original equip.) fuel pump and fuel
    quantity sending unit, coolant flush, 2 oil changes, Lucas brand fuel
    system cleaner added to fuel, New OEM leads and plugs, New after
    market coil pack for 1 & 4 cylinder, air filter, thermostat, vacuum
    lines and fittings, used fuel pres. reg., used MAF sns., used TP sns.
    All installed used parts ops checked good. Pulse light check on
    injectors seemed good. What should be done from here?

    Check wiring to the EGR value and if that is ok change the EGR value.

    Have received an estimate to address the "service traction system" and ABS and "trac off" lights. Need to replace ABS modular assembly and traction control pump for approx. $4K. Don't think the car is worth that much. Any ideas or suggestions? Thanks.
  • Thanks for the direction. Checked the wiring to EGR valve. ops checked good. Swapped EGR with operational valve and the problem duplicated. I no longer get DTC p0405. I do still have a p0301. Replaced power circuit ground cables and ohm checked the grounds to PCM. All checked good.I replaced the air filter again with different manufacturer. Cleaned the MAF sensor. Seemed to have accumulated more glaze than normal over short period of time. I replaced the fuel pressure sensor when the fuel pump was replaced. I used the original seal for the pump. I had difficulties installing the seal that was provided with new pump. Currently I have oil at the throttle body valve and noticed oil at the vent tube that crosses over the rear of engine that vents the valve covers. Although the exhaust is visibly normal in color and doesn't smell of burning oil. Also the pcv was installed when I did the intake manifold, and has a good "rattle" to it. The one thing I have not checked is converter failure. I also had a little bit more of a resistance on the EVAP purge valve control. I suppose I could also have a faulty fuel injector at the #1 location due to current misfire. Any additional feed back is well appreciated.

    Swap the injector with another one. If the misfire moves then that injector is bad. The problem with the oil could be a back pressure problem and could be the cat converter.
  • Hi. So I replaced the #1 fuel injector. Did not solve the problem. Still getting DTC P0301. I did take a compression test and results were as follows: #1 cylinder 20lbs, #2 cylinder 135lbs, #3 cylinder 151lbs, #4 cylinder 150lbs, #5 cylinder 150lbs, #6 cylinder 145lbs.

    Knowing that the #1 cylinder was low when conventional compression test was administered I proceeded with a differential compression test. I set the piston to TDC on the compression stroke and regulated 90 psi into the cylinder. The cylinder held every bit of 90 psi. I rotated the crank to achieve TDC of the exhaust stroke and again regulated 90 psi into the cylinder. And again the cylinder held all of 90 psi.

    Back to the conventional method. The very first time I cranked the engine and started building pressure the gauge barely flickered. Then I ran through the procedures again. 20 psi. On the third consecutive test on the #1 cylinder it held pressure. All the way to 120 psi. So I tested it again. 20 psi. And again 20 psi. I did this 6 times consecutively and got the same, 20 psi. On the 9Th try the cylinder held 120 psi. Any thoughts would be greatly appreciated.

    1998 OLds Silhouette 110,000 miles
    For the 2nd year in a row the A/C has failed.
    Last year a recharge lasted more than 2 months ....
    this year the recharge lasted about 5-6 weeks...
    Same shop decided this year the problem was a 'core' leak...
    cost to repair $1000 ????
    What are the most common A/C issues with Silhouette ???
    I figured a line leak going to the rear unit?
    Core leak seemed a stretch as it wasn't 'found' last year.
    Am I just being paranoid... :surprise:
  • A good friend has a '99 Olds Silhouette van. He has had it for about 5 years and it has been relatively trouble free, although he did replace the transmission about 2 years ago. He says it has been one of the best vehicles his family ever had, and he says he gets respectable gas mileage from it. He was here today and we changed the oil. He told me that the service engine light was on for the last few days but when he got here this morning, it had gone out. Nevertheless, I scanned the van with my OBD2 and got a code PO101. The book says this about it-"Mass or Volume Circuit Range Performance Problem". Could someone please translate the meaning of this code for me and perhaps suggest a course of repair action, if one is called for? Thanks a bunch.
  • HAVE 2000 SILHOLOET 3.4 V6 188000 MILES REBUILT MOTOR 30000 MILES AGO YESTERDAY STARTED MAKING TAPING SOUNDS FROM THE LIFTERS I EVEN HEAR A KNOCK HEAR AND THEIR IS THEIR ANY THING THAT CAN CAUSE THIS OTHER THAN A BAD OIL PUMP WITCH WAS REPLACED WITH A HIGH FLOW PUMP WHEN I REBUILT THE MOTOR WOULD THE KNOCK SENCER MAKE THE LIFTERS RATTLE IF IT IS BAD

    The rubber elbow on the PCV is cracked on my 99. I temporarily taped it up and is working. I could not find just that piece and bought the complete tubing. This elbow and tubing is one piece. While going to replace it, it seems it goes to the far other end of the manifold in the back. Will I need to roll the engine forward to access that end or can I get it through the back on a lift?
  • YES IT IS POSSABLE FOR YOUR CAR TO BE OUT OF ALLINMENT AND YOU NOT KNOW I HAVE AN OLDS ALERO,
    ONE OF THE BACK A FRAME IS BENT AND IT GOSE THREW A TIRE EVERY SIX MONTHS AS SOON AS I FIX THE PROBLEM WITH MY NOISEY LIFTER ON MY VAN I AM PLANNING ON REPLACEING THAT AND GET A FOUR WHEEL ALLINMENT JOB DONE.
    THE CAR HANDLES FINE IT JUST GOSE THREW A LOT OF TIRES
  • CHECK THE POWER STEERING PUMP MINE MAKES THE SAME NOISE ONE MINUTE WHINNES LIKE CRAZY THE NEXT NOTHING IT HAS BEN DOING IT FOR THE LAST YEAR AND A HALF ONCE IN A WHILE I PUT SEALER IN IT STOPS FOR A WHILE I FIGURE AS LONG AS IT WORKS I WILL LEAVE WELL ENOUGH A LONE
  • I THINK MAYBE YOU GOT A BAD ONE.
    I HAVE HAD MINE FOR FIVE YEARS NEVER HAD A PROBLEM UNTILL A YEAR AGO AT ONE HUNDRED AND FIFTY SIX THOUSAND MILES IT BLEW UP SO I REBUILT THE MOTER I AM HAVE A FEW ISUES LATELY BUT I WOULD BUY ANOTHER ONE I A MINUTE
  • A BAD FULE INJECTORE BUT YOU MIGHT WANT TO LET THE DEALER DO I JUST DID ONE AND IT IS A JOB YOU DO NOT WANT TO DO
  • I have a 2000 Oldsmobile Silhouette with 255000 miles on it. Recently, the Check Engine Light came on, then off. I have it check anyway. The Code Reader shows Trouble Code P072 - Torque Converter Circuit Stuck On. Can anybody tell me what it is? And what need to be done to fix it? Thanks. :confuse:">

    The rear window washer is not putting out any fluid. Is there a seperate pump from the front? The front works fine. If not I would suspect a loose/broken hose somewhere.
  • azuazu Posts: 84
    I am going to answer my own post.

    There are two pumps in the reservoir, one for front and one for back. I found my problem, it was a disconnected line just before the firewall. I love easy fixes!!

    I have a 99 and wonder if there is anyway to drain any moisture accumulation in the compressor and/or shock. Since it has been below freezing I am getting a knocking noise from the rear suspension, like that of a bad shock, for about 5-30 minutes depending on the temp. I suspect that the shock has frozen water in it.

    To replace this do you need to roll the engine forward or can you access the back of the intake manifold up on a lift?
