Oldsmobile Intrigue Problem Codes/TSBs



  • Secondary Air Injection System what is this and where is this. Please Help!!!

  • This relates to the air pump that works when engine is cold to help reduce pollutants. Search the set of Intrigue forums for air pump and you'll find plenty of messages. I got mine replaced in my 2001 GLS last July... about $400 at the dealer. My brother's 1999 GLS had similar issues.
  • Now I get the code P110 I wonder if the one code P110 is causing the other P410

    HI , I have a 2001 trigue, and drove by to Autozone and they hooked up the computer for free diagnostic.....mine came up with 2 codes, po-118 engine coolant temperature circuit hi input, and po-171 system too lean, bank 1?

    My car does not overheat, and if the second code for lean mixture requires a oxygen sensor, where the heck is it? I got under the car today, and could not find it. Any help is greatly appreciated!!!! still trying to find a manual that covers everything!!!!!! Issy

    P0118 could be as simple as a bad thermostat.

    For P0171, check out Post number 477 in the "Oldsmobile Intrigue problems & solutions -Read ONly" forum.

    The Secondary Air System is an air pump and check valve located behind the drivers side headlight. Just pull up two plastic locks and the whole headlight assembly will come right out and you will see the Secondary Air Pump. This air pump is used to pump air into the exhaust manifold for a minute or so during start up to burn some of the excess hydrocarbons for a little emission control. It has no effect on the smooth running of the engine. The 1998 model did not even have a air pump. It was added to the later models to aid in passing the emission tests. No use wasting money on a fix. Just ignore it if you can. Now, how do I tell the computer to ignore it and turn off the SES light?
  • dtownfbdtownfb Posts: 2,915
    Unfortunately ignoring the problem isn't an option in some states. If the SES or "Check Engine" lights are on, in some states, they will not even perform the inspection until it is fixed since it likely has to do with emissions control. Best bet is check websites like or for discounted parts and get a friendly mechanic to install it for you. Or try a salvage yard.
  • When I check my manual for code 1676 it states: ODMD Output 6 Circuit Faulty. Can anyone tell me exactly what that actually means and where to look for the problem.

    The solenoid on top of the charcoal canister needs to be replaced.
  • 01 Intrigue has engine code P1258. Just had smog test done and failed with faulty gas cap. Replaced today. Can't find any more info on remaining engine code problem.

    According to my info P1258 is an overheating condition. It says the PCM starts shutting down cylinders in order to cool the engine. Does it run poorly? Is the temp gauge about where it normally is? Mine rarely goes above the 1/2 mark. If everything seems normal, disconnect the negative bat. terminal for a few minutes and reconect it again. This should clear the code, at least temporarily. If the temp. gauge is reading high, you have a cooling system that needs help.

    The service engine soon light recently lit up my dash. The troubleshooting code came back at P0420 "Catalyst efficiency low bank 1. Anyone have experience with this code? Any ideas on how to resolve this problem?
  • indrgbindrgb Posts: 115
    Has anyone had a problem with your dash lighting up like a Christmas Tree? Sometimes, usually after it's warmed up, the following lights stay on after starting it up: ABS, Service Vehicle Soon, Trac Off, BRAKE, PCS. I had a mechanic scan it when the lights were not on, and he said the only thing in the history was C0550, which is an electronic brake control module (EBCM) malfunction. He thinks this module is failing. Has anyone had one of these replaced? I know it will be expensive. The mechanic guessed about $600.

  • dtownfbdtownfb Posts: 2,915
    Before he replaces the EBCM, have him check the wheel hub assembly. The ABS sensors are on the wheel hub assembly and sometimes the sensors fail causing those lights to come on. Unfortunatley, you have to buy the entire wheel assembly. They can be salty. Normally only the ABS, Service Engine soon, Trac Off lights come on with a bad wheel sensor. So your mechanic could be right but the wheel sensor is a very common repair on the Intrigue.

    Thanks for your reply. I took it to the mechanic again today while the warning lights were ON. He scanned it and said it had the same code, C0550, EBCM malfunction. He said if the wheel speed sensor had a problem it would show up on his scanner. I called a dealer and they wanted $1014 for the part. After regaining consciousness, I told him never mind. I called a small independent parts shop and they said they could get the same dealer part for $715. I checked GM parts direct and it was $643. I'm not done yet. I still think I can find it cheaper. BTW, the p/n the dealer gave me is 88894772.

    This DTC identifies a malfunction within the EBCM. (electronic brake control module )

    Conditions for Running the DTC
    The ignition switch is in the ON position.

    Conditions for Setting the DTC
    DTC C0550 is set when an internal EBCM malfunction exists.

    Action Taken When the DTC Sets
    If equipped, the following actions occur:

    * The EBCM disables the ABS/TCS/VSES and MSVA for the duration of the ignition cycle.
    * A malfunction DTC will set.
    * The ABS indicator turns on.
    * The TCS indicator turns on.
    * The PCS indicator turns on.
    * The Red BRAKE Warning indicator turns on.

    Conditions for Clearing the DTC

    * The condition for the DTC is no longer present (the DTC is not current) and you used the scan tool Clear DTC function.
    * The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

    Had your mechanic tried clearing/reset the codes with his scanner? 'Cause a100 drive cycles may take a couple months depending on driving habits.

    I would for the fun of it, disconnect the battery and unplug then replug the connector going into the EBCM and then reconnect the batt.

    EBCM is under the hood right of the master cylinder in front of the box with all the brake lines.

    Thanks Moonshadow. I think I will disconnect the battery. Right now I'm a little worried that replacing this module won't cure the problem, and them I'm out $700. My mechanic has a nice Snap-on scanner, but he said it won't do everything that the dealer scanner will do. He said it might be worth spending $100 at the dealer so they could do a functional test of the EBCM. If the problem continues, I might do that. I will still come out ahead since I'm saving $300 on the part.

    Update on EBCM. I did some research and found a place that will rebuild the brake module for $200. I shipped it today. The company is called Modulemaster. They also sell them on ebay. The feedback is all positive. Their warranty is 5 years. I'll post again after I get it back and try it out. If it works, it will be a $1000 savings compared to the dealer part and labor.

    Last update on Brake Module (I hope). I receicved the brake module back from ModuleMaster on Monday. So far everything is working normal again. All warning lights are out. They gave me a sheet of what was repaired. The main problem was "no communication". This module was a Bosch 5.3. If it fails again, I'll post back, but I think this was the right move. $200 plus shipping. This was a huge savings. I removed it and installed it myself. A little tough, but not too bad. I would like to see more places like this. Not good for the dealer parts business however.
