Is Your Oldsmobile Silhouette Experiencing Frustrating Engine Problems?
If your 2001 or 2002 Oldsmobile Silhouette is suddenly stalling, refusing to start, shifting erratically, or has a check engine light that just won’t go away, the problem often points directly to a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, when the PCM starts to fail, it can cause a cascade of confusing and seemingly unrelated issues. In my 20+ years of diagnostics, I’ve seen these GM modules cause headaches for countless owners and technicians alike.
Recognizing the Symptoms of a Failing GM PCM
A faulty PCM doesn’t always fail completely at once. It often starts with intermittent problems that can be maddening to diagnose. You might be dealing with one or more of the following:
- โ No-Start or Hard Starting: The engine cranks but won’t fire up, or takes an excessively long time to start.
- โ Engine Stalling: The vehicle dies unexpectedly while driving or idling at a stoplight.
- โ Erratic Transmission Shifting: Harsh shifts, delayed engagement, or getting stuck in one gear (limp mode).
- โ Check Engine Light with Communication Codes: You may see codes like U0100 (Lost Communication With ECM/PCM) or other errors that point to a module failure.
- โ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- โ Reduced Engine Power: The vehicle feels sluggish and lacks its usual acceleration.
Expert Pro Tip: Check Your Grounds First!
Before you condemn the PCM, do yourself a favor and check the main engine and body ground connections. On these GM platforms, a corroded or loose ground wire can mimic PCM failure perfectly. I’ve seen many vehicles come into the shop with a ‘bad PCM’ diagnosis that were fixed with a $2 bolt and a wire brush. Specifically, check the ground strap from the engine block to the chassis and the main ground point near the battery. A simple check with a multimeter for voltage drop can save you a lot of time and money.
