Restore Peak Performance to Your Vehicle
If you’re grappling with frustrating engine problems like a persistent Check Engine Light, erratic idling, stalling, or poor fuel economy, a failing Powertrain Control Module (PCM) is often the culprit. As the central computer for your engine and transmission, the PCM is critical for managing everything from fuel injection and ignition timing to emissions controls and shift points. When it begins to fail, the symptoms can be widespread and difficult to diagnose. This replacement module, part number 16228016, is the definitive solution for a wide range of late-90s GM vehicles, including the Isuzu Hombre, Chevy S10, Cavalier, and Pontiac Sunfire.
From the Diagnostic Bay
We once had a Chevy S10 with the 2.2L engine in the shop that was driving its owner crazy. He had replaced the spark plugs, wires, ignition coil, and even the EGR valve trying to chase down an intermittent misfire and stalling issue. The codes were all over the place. After confirming all the new parts were working, we hooked up a scope to the injector drivers at the PCM. Sure enough, the signal for cylinder 3 would drop out randomly. The root cause wasn’t a bad sensor or wire; it was a failing driver inside the original module. A correctly programmed replacement PCM solved a problem that had cost the owner hundreds in unnecessary parts.
Is Your Powertrain Control Module Failing?
A faulty PCM can manifest in numerous ways, often mimicking other component failures. Before you continue replacing sensors and other parts, check if your vehicle is exhibiting these common signs of a bad engine computer:
- ✔ Illuminated Check Engine Light: The most common symptom, often with codes that are inconsistent or point to multiple sensor failures.
- ✔ Engine Stalling or Misfiring: The engine may stall for no reason, run rough, or experience random misfires.
- ✔ No-Start Condition: The engine cranks but refuses to start due to a lack of fuel or spark command from the PCM.
- ✔ Poor Fuel Economy: Incorrect fuel mixture and timing calculations can cause a sudden drop in your MPG.
- ✔ Failed Emissions Test: The PCM directly controls the emissions systems, and a failure will almost certainly cause you to fail a smog check.
- ✔ Harsh or Erratic Shifting: In vehicles with electronically controlled transmissions, the PCM also manages shift logic, and a failure can lead to poor transmission performance.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is a powerful computer that acts as the ‘brain’ of your vehicle’s engine. It takes data from dozens of sensors to control fuel injection, ignition timing, emissions systems, and automatic transmission shifting to ensure optimal performance, fuel efficiency, and low emissions.
Do I need to do anything after installing this module?
Because we program the module to your VIN, it is typically a plug-and-play installation. However, on some GM vehicles, a security relearn procedure (often called a Passlock or VATS relearn) may be required. This is a simple procedure that can be done without special tools and typically involves a sequence of key turns. Instructions are widely available online for specific models.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on the vehicle itself. Look for a small metal plate on the driver’s side of the dashboard visible through the windshield, or on the sticker inside the driver’s side door jamb.
How do I know for sure that my PCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis is best. This involves checking for consistent power and ground at the PCM connector and testing sensor inputs and outputs. If multiple, unrelated sensor codes are present or if a diagnostic scan tool cannot communicate with the module, it’s highly likely the PCM is at fault.
What happens if I don’t provide my VIN?
We cannot ship your part without a VIN. The programming process is essential for the module to function correctly in your specific vehicle. An unprogrammed module will not start the car or will cause significant performance and compatibility problems. Please provide your VIN promptly after ordering to avoid delays.
