Is Your Buick Rendezvous Running Rough?
If your 2002 or 2003 Buick Rendezvous is experiencing frustrating issues like a persistent check engine light, erratic shifting, poor fuel economy, or even a no-start condition, the problem may lie with a failing Powertrain Control Module (PCM). As the central computer for your vehicle’s engine and transmission, a faulty PCM can cause a cascade of performance problems that can be difficult to diagnose. Don’t let a bad module keep you off the road. This direct-fit replacement PCM is the reliable solution to restore your vehicle’s performance and drivability.
From the Diagnostic Bay
We had a 2002 Buick Rendezvous come into the shop with a classic complaint: intermittent stalling at stoplights and a check engine light that kept coming back for a random misfire. The owner had already replaced the spark plugs, wires, and even an ignition coil, but the problem persisted. After hooking up our professional scan tool, we noticed the live data for the fuel trims was completely erratic. Instead of chasing more sensors, we went straight to the source. A failing driver circuit inside the original PCM was causing the inconsistent injector pulses. Installing a correctly programmed replacement module solved the issue on the first try, saving the customer from further expensive and unnecessary part replacements.
Symptoms of a Failing 2002-2003 Rendezvous PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Failure to pass state emissions testing.

Frequently Asked Questions
Do I need to get this PCM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install with the latest GM software for your specific vehicle.
Where is the PCM located on my 2002-2003 Buick Rendezvous?
On the Buick Rendezvous and most other compatible models listed, the Powertrain Control Module is located in the engine compartment on the left-hand (driver’s) side, typically housed within the air cleaner assembly.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM, then yes, this replacement part will resolve the issue. It’s crucial to have your vehicle properly diagnosed to confirm the PCM is the root cause of the fault codes.
Is any special procedure needed after installation?
In some cases, a security relearn procedure (often called Passlock or VATS) may be required for the vehicle to start. This is a simple procedure that can typically be done without special tools and involves a sequence of key turns. A Crankshaft Variation Relearn (CASE) may also be needed with a scan tool to ensure optimal engine performance.
