Is Your Sunfire Running Rough? The PCM Might Be the Culprit.
If your 1997, 1998, or 1999 Pontiac Sunfire is suffering from perplexing issues like a persistent check engine light, erratic idling, stalling, poor fuel economy, or even a no-start condition, the root cause is often the vehicle’s central computer: the Powertrain Control Module (PCM). As the brain of your car’s engine and transmission, a failing PCM can create a cascade of problems that are difficult to diagnose. This replacement Powertrain Control Module, part number 8162280160, is the definitive solution to restore your vehicle’s performance and reliability.
This isn’t just a generic, off-the-shelf part. We take the guesswork out of the repair by programming each module specifically for your vehicle. After your purchase, you simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians then flash the unit with the latest, most stable factory software updates from General Motors. This ensures that the PCM is a perfect match for your car’s specific configuration, including its engine, transmission, and emissions equipment, providing a seamless and effective repair.
From the Diagnostic Bay
We had a 1998 Chevy S10 (which uses a very similar system to the Sunfire) come into the shop with a frustrating intermittent stalling problem. The owner had already replaced the fuel pump and a couple of sensors with no luck. The check engine light would come on and off, and a basic scan tool couldn’t establish a consistent connection. After verifying all the main power and ground connections to the computer were solid, we connected a professional diagnostic tool. We found that the PCM would randomly drop communication and lose its 5-volt reference signal to the sensors. This pointed directly to an internal failure in the module. We installed a VIN-programmed PCM, performed the security relearn, and the truck ran perfectly. It’s a classic example of how a failing computer can mimic other component failures, making a quality, correctly programmed module essential for an accurate fix.
Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling or cutting out unexpectedly while driving.
- ✔ Rough or erratic engine idle.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Scan tool cannot communicate with the vehicle’s computer.

Frequently Asked Questions
What exactly does a PCM do?
The Powertrain Control Module (PCM) is the primary computer in your vehicle. It controls all aspects of engine and transmission operation, including fuel mixture, spark timing, idle speed, emissions systems, and automatic gear shifting to ensure optimal performance and efficiency.
Do I need to have this module programmed?
No. The main benefit of our service is that we program the module for you before it ships. All you need to do is provide us with your vehicle’s VIN, and we handle the complex software flashing process.
Where is the PCM located on my 1997-1999 Sunfire?
On the Pontiac Sunfire and its sibling, the Chevrolet Cavalier, the PCM is typically located in the engine bay on the passenger side, mounted near the firewall or inner fender.
Is any other procedure required after installation?
Yes, in most cases you will need to perform a security relearn procedure, often called a GM Passlock Relearn. This syncs the new PCM with your vehicle’s anti-theft system. It’s a simple procedure that typically involves turning the key to the ‘ON’ position for 10-15 minutes, three times in a row. Instructions are readily available online.
How do I send you my VIN?
After you place your order, you will receive a confirmation email. Simply reply to that email with your 17-digit VIN, and our team will take care of the rest.
This part number is slightly different than mine, will it work?
This module is a direct replacement for several service numbers, including 16228016, 8162280160, and 16245305. As long as your original module carries one of these numbers, this part is a correct replacement once programmed to your VIN.
