Is Your GM Vehicle Running Rough?
If you’re dealing with frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a no-start condition, the problem might be your vehicle’s brain: the Powertrain Control Module (PCM). For many owners of late-90s GM vehicles, including the Chevrolet Cavalier, S10, Malibu, and Pontiac Sunfire, a failing PCM can be the root cause of a wide range of mysterious electronic and performance problems. This replacement Powertrain Control Module, part number 8162280160, is the definitive solution to restore your vehicle’s reliability and performance.
From the Diagnostic Bay
I once had a 1998 S10 pickup in the shop that was driving its owner crazy. It would start and run fine for a week, then suddenly refuse to start for two days. No rhyme or reason. The owner had replaced the battery, alternator, and fuel pump. We checked for spark and fuel pressure, and everything seemed intermittent. After hours of chasing wires, we hooked up a high-level scan tool and noticed the PCM would randomly stop communicating. We swapped in a known-good, programmed module, and the truck fired up instantly and never had the problem again. A faulty PCM can create ghost-like issues that are impossible to pin down without addressing the core component.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various codes
- ✔ Engine stalling or shutting off while driving
- ✔ No-start or hard-start conditions
- ✔ Poor engine performance and hesitation
- ✔ Decreased fuel efficiency
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to communicate with diagnostic scan tools

Frequently Asked Questions
How do I provide my VIN number?
After placing your order, you can send us your 17-digit VIN through the messaging system or include it in the notes section during checkout. We cannot ship the module until we have your VIN to program it.
Is this part difficult to install?
The physical installation is typically straightforward. It involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and installing the new one. The most important step is ensuring the battery is disconnected before you begin.
Will I need to do anything after installing the PCM?
In many cases, you may need to perform a security relearn procedure (also known as a Passlock or VATS relearn). This procedure syncs the new PCM with your vehicle’s anti-theft system and can usually be done without any special tools. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this cycle three times. Instructions are widely available online for your specific model.
What if my original part number is slightly different?
This module is a direct replacement for service numbers 16228016, 8162280160, and 16245305. As long as your original module carries one of these numbers, this part will be a compatible replacement once programmed to your VIN.
Do I need to send my old PCM back?
No core charge or return is required for this part. You can keep or recycle your old module.
