Is Your Saturn ION Acting Up? Get a Reliable Fix, Fast.
If you’re dealing with a frustrating no-start condition, erratic engine behavior, or a persistent Check Engine Light on your 2005 or 2006 Saturn ION, a failing Powertrain Control Module (PCM) is a very likely culprit. I’ve seen it countless times in the shop: a great car sidelined by a faulty computer. This isn’t just an inconvenience; it’s a problem that affects your car’s performance, fuel economy, and reliability. Instead of facing a costly and time-consuming trip to the dealership, we offer a straightforward, dependable solution.
This is a genuine, used OEM Powertrain Control Module (part number 12599726) carefully sourced from a salvaged vehicle. The real value, however, is in our professional programming service. Before this PCM ever leaves our facility, we flash it with the latest official GM software updates, precisely matched to your vehicle’s unique Vehicle Identification Number (VIN). This means it arrives at your door ready for a simple, plug-and-play installation.

Expert Pro Tip: Check This Before You Swap
In my 20+ years of diagnostics, I’ve seen many PCMs get replaced unnecessarily. On these IONs, a common point of failure is the main engine-to-chassis ground strap. It’s a braided cable, often near the engine mount, that can corrode and cause all sorts of electrical gremlins that mimic a bad PCMโlike flickering lights and intermittent stalling. Before installing your new module, take 10 minutes to locate that ground strap. Ensure it’s clean, tight, and free of corrosion at both ends. A little preventative maintenance can save you a huge headache.
Plug-and-Play Installation: No Dealer Visit Required
You can perform this replacement yourself with basic hand tools. Our pre-programming service eliminates the need for expensive scan tools or a trip to the dealership for flashing.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10 minutes for the system to fully discharge.
- Locate the PCM: On the Saturn ION, the PCM is typically located in the engine bay, near the firewall or air filter housing.
- Disconnect Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed PCM in the same location, ensuring it’s secure.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new PCM until they click into place. Reconnect your negative battery terminal.
- Perform Security Relearn (If Needed): In some cases, a simple security relearn procedure may be required. This typically involves turning the key to the ‘ON’ position for 10-15 minutes. Your vehicle’s manual will have specific instructions.
