Product Details

Cardone 77-0806F is a remanufactured PCM in the Powertrain Control Module product line, built for Saturn SL and Saturn SL1 vehicles that use OE part number 21020806. As the vehicle’s engine control computer, the PCM manages critical powertrain functions and must be programmed after installation. This unit requires vehicle-specific on-car programming after installation and vehicle-specific flash programming on the vehicle to help prevent drivability and starting issues. Search terms such as 1991 Saturn SL PCM replacement, 1991 Saturn SL1 powertrain control module, and Cardone 77-0806F OE 21020806 replacement all point to this application.

This part cross-references Saturn (e.g., 21020806) for the same application.

What This Part Helps Address

• Engine no-start conditions related to PCM failure
• Drivability problems caused by incorrect powertrain control signals
• Faults tied to a damaged or nonresponsive control module
• Issues after replacing an original Saturn SL or SL1 PCM
• Need for an OE-number-matched replacement module

Installation Notes and Tips

Fits 1991 Saturn SL, N/A. Fits 1991 Saturn SL1, N/A. On-car programming must be performed after installation, and flash programming is required on the vehicle. Verify OE number 21020806 and connector/terminal configuration before installation. Because this PCM is vehicle-programmed, proper setup is essential to avoid starting and drivability concerns.

Quality Assurance

This Cardone remanufactured PCM is built as an OE-style replacement for the listed Saturn applications and is supplied in a metal housing with the specified connector configuration. E-waste designation is marked Yes, reflecting the electronic nature of the component.
