Cardone 79-8455 Engine Control Module

Remanufactured ECM for Chrysler, Dodge, and Plymouth

Cardone 79-8455 is a remanufactured engine control module built for direct replacement in select 1991 Chrysler, Dodge, and Plymouth applications. It is pre-programmed at the factory for the listed vehicles and uses a 60-pin male connector with a rectangular plug layout for a precise OE-style match.

For 1991 Chrysler LeBaron, Dodge Daytona, Dodge Spirit, and Plymouth Acclaim applications, this ECM is a direct-fit electronic control solution that supports proper engine management and factory drivability.

Product Details

Cardone’s Engine Control Module line focuses on restoring OE-level operation through remanufacturing, inspection, and electronic testing. For this application, the module is rebuilt to address common failure points found in original units, including weak solder joints and damaged internal components. The result is a replacement ECM that supports factory vehicle communication and engine control on the listed Chrysler, Dodge, and Plymouth models.

This part cross-references Chrysler, Dodge, and Plymouth OE numbers such as 4720796 and 4723509 for the same application. Use Cardone 79-8455 when replacing the original ECM in a 1991 Chrysler LeBaron, 1991 Dodge Daytona, 1991 Dodge Spirit, or 1991 Plymouth Acclaim with California emission system coverage where specified.

What It Helps Fix

• No-start or hard-start conditions caused by a failed ECM
• Intermittent engine performance issues from internal module faults
• Driveability problems tied to corrupted or unstable control signals
• Electrical failures related to worn solder joints or damaged circuitry
• Replacement needs after diagnosing poor grounds, wiring, or relay-related control issues

Installation Notes and Tips

Before replacing the original ECM, verify the root cause of the failure. Check power feeds, grounds, wiring harness condition, and related solenoids or relays, since these issues can damage the replacement module if left unresolved. Confirm the OE engineering number on the original unit matches the Cardone cross-reference before installation.

For Chrysler PCM applications with a “V” suffix, VIN programming is required. Ford PATS and GM anti-theft reset procedures are application-specific and should be checked against the correct service information when relevant.

Quality Assurance

Each Cardone remanufactured control module is tested with automated computer equipment or bench-tested, depending on application, and validated on-vehicle for durability and performance. The remanufacturing process also reduces raw material and energy use compared with producing a new part, supporting a more resource-efficient repair.
