Dodge Neon PCM, ECM, ECU & TCM for Sale

VIN-Programmed Dodge Neon PCM, ECM and TCM Modules

Car Computer Exchange supplies remanufactured, VIN-programmed engine and transmission computers for the Dodge Neon. A Dodge Neon PCM is the engine computer, and PCM, ECM, and ECU all name that same unit; the TCM is the separate module that runs the automatic transmission.

Every unit ships with the latest factory Dodge software loaded and matched to your VIN, then tested for compatibility with your specific car. The Neon modules are plug and play: the computer is pre-programmed to your vehicle, so it needs no bench programming or flashing from you before you install it.

Each Neon computer is a remanufactured unit that is rebuilt and tested before it ships, not an untested salvage part, so it is ready to install when it reaches you.

Common Dodge Neon PCM Failure Symptoms

A failing Dodge Neon PCM usually shows up as a starting or running problem, because the module controls fuel delivery, ignition timing, and emissions. Common signs include:

• No-start, or the engine cranks with no ignition or injector pulse
• Rough idle, misfires, or hesitation under throttle
• Poor fuel economy or a failed emissions test
• Erratic, delayed, or no shifting on automatic cars
• Check engine light, a stored P0601 internal memory fault, or a "No Bus" message on the dash from lost communication with the module

On immobilizer-equipped Neons, a used computer from another car can let the engine start, run for a second or two, then stall, because it is matched to a different vehicle and its keys. A module programmed to your own VIN is the correct replacement, though immobilizer-equipped Neons may still need a security relearn to pair it. Every Neon engine computer we ship runs through a 13-point test on a computer-aided vehicle simulator that checks it against your car and VIN.

Dodge Neon PCM vs TCM: Which Module You Need

Match the module to the failure. The PCM is the engine computer, so no-start, stalling, and running faults trace back to it. The TCM is a separate computer that manages the automatic transmission, so shifting problems usually point to the TCM instead.

Car Computer Exchange stocks engine computers for every Dodge Neon model year from 1996 through 2005, and transmission control modules for 1996 through 2003. Order by your exact year: for example, the 2002 Dodge Neon PCM, the 2000 Dodge Neon PCM, or the 2002 Dodge Neon TCM. The Neon shares its platform with the Plymouth Neon, so Plymouth modules follow the same process.

FAQs

Do I need a dealer to program a replacement Dodge Neon PCM?

The module itself does not need dealer programming. Every Dodge Neon PCM from Car Computer Exchange ships pre-programmed to your VIN with the latest factory software, so it installs plug and play. On Neons with the Sentry Key immobilizer, the security system may still need a relearn to pair the module to your keys, so check your year's requirements before installing.

How do I know if my Dodge Neon PCM is bad?

A bad PCM usually causes a no-start, stalling, rough idle, misfires, or erratic shifting, often with a check engine light. Confirm it with a scan tool: an internal-memory trouble code or a loss of communication with the module points to the PCM. Rule out the battery, grounds, and wiring first, since those cause similar symptoms.

Can I just swap in a used Dodge Neon PCM?

A used PCM is matched to the vehicle it came out of, and on immobilizer-equipped Neons it is tied to that car's keys. Installed as-is, it can cause a no-start or a start-and-stall. A module programmed to your own VIN, not pulled from another car, is the correct replacement. On immobilizer-equipped Neons you may still need to relearn the security system to your keys.

Will a Dodge Neon run without a working PCM?

No. The PCM controls fuel delivery, ignition timing, and emissions, so the engine cannot start or run without a working one. A Neon with a failed PCM needs a working replacement programmed to the vehicle.

Is the Neon ECM the same as the PCM?

Yes. On the Dodge Neon, ECM, ECU, and PCM all name the same engine control computer. The automatic transmission is run by a separate module, the TCM.

What years of Dodge Neon do you cover?

Car Computer Exchange stocks engine computers for the Dodge Neon from 1996 through 2005, and transmission control modules from 1996 through 2003. Order by your exact model year so the module matches your vehicle.
