2000 Chrysler Sebring PCM/ECM Replacement and Programming Guide
The PCM (Powertrain Control Module) or ECM (Engine Control Module) in your 2000 Chrysler Sebring manages engine and transmission operation. Failure can cause drivability issues, no-start conditions, and stored trouble codes like P0601, indicating internal module faults.
Quick Summary
- The 2000 Chrysler Sebring uses either a PCM (Coupe) or ECM (Convertible) with different book labor times for replacement.
- Factory replacement requires a DRBIII scan tool for flash programming recovery per TSB 18-037-05.
- Book time for PCM/ECM R&R is 0.6 hours (Coupe PCM), 0.7 hours (Coupe ECM), or 0.4 hours (Convertible).
- A 0.5-hour relearn procedure is necessary after installing a new module.
- Trouble code P0601 is documented for this vehicle and indicates an internal control module fault.
If your 2000 Chrysler Sebring is experiencing drivability problems like stalling, no-start, or erratic shifting, the Powertrain Control Module (PCM) or Engine Control Module (ECM) may be at fault. These modules are the brain of your vehicle’s engine and transmission management. This guide explains what the PCM/ECM does, where it is located, what replacement involves, and how to address common failure symptoms. You will learn the factory-recommended procedures, including the required relearn and flash programming recovery steps. We also cover how pre-programmed replacement units can simplify the process, saving you time and avoiding dealer visits.
What the PCM Does in a 2000 Chrysler Sebring
The PCM (Powertrain Control Module) in the Coupe and the ECM (Engine Control Module) in the Convertible of your 2000 Chrysler Sebring are the central computers that control fuel injection, ignition timing, transmission shift points, and emissions systems. They receive input from sensors throughout the vehicle and adjust actuators to maintain optimal performance and fuel economy. When these modules fail, the engine may run poorly or not at all. For a reliable fix, consider replacement PCM/ECM for the Sebring that are built to factory specifications. Understanding the role of this module helps you diagnose issues accurately and avoid unnecessary part replacements.
Where the PCM Is Located and What Replacement Involves
The PCM or ECM in your 2000 Chrysler Sebring is typically mounted in the engine compartment, often on the driver’s side near the firewall or on the inner fender. Replacement involves disconnecting the battery, removing electrical connectors, and unbolting the module from its bracket. Book labor time for removal and replacement is 0.6 hours for the Coupe PCM, 0.7 hours for the Coupe ECM, and 0.4 hours for the Convertible (either module). After installation, a 0.5-hour relearn procedure is required to allow the module to adapt to your vehicle’s specific sensors and actuators. Access may require removing other components, so plan accordingly.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Powertrain Control Module R&R | Coupe | 0.6 hr |
| Powertrain Control Module R&R | Convertible | 0.4 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | Coupe | 0.7 hr |
| Engine Control Module R&R | Convertible | 0.4 hr |
Programming Requirements After Replacement
After installing a new PCM or ECM in your 2000 Chrysler Sebring, the factory procedure requires a flash programming recovery using a DRBIII scan tool, as outlined in TSB 18-037-05. This step is necessary to load the correct calibration and ensure the module communicates properly with the vehicle’s systems. However, when you choose a VIN-programmed replacement unit from Flagship One, the module arrives with the correct software already installed for your specific VIN. This eliminates the need for dealer-level programming and the relearn procedure, allowing you to install the module and get back on the road faster.
Symptoms of a Failing PCM
Common symptoms of a failing PCM or ECM in your 2000 Chrysler Sebring include a no-start condition, intermittent stalling, rough idle, misfire codes, and erratic transmission shifting. You may also experience a loss of communication with a scan tool, or the check engine light may illuminate with a stored P0601 internal module fault. Other signs include poor fuel economy, hesitation during acceleration, and the vehicle entering a limp-home mode. These issues can be intermittent at first, making diagnosis challenging. If you notice any of these symptoms, it is important to have the module tested or replaced promptly to avoid being stranded.
Module Trouble Codes on the 2000 Chrysler Sebring
The following module-internal trouble code is documented for the 2000 Chrysler Sebring PCM/ECM. This code indicates a fault within the module itself and often requires replacement rather than repair.

Protecting the PCM in Your 2000 Chrysler Sebring
- Maintain a healthy charging system; voltage spikes from a failing alternator can damage the PCM/ECM.
- Keep battery and ground connections clean and tight to ensure stable voltage to the module.
- Avoid jump-starting with a running vehicle; use a battery pack or follow proper jump-start procedures.
- Address any diagnostic trouble codes promptly to prevent secondary damage to the module.
- Inspect the module’s connector seals for cracks or moisture intrusion, which can cause corrosion.
- When performing electrical work, disconnect the battery to prevent accidental shorts.
Frequently Asked Questions
What is the difference between the PCM and ECM for a 2000 Chrysler Sebring?
For the 2000 Chrysler Sebring, the Coupe uses a Powertrain Control Module (PCM) that controls both engine and transmission functions. The Convertible uses an Engine Control Module (ECM) that primarily manages the engine. Both perform similar roles but have different labor times for replacement.
Can I replace the PCM/ECM in my 2000 Chrysler Sebring myself?
Yes, replacement is straightforward if you have basic mechanical skills. The module is located in the engine compartment and requires disconnecting the battery, removing connectors, and unbolting it. Book time is 0.4 to 0.7 hours depending on body style. However, you will need a DRBIII scan tool for programming unless you use a pre-programmed unit.
What does trouble code P0601 mean for my 2000 Chrysler Sebring?
P0601 is an internal control module fault code. It indicates a problem within the PCM or ECM itself, such as a memory or processor error. This code often requires module replacement because the internal circuitry cannot be repaired. A pre-programmed replacement unit can resolve the issue without dealer programming.
When your 2000 Chrysler Sebring’s PCM or ECM fails, you have two main options: have a dealer repair the original module (if possible) or replace it with a new or refurbished unit. Given the complexity of flash programming and the need for a DRBIII tool, many owners choose a pre-programmed replacement. This approach eliminates the relearn and programming steps, saving time and ensuring compatibility with your specific VIN.
Flagship One stocks a refurbished, VIN-programmed PCM for the 2000 Chrysler Sebring with a lifetime warranty, free shipping and no core charge. The full Chrysler Sebring module lineup covers other engine configurations as well.
Final Thoughts
The PCM or ECM in your 2000 Chrysler Sebring is critical for engine and transmission performance. Recognizing symptoms like no-start, stalling, or a P0601 code early can prevent breakdowns. Whether you choose a repair or replacement, using a VIN-programmed unit from Flagship One simplifies the process and gets your Sebring back on the road reliably.
