P0606 – ECM/PCM Processor Fault
Introduction
Encountering the P0606 code in your Chery? Here is a complete guide to its causes, symptoms, and solutions.
**The P0606 error is often linked to a faulty Engine Control Module (ECM) or Powertrain Control Module (PCM) processor**, which can significantly impact engine performance. **The severity level of this code is medium to high**, and **it is recommended to address the issue as soon as possible** to prevent further damage to the engine or other components.
The technical meaning of the P0606 code is that the ECM/PCM processor has malfunctioned, which can affect the engine’s overall performance and may be associated with other systems such as the transmission, fuel system, or ignition system.

Real-World Driving Scenarios
When driving with the P0606 code, the driver may experience issues such as engine stalling or hesitation, particularly during cold starts, acceleration, or when driving in heavy traffic. The code may also be triggered during idle, and the driver may notice changes in fuel consumption.
Diagnostic Steps
To diagnose the P0606 code, the following steps can be taken:
1. Inspect the ECM/PCM and its connections for any signs of damage or corrosion.
2. Use a scan tool to analyze the ECM/PCM data and monitor for any error messages.
3. Check the wiring and circuitry related to the ECM/PCM for any shorts or issues.
4. Perform mechanical checks on the engine and other systems to rule out any underlying issues.
Common Diagnostic Mistakes
Common mistakes when diagnosing the P0606 code include:
1. Failing to inspect the ECM/PCM and its connections properly.
2. Not using a scan tool to analyze the ECM/PCM data.
3. Not checking the wiring and circuitry related to the ECM/PCM.
4. Not performing mechanical checks on the engine and other systems.
5. Replacing the ECM/PCM without properly diagnosing the issue.
When Not to Replace the Sensor
Replacing the sensor may not solve the issue if the problem lies with the wiring, vacuum leaks, or ECU logic. In such cases, it is essential to address the underlying issue before replacing any components.
How to Fix
