How do I fix the code P0601 on my car?
The most common fix for this error code is replacing or reprograming the PCM. In some few cases, dealers may reflash the PCM and get it working. But most often than not, the code means the PCM must be replaced and reprogrammed. This is why it’s important that you take your vehicle to its dealership for this problem.
What causes P0601?
Diagnostic trouble code (DTC) P0601 stands for “Internal Control Module Memory Checksum Error.” It is triggered when the powertrain control module (PCM) detects an internal problem, typically a failed Memory checksum test. The PCM’s Memory checksum test is performed regularly.
How do I fix code P0605?
What repairs can fix the P0605 code?
- Repairing a faulty ground or power supply such as corroded components and damaged wiring.
- An Engine Control Module update, reprogramming or reflash (if applicable)

What is code P0606?
Code P0606 is triggered when there is a fault found in the processor internal to the Engine Control Module (ECM)/Powertrain Control Module (PCM). In most cases, it is a faulty ECM/PCM but you should always check powers and grounds to verify there isn’t a wiring problem before replacement of the control module.
