What is the solution for the P0606 trouble code?
2 Answers
Delete the P0606 trouble code and check if it reappears. This trouble code indicates a malfunction in the Electronic Control Unit (ECU), requiring replacement of the electronic control module or original factory parts. After the vehicle's issue is resolved, the trouble code must be cleared. Code clearance must be performed according to the specified method for the particular vehicle model.
I also encountered the P0606 trouble code when repairing my car before. Actually, this indicates a problem with the internal processor of the engine control unit (ECU), and it needs proper attention. First, check if there are any poor connections in the ECU's power and ground wires—sometimes false alarms occur due to wiring issues. If the wiring is fine, there's an 80% chance you'll need to try reprogramming the ECU, which requires professional equipment to connect to the vehicle's computer. If that doesn’t work, the only option is to replace the entire ECU module. Last time at the dealership, I saw a Hyundai where reprogramming didn’t help, and they ended up spending over 2,000 yuan to replace the module before fixing it. A reminder to everyone: don’t delay with this fault or try to handle it yourself—take it to an experienced repair shop. Otherwise, sudden engine stalling could be dangerous.
