The Hyundai Code P0650 is an error code that indicates a Malfunction Indicator Lamp (MIL) Control Circuit issue. This code is triggered when the Powertrain Control Module (PCM) detects an open or short circuit in the MIL line, or if the contact resistance in connectors is too high. In some cases, the error code may be caused by a burned out MIL bulb. It is important to identify the cause of the code and take the necessary steps to fix it. This article will provide an overview of the possible causes and solutions for the Hyundai Code P0650.
Causes and Solutions for Hyundai Code P0650
| Cause | Solution |
|---|---|
| Open or short between MIL and PCM | Check the wiring and connectors for any damage or corrosion and replace if necessary. |
| High contact resistance in connectors | Clean the connectors and replace if necessary. |
| Burnt out MIL bulb | Replace the MIL bulb with a new one. |
| Faulty PCM | Replace the PCM with a new one. |
Open or Short Between MIL and PCM
When the Hyundai Code P0650 is triggered, it is important to check the wiring and connectors between the PCM and the MIL for any damage or corrosion. If there is any damage or corrosion, the wires and connectors should be replaced. If the wiring and connectors are in good condition, the contact resistance should be checked.
High Contact Resistance in Connectors
The contact resistance between the MIL and the PCM should be checked for any high resistance. If the contact resistance is high, the connectors should be cleaned and replaced if necessary. This will prevent the code from being triggered again.
Burnt Out MIL Bulb
If the MIL bulb is burned out, the Hyundai Code P0650 will be triggered. Therefore, it is important to replace the MIL bulb with a new one.
Faulty PCM
In some cases, the error code may be caused by a faulty PCM. If this is the case, the PCM should be replaced with a new one.
Conclusion
The Hyundai Code P0650 is an error code that indicates a Malfunction Indicator Lamp (MIL) Control Circuit issue. When the code is triggered, it is important to identify the cause and take the necessary steps to fix it. This article provided an overview of the possible causes and solutions for the Hyundai Code P0650. It is important to check the wiring and connectors, clean and replace the connectors if necessary, replace the MIL bulb with a new one, and replace the PCM with a new one if it is faulty.
