This valve is responsible for regulating the flow of oil to Cylinder 4 in the engine, ensuring proper lubrication and performance. When the voltage is out of range, it can lead to issues with oil delivery to the cylinder, potentially causing poor engine performance, misfires, and even engine damage if not addressed promptly.
Common Causes of P104B
- Faulty oil supply solenoid valve
- Wiring issues or poor electrical connection
- Low oil level or dirty oil
- Engine overheating
- Engine computer (ECU) malfunction
Symptoms of P104B
- Rough idling or engine misfires
- Decreased engine performance or power
- Illuminated check engine light
- Engine stalling or hesitation
- Increased fuel consumption
How to Fix P104B
- Begin by diagnosing the specific cause of the issue using a scan tool to confirm the P104B code.
- Inspect the oil supply solenoid valve and wiring for any damage or corrosion.
- Test the solenoid valve for proper operation and replace if necessary.
- Check and top up the engine oil level, ensuring it is clean and of the correct grade.
- Clear the fault codes and test drive the vehicle to ensure the issue has been resolved.
