Code P1019 BMW Description
The P1019 BMW code indicates a problem with the Valvetronic eccentric shaft sensor power supply being too high. The Valvetronic system is a variable valve timing technology used by BMW to improve engine performance, fuel efficiency, and emissions. The eccentric shaft sensor is a crucial component of the Valvetronic system, responsible for monitoring the position of the eccentric shaft to ensure proper valve timing.
Common Causes of P1019 BMW
- Faulty eccentric shaft sensor
- Wiring or connection issues
- Voltage supply problems
- ECM software malfunction
- Mechanical issues with the Valvetronic system
Symptoms of P1019 BMW
- Rough idling or engine misfires
- Decreased fuel efficiency
- Loss of power or acceleration
- Check Engine Light illuminated
- Engine stalling or hesitation
How to Fix P1019 BMW
- Begin by performing a thorough diagnosis to pinpoint the exact cause of the high power supply to the eccentric shaft sensor.
- Inspect the wiring and connections related to the sensor, looking for any signs of damage or corrosion. Repair or replace as necessary.
- Test the voltage supply to the sensor and ensure it is within the manufacturer's specified range. Address any voltage irregularities.
- If the sensor itself is faulty, replace it with a new, OEM-approved part to ensure proper functioning.
- Clear the diagnostic trouble codes from the ECM and perform a test drive to verify that the issue has been resolved.
Cost to Fix P1019 BMW
The cost of repairing a Valvetronic eccentric shaft sensor power supply high issue can vary depending on the specific cause of the problem and the labor rates in your area.

Frequently Asked Questions about P1019 BMW Code
1. What is OBDII code P1019 in a BMW?
OBDII code P1019 in a BMW refers to "Valvetronic Eccentric Shaft Sensor Power Supply High," indicating that the power supply voltage to the eccentric shaft sensor is higher than expected by the engine control module (ECM).
2. What are the common symptoms of code P1019 in a BMW?
Common symptoms include a check engine light, poor engine performance, irregular idling, and in some cases, the engine failing to start.
3. What causes the P1019 code to appear in a BMW?
The P1019 code can be triggered by several issues, including a faulty eccentric shaft sensor, wiring issues like shorts to power in the sensor circuit, or problems with the ECM itself.
4. How can I troubleshoot and fix the P1019 code in my BMW?
To fix the P1019 code, start by inspecting the wiring and connectors leading to the eccentric shaft sensor for any signs of damage or corrosion. If the wiring is intact, consider testing the sensor itself and replacing it if it is faulty. If the problem persists, further diagnostic work may be needed to check the ECM.
5. Is it safe to drive a BMW with the P1019 code?
While you may be able to drive with the P1019 code, doing so can lead to reduced engine performance and potential damage if the underlying issue is not addressed promptly. It is advisable to have the vehicle checked and repaired as soon as possible.
6. What tools are needed to diagnose the P1019 code on a BMW?
Diagnosing the P1019 code typically requires a digital multimeter to check for voltage levels and an OBDII scanner to read the code and monitor live data from the eccentric shaft sensor. Advanced diagnostic tools may also be needed for deeper analysis.
7. Can a faulty battery or charging system cause the P1019 code in a BMW?
Yes, a faulty battery or issues with the charging system can lead to high voltage levels that might trigger the P1019 code. It’s a good idea to check the battery and charging system as part of the diagnostic process.
8. How much does it typically cost to repair the P1019 code in a BMW?
The cost to repair the P1019 code can vary widely depending on the root cause. Replacing an eccentric shaft sensor can cost anywhere from $300 to $600 including parts and labor, but prices can be higher if additional issues like wiring repairs or ECM replacement are needed.
9. What is the role of the eccentric shaft sensor in a BMW?
The eccentric shaft sensor monitors the position of the eccentric shaft, which adjusts the intake valve lift. This information is crucial for the ECM to control engine timing and performance efficiently.
10. How often do eccentric shaft sensors fail, leading to the P1019 code?
While eccentric shaft sensors are generally reliable, they can fail due to wear and tear, environmental factors, or electrical issues, especially in higher mileage vehicles. Regular maintenance and inspections can help prevent unexpected failures.
