P1019 BMW Code - Valvetronic Eccentric Shaft Sensor Power Supply High
Quick Answer
The Valvetronic System is a variable valve lift system that, in combination with variable valve timing, allows infinite adjustment of the intake valve timing and duration. Common causes include Reluctor on Valvetronic Eccentric Shaft Sensor poor installation, Faulty Valvetronic Eccentric Shaft Sensor, Valvetronic Eccentric Shaft Sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

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.
