Code P1017 Description
The P1017 code refers to an issue with the Valvetronic eccentric shaft sensor plausibility in the vehicle's engine. The Valvetronic system is a variable valve lift system that allows for better fuel efficiency and performance by adjusting the intake valve lift. The eccentric shaft sensor plays a crucial role in monitoring the position of the Valvetronic eccentric shaft, which controls the valve lift.
Common Causes of P1017
- Faulty sensor: The most common cause of the P1017 code is a malfunctioning Valvetronic eccentric shaft sensor.
- Wiring issues: Damage to the sensor's wiring or poor electrical connections can also trigger this code.
- Mechanical issues: Problems with the Valvetronic eccentric shaft itself or related components can cause sensor plausibility issues.
- Software malfunction: Occasionally, a software glitch in the engine control unit can lead to erroneous sensor readings.
Symptoms of P1017
- Rough idling: The engine may idle roughly or inconsistently when the Valvetronic eccentric shaft sensor is not functioning correctly.
- Reduced power: The vehicle may experience a loss of power, especially during acceleration.
- Poor fuel economy: A faulty sensor can cause the engine to run inefficiently, resulting in decreased fuel efficiency.
- Engine misfires: The engine may misfire or run unevenly due to incorrect valve lift adjustments.
- Check engine light: The most common symptom of this issue is the illumination of the check engine light on the dashboard.
How to Fix P1017
- Diagnostic scan: Begin by using a diagnostic scanner to read the fault codes and confirm that the issue is indeed related to the Valvetronic eccentric shaft sensor.
- Sensor replacement: If the sensor is found to be faulty, it will need to be replaced with a new one.
- Wiring check: Inspect the sensor's wiring and connections for any damage or corrosion, repairing or replacing as needed.
- Clear codes: After the repair is completed, clear the fault codes from the ECU to reset the system.
- Test drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the engine is running smoothly.
Cost to Fix P1017
The cost of repairing a Valvetronic eccentric shaft sensor plausibility issue can vary depending on the make and model of the vehicle, as well as the location and labor rates of the auto repair shop. Typically, the cost of a new sensor can range from $100 to $300, with additional costs for labor and any necessary wiring repairs. In total, the repair for this issue could range from $200 to $500 or more. It is advisable to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on your specific vehicle.

Frequently Asked Questions about P1017 Code
1. What does the OBDII code P1017 mean?
P1017 indicates a problem with the Valvetronic eccentric shaft sensor, specifically a plausibility issue where the sensor's readings are inconsistent or outside the expected range.
2. What are common symptoms of the P1017 code?
Symptoms may include a rough idle, reduced engine performance, poor fuel efficiency, difficulty starting the engine, and the check engine light being illuminated.
3. What causes the P1017 code to appear?
Common causes include a faulty eccentric shaft sensor, wiring issues such as damaged or corroded connections, a malfunctioning Valvetronic actuator, or mechanical issues with the eccentric shaft.
4. Can I drive with a P1017 code?
Driving with a P1017 code is not recommended, as it can lead to reduced engine performance and may cause further damage to Valvetronic components if not addressed promptly.
5. How is the P1017 code diagnosed?
A technician will use a scan tool to read the code and monitor live data, inspect the eccentric shaft sensor and its wiring, and check for mechanical issues with the Valvetronic system.
6. How do I fix the P1017 code?
Repairs may involve replacing the eccentric shaft sensor, repairing or replacing damaged wiring, recalibrating the Valvetronic system, or addressing mechanical faults in the eccentric shaft assembly.
7. How much does it cost to fix a P1017 code?
Repair costs vary, but replacing the eccentric shaft sensor typically ranges from $300 to $800, including parts and labor, depending on the vehicle model and repair complexity.
8. Does the P1017 code require recalibration after repairs?
Yes, after replacing the sensor or performing repairs on the Valvetronic system, recalibration using a diagnostic tool is often necessary to ensure proper operation.
