P1017 Code - Valvetronic Eccentric Shaft Sensor Plausibility

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.

Code P1017 Description

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. The system helps improve fuel economy and emissions and negates the need for a throttle body in regular use. The Eccentric Shaft Position Sensor is used as a feedback for the Valvetronic Eccentric Shaft. The Valvetronic Eccentric Shaft is actuated by Valvetronic Motor and in return controls the variable intake valve lift. The Eccentric Shaft Sensor is mounted to the cylinder head beneath the valve cover. The Diagnostic Trouble Code (DTC) will set if the Valvetronic Eccentric Shaft Sensor is not to factory specifications.

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.

9. What tools are needed to address the P1017 code?

Common tools include an OBDII scanner with advanced diagnostic capabilities, a multimeter for testing wiring, and possibly specialty tools for working on Valvetronic components.

10. Can a dirty or clogged engine cause the P1017 code?

While not a direct cause, excessive carbon buildup in the engine can strain the Valvetronic system and contribute to issues leading to a P1017 code. Regular maintenance is important.
