Arkana Jerking Acceleration Whistling Noise

The symptoms you describe – check engine light illumination, jerking during acceleration, unusual whistling and hissing sounds, idling instability potentially leading to engine stall, increased fuel consumption, and reduced engine power – collectively indicate a potential anomaly within the engine's air intake or forced induction system. Given your hypothesis of a faulty boost pressure sensor, one must consider the possibility of a defective cable or plug connection to said component. Could you provide further detail regarding any diagnostic procedures you have executed?

Thanks for the quick response! I haven't done any diagnostics myself beyond visually checking for obvious loose connections or damaged hoses around the intake manifold. What kind of diagnostic procedures would you recommend? Is there a way to test the boost pressure sensor itself?

In response to your inquiry, while advanced diagnostics necessitate specialized equipment, a meticulous inspection of the sensor's wiring harness and connector is advisable. Corrosion, damage, or loose connections can indeed disrupt the sensor's functionality. However, given the constellation of symptoms and the potential for consequential engine damage, I would recommend a comprehensive diagnostic assessment at a qualified automotive workshop. They possess the requisite tools to accurately evaluate the sensor's output and the overall integrity of the intake system.

Thanks, I appreciate the advice! I took it to the shop, and you were right. Turns out it was a faulty connection to the boost pressure sensor. They replaced the connector and everything is running smoothly again. Total cost was 95€ Thanks again for pointing me in the right direction!
