Insignia high fuel consumption

I'm having trouble with my 2016 Vauxhall Insignia gasoline engine. Fuel consumption is higher than usual, and it's occasionally hard to start. The car has 141873 km on it. Could this be a defective throttle valve? I checked the air intake and control valve, but they look fine.

A 2016 Vauxhall Insignia with high fuel consumption and occasional starting difficulties may have a defective throttle valve. However, a faulty accelerator pedal module could also cause these issues by affecting throttle position readings. A diagnostic scan is recommended to identify the problem accurately. In this case, the accelerator pedal module was confirmed as faulty and repaired at a cost of 205€.

A throttle valve issue could be the problem, given those symptoms. Have you thought about a defective accelerator pedal module? That could mess up the throttle position readings and cause similar issues.

Thanks for the suggestion. Is there an easy way to test the accelerator pedal module or throttle position sensor before I replace anything?

Testing varies, but a diagnostic scan is the first step. Faulty readings from the accelerator pedal module point to a problem. Given the potential complexity, I'd suggest a workshop visit for diagnosis and repair. It will save time and potential headaches.

I took it to a shop, and they confirmed the accelerator pedal module was faulty. The repair was 205€, including parts and labor. Thanks for the help.
