Peugeot 807 throttle valve issue

My 2005 Peugeot 807 diesel has a problem. At 264927 km, the throttle valve seems defective, causing higher fuel consumption and poor starting. I suspect the accelerator pedal module. Any ideas?

A 2005 Peugeot 807 diesel exhibited higher fuel consumption and poor starting, suspected to be due to a defective throttle valve or accelerator pedal module. Cleaning the throttle body was suggested as a potential solution, but a diagnostic check revealed the accelerator pedal module was faulty. Replacing the module resolved the issue, resulting in smooth car operation.

Interesting. My 807 had similar symptoms. It turned out to be gunk around the throttle valve. Have you tried cleaning the throttle body and checking the air intake before replacing the accelerator pedal module? What's the throttle position when this happens?

Thanks, I hadn't thought about cleaning the throttle body. What cleaner did you use, and did you remove the valve completely? Also, how do I check the throttle position?

I didn't remove the valve, but I used carburetor cleaner and a soft brush to carefully clean it. Since you mentioned a potentially defective module, get a diagnostic check at a workshop first. Make sure it's not electrical before spending money. Cleaning helped me, but your problem might be more complex.

Understood. I consulted a workshop, and the accelerator pedal module was indeed faulty. The replacement cost 205€. The car runs smoothly now.
