Too Much Fuel Consumption 407 Peugoet Case Study and Fix | High Fuel Consumption Troubleshooting 

Hi, thanks for your video, my Peugeot 807, with EW10A engine consumes fuel like that too, have changed O2 sensor, fuel pump and still like that. I will like to send you the scan that i did for your assistance. Thanks.

Thanks for this post. I have subscribed. My engine EW10 also has terrible fuel consumption. I havent looked at the live data, but I have a brand new air intake temperature sensor - the one that fits on the throttle. I want to fit and see if it will help. Last scan showed oxygen sensor problem but I havent had it checked yet.

so the bad fuel consumption must be from bad air temp sensor and the car thinks engine is very cold therefore it will send more fuel in the combustion chamber. id be looking into replacing air temp sensor first to see if the injector wil send less fuel

My peugeot 407 have too much fuel .. and on scanner there is no fault ..what is the problem?!! it is make 6.5km per 1litre with AC active
