Oh wow I don't even know where to start. The second I came home with the car for $32,995 off the used dealership it was a horrific disaster. I have replaced the rear fuse panel 2x already(water damage). The amp was fried from water damanage. The ambient lights and screen along with the gear lights only sometimes work. My morimoto aftermarket headlights wiring all have completely melted and needed to be replaced and that is just the small things. The car has always had severe driving malfunctions. These include: Jerking when putting into gear (any gear), shudders, it will rev up when i am braking, usuallu after a small hill or bump it will get really loud like it is in a much higher gear, it…

U0109: questions drivers ask

What does code U0109 mean?

U0109 is a generic OBD-II network code. Its standard definition is "Lost Communication With Fuel Pump Control Module". The code tells you which system set the fault, not which part failed; the owner reports on this page show what it meant in practice for 7 car models.

Which cars get code U0109 most often?

In NHTSA owner complaints, U0109 is mentioned most for the Chevrolet Camaro (1), Chevrolet Cruze (1), Ford Expedition (1), across 7 models and model years 2012 to 2017. Popular models collect more reports because more of them are on the road.

Is there a recall for code U0109?

No NHTSA recall text names U0109 directly. 5 recalls on the cars that report this code concern the same component owners name most (Electrical System); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.

What should I do if my car shows U0109?

Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.

How this page was made

CarHooq read the text of every owner complaint filed with NHTSA for 19 US and European brands (model years 2012 onwards) and picked out the diagnostic trouble codes owners wrote down. This page lists every mention of U0109 (including sub-code forms such as U010987). The definition is the generic SAE J2012 wording; a carmaker may use the code slightly differently. Nothing here is a diagnosis. Data: NHTSA Office of Defects Investigation (public domain), retrieved November 3, 2026. How CarHooq reports are made.
