I KEEP GETTING WARNING LIGHT THAT, DRIVER SIDE AIRBAG FAULT ENGINE CODE P0073 AND VEHICLE OVER-SPEED CONDITION ENGINE CODE PO297. IT COME ON WHEN DRIVING.
2019 Ford Fusion Hybrid SE. Vehicle experienced a “Stop Safely Now” warning with hybrid system shutdown, occurring both while driving and while parked/idling, causing jerking symptoms.

I recently had the following situation. Tuesday, Dec. 13th, 2022 a big storm hit, showered snow on us ALL day. My Jeep was parked with the passenger side to the north... just setting the scene.

P0073: questions drivers ask
What does code P0073 mean?

Is there a recall for code P0073?

What should I do if my car shows P0073?
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 P0073. The definition is the generic SAE J2012 wording; a carmaker may use the code slightly differently. Nothing here is a diagnosis.
