I bought a new catalytic converter on the vehicle and had old parts replaced. There aren’t any leaks. I received an engine diagnostic test and still comes back with P0240 code.
P0240 code keeps coming up but the catalytic converter was changed and the cylinders at the dlrshp. This has been an ongoing issue for over 3 years.
My truck started to throw codes p0240 and p0430 when my truck hit 81000 miles. I am now at 141000 miles. I have since replaced both of my catalytic converters, all 4 of my O2 sensors and I still have the same p0240 and p0430 codes. I also took my truck into ford on Feb 26, 2025 for the recall on my PCM reprogramming. They claimed to have redone the programming but ever since they did that, I now have shifting problems, surging, clanking, hard shifting, random and sporadic shifting with no end in sight. This should be addressed by Ford TSB 24-2101 but again, they did nothing and claim there is nothing wrong with my truck. I have had a fluid replacement and filter replacement with no issues…
P0240: questions drivers ask
What does code P0240 mean?
P0240 is a generic OBD-II powertrain code. Its standard definition is "Turbo/Super Charger Boost Sensor 'B' Circuit Range/Performance". 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 3 car models.

Is there a recall for code P0240?
No NHTSA recall text names P0240 directly. 2 recalls on the cars that report this code concern the same component owners name most (Power Train); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows P0240?
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

This page lists every mention of P0240. The definition is the generic SAE J2012 wording; a carmaker may use the code slightly differently. Nothing here is a diagnosis.
