• Difference between barometric pressure and exhaust pressure
while engine stopped.
• Difference between barometric pressure and exhaust pressure
is excessively low while engine is running.
if there is no other codes then check cable is not damaged. then check voltage at sensor, should be 5v. i would also check earths and also if you have a dual battery setup. also check turbo.
did you replace the correct sensor? its not the dpf pressure sensor, its up on the engine. afaik its the pre turbo sensor on the exhaust manifold.
