What does this mean?

Interpretation of OBD2 Code P0456 Volvo:
The Powertrain Control Module (PCM) periodically performs various tests on the EVAP system. OVD II’s EVB enhancement systems are in place to prevent oil leaks from the atmosphere, instead washing them in the engine for combustion. Regular testing is performed by PCM to monitor how the print is printed. PCM controls EVAP pressure by checking the tank top sensor (FTP). The recorder shows a slight loss in the EVAP system, this number is set.

Possible Answers

First, using a probe switch turn on the air filter, sealing the machine. Then check the oil filter sensor (FTP). If the system does not print properly, the numbers will not be the same. If not, the compression machine has also shown this. If the process is slow, use a smoke detector and make sure that smoke escapes from each EVAP system. Wherever smoke comes out of the system, that’s wrong. Do not force the EVAP machine with air. Doing so can impair cleaning and removal of the solenoids in the system.
