I am unable to tell you exactly what is going on with your vehicle without more information, but I can give you the information I have available on the diagnostic trouble codes (DTC’s) that you have listed. The P0725 relates to the crankshaft position sensor. According to the testing flow chart, it suggests that there is more than likely a problem with either a failing crankshaft position sensor, or the wiring that is associated with it. As far as the P0455 goes, this code relates to a large evaporative emissions leak. This is normally observed when a gas cap has been left off, refueling while the engine is running, or an evap hose that has been compromised. A visual inspection may able to identify the origin for the fault, but more intense diagnostics may be necessary otherwise. If you feel you could use a hand in identifying and/or repairing the issues, contact a certified mechanic, like those available at YourMechanic.com.
