Error on sensing system

P145c and P0497

Ok. Not to sound harsh, just being honest, you need a new technician. This is a simple issue, and testing should be done in an hour. Take it to an independent shop, we have lots of them listed, and have them test the vehicle. You may have a loose electrical connection at the fuel tank pressure sensor, the engine control module, the EVAP purge solenoid, the EVAP canister vent valve, or there is blockage in one of the lines, or one of those components has failed. It is typical of the purge valve or vent valve to fail.

Also.... why is he cleaning the brakes system? That should only be done as factory scheduled maintenance as listed in your owners manual. What cylinder is he cleaning? Injectors?
