P0450, P0452 and P0453 on your Jaguar X-type

P0450, P0452 and P0453 on your Jaguar X-type is flagged when the computer sees a problem with the fuel tank pressure sensor. Your most likely problem is a fuel tank pressure sensor, but if you want to check it,all you have to do is connect a voltmeter at the connector, and you should see 5 volts with the key on (this is called reference voltage). If you don't then your problem lies in the circuit to the fuel tank pressure sensor.
