PO453 V70-XC70 1998

I believe you're right. Its the pressure sensor, though it shouldn't be tooo hard to diagnose.

First step, get to the sensor (its outside the tank), carpet and hatches, fold down the seats, not terrible as far as tear downs go..

Ignition off, also wait to disconnect for 4-5 minutes after you turn the car off..
Check resistance between the middle pin and the ground. It should be 0 Ohm. Also make sure the connector is clean there and on the receiving end of the fps.

If that checks out then check voltage between the left pin, if the connector is facing you, and the ground. It should be 5V.

If that checks out too, next step is the sensor.
