Check engine light comes on they said its a sensor? What sensor is it engine light goes off and on
Hi
Thanks for using
FixYa. P0453 code means Fuel
Tank Pressure (FTP) Sensor Circuit High Voltage and it seems that you’ll need
to get the Fuel Vapor Pressure Sensor replaced. P0641 code means that the
voltage state is invalid for 5 Volt Reference 1 Circuit. To resolve this you’ll
need to check the A/C pressure
sensor as 5 volt reference circuit 2700 may short to ground at the A/C hose,
also check its wiring. The typical cost to get these issues fixed by a
professional is around $250 including labor. Please do accept the solution if
the issue is resolved or post a comment for further assistance.
Thanks

It turns out the fuel pump needed replacing and as I understand, the FTP was not adequate. Cost: $500.00. AC Delco part was $365, Labor $180.
