1. IG "OFF" & connect GDS.
2. ENG "ON" and Race the accelerator pedal at idle and Monitor "FTPS" parameter is changing while PCSV is operating on the service data.

Specification :Fuel Tank Pressure is O.K if pressure changes more than 0.2 while racing accelerator padal.








Fig.1) Sample data at idle with no acceleration (It can be different based on purging state)
Fig.2) Sample data at idle with acceleration (It can be different based on purging state)
3. Does the FTPS change while racing the accelerator pedal at idle ?
