According to Vadis it maps to EFI-621.. Signal high. If you've verified the supply has power (5V not 12V, pin 3 so left when looking at the pins), have you verified 0 Ohm resistance on the ground (middle pin)?

Diagnostic trouble code (DTC) information EFI-621

Condition

Diagnostic trouble code (DTC) EFI-621 (Fuel tank pressure sensor, signal) is stored if the engine control module (ECM) receives a signal from the tank pressure sensor corresponding to a pressure above 2.95 kPa (signal high) or below -2.88 kPa (signal low).


Substitute value
-leakage diagnostic is disabled.


Possible source

Signal too high
-short-circuit to supply voltage in signal cable
-open-circuit in signal cable or ground lead
-contact resistance in terminals
-defective fuel tank pressure sensor.

If you're not driving it "like its stolen," are you really driving?
