Malfunction Threshold

The output from the fuel tank pressure sensor is -4 kPa (-1.0 in.Hg, -25 mmHg)*, -3 kPa (-0.9 in.Hg, -25 mmHg)** or less for at least 1.04*, 8.00** seconds.

* : Elapsed time after the FTP sensor output exceeds the malfunction threshold.

** : Excessive negative pressure is detected.
