Conditions for Setting the DTC

WARNING: This page is about a different variant/trim than selected.

The chassis control module does not detect a change in the fuel pressure of at least 30kPa (4.4 psi) when the fuel pump is operating. The fuel pressure sensor performance diagnostic provides a means to detect fuel pressure sensor output that is stuck within the normal operating range of the sensor.
