Conditions for Setting the DTC

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

P018B 

The engine control module does not detect a normal fuel pressure change of at least 30 kPa (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.

P018C 

The engine control module detects that the fuel pressure sensor voltage is less than 0.2 V for 1 s.

P018D 

The engine control module detects that the fuel pressure sensor voltage is greater than 4.8 V for 1 s.
