Specification Pressure(kPa)Output Voltage(V)500.36002.511004.5
Fail-Safe Mode ItemFail-SafeDuty (%)85 If the fuel pressure sensor malfunctions, it enters fail safe mode. This means that the fuel pressure rises to match the increasing value of the current level and the pressure in the low pressure fuel line remains static despite the rising fuel pressure.
Inspection 1. Turn the ignition switch ON. 2. Connect the GDS. 3. Emit intensive light toward the photo sensor using a lamp, and check the output voltage change. 4. The voltage will rise with higher intensive light and fall with lower intensive light.
