Fuel Pump (FP), Workload (%)

Measurement range 0 - 100 %.

The value shows the PWM signal between the engine control module (ECM) and the fuel pump (FP) control module. A higher pulse ratio gives a higher fuel pressure. At 400 kPa the pulse ratio must be approximately 35% (±5%). The values are not relevant if the battery voltage is too low.
