What causes a fuel pressure code on a Nissan Navara?
Fuel pressure problems. Any of these codes will generally be triggered due to low or high fuel pressure or abnormal fuel pressure pulses detected by the fuel pressure sensor. The ecm judges fuel amount passing through to the fuel rail by comparing SCV (Suction Control Valve) pulse to actual rail pressure as measured by the rail pressure sensor.
Why is my fuel pressure sensor not working?
This type of symptom will generally only be noticeable after the vehicle has been parked overnight. The fuel pressure sensor uses the 5v circuit to deliver a signal to the ecm regarding fuel pressure. It is not very common for this item to fail. If it did, it would need to be probed, and checked for power, ground and signal feed.
When to do a Nissan fuel pump reset?
You need to to do a fuel pump reset every time you do a fuel filter replacement this will give you better fuel economy and help save you money in future parts ie Injectors, and fuel cost’s. Subscribe to our channel and we will teach you every thing about the Nissan 4×4.
What causes low fuel pressure and stalling?
These can cause low fuel pressure and stalling. The fuel pressure relief valve, will open if fuel pressure becomes too high. This can happen if the scv is failing and also if an aftermarket performance chip is installed on the car. It will be a high pressure condition followed by a low pressure condition when the relief valve opens.

What causes low or high fuel pressure codes?
With these calculations the ecm can determine if fuel delivery is out of range with the comparison of expected vs actual. Some causes of these codes to be triggered are: low/high fuel pressure, SCV, fuel pump, air ingress into fuel system, fuel pressure sensor, fuel pressure relief valve, wiring.
