Nissan Navara D40 - SCV replacement and ECU reset

Replacing the suction control valve (SCV) on my 2007 Nissan Navara (YD25DDTi) and reseting the engine control unit (ECU)
Possible faulty SCV symptoms:
1. Intermittent injector rattle usually at around 2000 rpm
2. Stalling on idle
3. Jerking / loss of power
4. DPF light coming on
5. Cruise control failing to maintain constant speed
Notes:
- Replacement can be done from above thru the engine bay but you'll mostly be doing it blind. It's recommended to move the oil dipstick out of the way when done this way.
- The electrical connector can be tight and hard to grip. Do NOT pull from the wires, that's literally illegal.
- Do NOT let dirt get into the fuel pump.
- Make sure the new SCV seats properly. Do not force it or you'll pinch the o-ring. It sits snug but not tight.
ECU reset:
- Ignition on, wait 3 seconds
- Pump accelerator 5 times, wait 7 seconds
- Hold accelerator for 10 seconds
- Check engine light should start flashing, wait about a minute
- Turn the ignition off
- Start the engine
(The "beep" heard on the video during the reset is not related to the procedure, it's coming from my dashcam)

Qual foi o motivo pela troca ? Tenho uma 2008 cambio automático,e esta apagando quando engreno marcha D ou R .

SCV significa Válvula de Controle de Sucção e controla a pressão do combustível no trilho de combustível. A estagnação é um sintoma comum de uma SCV com defeito, mas não tenho certeza se é o problema no seu caso. Pode ser algum outro sensor relacionado à transmissão automática.

Have you looked at neutral switch?

@@philtowle4683 No, but I'll definitely look into it. Thanks for the tip!

Ya, menetapkan semula membuat ECU belajar semula semua bahagian dan sensor kenderaan, termasuk SCV.
