Good evening Seniors, please I have issue with my Nissan Pathfinder 2001 model. I noticed that the engine wasn’t complete so I took it to my Rewire to help me service/changed the Nozzles to a Tokunbo and we changed the 6 plugs too but still the engine didn’t work well. We later discovered that it’s only 3 cylinders that are working out of the 6. And this have given us worried of what could have happened and this led us to even changed the brain box but no luck yet. So we suggest that we should scanned the car to know where the problem(s) is. The scanner said the problem is P1165 which is Swirl Control Valve Control Vacuum Switch. I don’t know what to do anymore. Please my brothers help me out because I’m really losing out on this car. Thanks

Your ride is tired of being a V6 and wants to downgrade from V6 to i3.
Accept it in good faith!

if the 3 cylinders that are not working from one bank of the v6,it is time to bring the one top cylinder down and change the valves,also check the ignation coils if it is firing, mostly the cause of this type of valve failure is poor oil pressure getting to the top cylinder,let them bring out the bottom plate and wash the oil pump filter to increase pump pressure

Bad suggestion.
Don't ever start opening up engine indiscriminately based on mere what u feel but what u have confirmed 100%.Beside poor oil pressure will affect all cylinder not just 3 cylinder alone .

3 cylinders just going down like that is not mere
coincidence but certain denominator that is common to all 3 cylinders that is affected ,if it restricted to a single cylinder bank then it time to check the following item:timing ,power feeds and ground to the ignition and injector etc

Bad sensor or bad expired spark plugs

if the ignition coils are good ,the spark plugs are good and nozzles are firing,what else do you think that can make 3 cylinders in one bank of a v6 engine to stop working?if it is not valve what else can cause such problem?and what can make the valves to fail at once,if not poor lubrication,I have worked similar problem in my previous car that's why I know.

Since my audience here is a diyer with his only training and learning based solely "on working on similar problem on his car ",and his mind so closed to accept superior knowledge ,I think I am done ,no comment .
Continue to wallow in your "knowledge"

we are here to learn from the experiences of other people and I am not arguing about your superior knowledge,just that I have had similar problem and I just shared how it was solved,it is left to the mechanic to decide how he will work the car,

The haste with which Nigerians change their ECU's is alarming. Some of these strange car behaviours mostly relate to sensors and not the ECM. It's difficult to get a perfectly matching ECU for most vehicles, which is why changing the ECU mostly result in even more bizarre behaviours in most vehicles..The owner gets so frustrated that the car is put on sale..Many Nigerian used cars come with a swapped ECU and the buyer inherits a practically psychotic vehicle.

that psychotic description set me laughing when I remembered my previous car an Acura RL,a car that I got ignorant about what flood damage means until strange things started happening at night,AC blower can switch on at night, headlights,fog lights, windows can roll down if you switch on ac,the electric boot can open if you switch on headlamp and the most bizzare is the satellite emergency trying to call the response team in US that the car has an accident,this problems defied and stumped electricians , saltwater damage can cause real serious electrical problems that will defy explanation.

Lol! That's the downside of miniaturization achieved with integrated circuits. Modern cars are full of interlinked electrical and electronic systems..A malfunction in one part would affect another seemingly unrelated operation. It means that even error codes in scanners need expert interpretation, even then, it sometimes stumps even the dealership...and cars are getting even more complicated, leaving unserious countries like Nigeria far behind.
