I own the vehicle listed above it is a Rider S Autotech C25 model. I took this car for engine wash then thereafter the car started jacking and lost drive power as drove back home. Allover a sudden the dashboard control light i.E "P" "R" "N" "D" "L" disappeared. I went back where the car was done engine wash and used pressure to blow off excessive water from control sensors. We switched on the engine the control lights came back but "D" light failed completely even after several trials.
At the moment the car gains drive power when I try to drive front and back the it shows "N" even when engaged to drive gear then it lost both drive and reverse power completely. Please advice what could be the problem with my car and God will bless you for your help.

Kind regards,

Francis

The transmission position sensor got wet which is causing the problem. Remove the connector and use compressed air to dry it out. If this doesn't work I would replace the switch

Here is a diagrams of where the switch is (below)

Please let us know what happens so it will help others.

Cheers

Dear Roy,

Thank you so much for your quick responds.

Now, I was also advised to remove the battery terminal which I did and it stayed detached for almost twenty four hours and when we reconnected we found the problem still there.

Then I removed the connector and did what you said and it worked! Thanks for the heads up the site is the best :)

Please advice.

Kind regards,

Francis.

Hi, who has a solution to this Nissan Serena's. I drove mine from Mombasa and whenever I approached the hilly parts the vehicle just lost power and have to park it for some twenty to thirty minutes and start again. It is so annoying. Please help.

Suddenly the some days ago I drove the car on a 160 km trip; after moving about 120 km the car started going off every time I want to pick up after slowing down until I reached my destination.
The following day; the behavior was the same, I moved about 140 km before it started going off every time I slowed down either due to traffic jam or speed humps etc.
When that happens; the break is stiff, the accelerator is dump.

I do not understand much of your terminology, but I get the impression the engine is stalling when you slow down after driving for some distance. A stalled engine will result in loss of power assist for the brakes, so that is to be expected. You will still have brakes, but you will need to push much harder on the pedal.

If it sounds like I have the description of the symptoms correct, an elusive cause is a collapsing or plugged pickup screen inside the gas tank. Depending on the type of fuel delivery system your car uses, many of them pump a much higher volume of fuel when the car is coasting and slowing down, so that is when the plugged screen causes the symptoms. Most of that high volume of fuel goes right back into the tank, but the restricted screen causes fuel pressure to drop.

To verify if I am right, you need to attach a fuel pressure gauge so you can watch what happens to fuel pressure when the problem occurs. This has happened to me three times with two cars. In the second one, normal fuel pressure varies between forty five to fifty five pounds, and the symptoms showed up when it dropped to less than twenty pounds. Some engines will not run when the pressure drops just five or ten pounds. I run the hose for the gauge under the rear edge of the hood, then I clip the gauge under a wiper arm where I can see it from inside the car.

The additional clue is that screen will stretch out again and let fuel pass if you let the car sit on the side of the road for ten minutes. With my car, I could drive up to about another five miles before the problem occurred again.

Hello, my Nissan Serena 2008 has been losing power over hills. As it approaches the hill it slows right down and in some cases stops. It runs great on the highway though. I've gone to mechanics and they have already done transmission check, changed T oil, engine oil, spark plugs, gas pump and filter, none of which fixed the problem. The diagnostic machine is saying "lien fuel mixture" I think. I urgently need some help! It has cost me too much already.

A lean fuel mixture can be caused by a few things. Have you checked fuel pump pressure? Have you checked for engine vacuum leaks?

I'm not sure if the pump pressure was checked but I know that it was changed and the problem is still there. I don't believe the engine vacuum was checked either. I'll check that one next. Are you suggesting that I check the fuel pump pressure even though the pump has been changed?

Since the mixture is lean, I would suggest checking it. Also, has the coolant temp sensor been tested?

If I don't hear from you, Have A GOOD CHRISTMAS!

I have a 1997 1.6 petrol nissan serena, when warm it does have Lack of acceleration, chugging, hesitating sometimes feels like it has stalled then catches again, first changed plugs and air filter and went ok for a few months, then started again changed plugs again, leads and coil no joy this time, now I am thinking it was the change of air filter that cured it for a few months-so could this be an air flow meter problem? How can I check if it is and if so can it be repaired or just change it.

You need a scope to check it. Would be easier for a shop to verify it for you.
It cannot be repaired only replaced if it is at fault.
Check the coolant sensor and make sure it is working correctly as well.
