How to test idle valve on nissan almera

This is the reversing light switch. For $18 it is worth swapping out for a new one, but my feeling is that is something inside the transmission that is not in the right place that actuates it. Hopefully, you might even find it has come loose.

Having said that, this link say the switch does both neutral indicator and reversing light. That gives more reasoning that the switch is faulty.

You will need to get a Good Mechanic to look at this. There are 3 completely different problems here so it will need to be properly checked out. I've listed the Trouble Code definitions below.
-The knock sensor looks for signs of the fuel igniting at the wrong point in the sequence.
-The Crankshaft position sensor checks the pistons are in the correct position for the engine electronics to be in the correct sequence.
-The Air Control system is a set of valves that adjust air flow through the engine when running at different speeds. (Slow needs less air, fast needs more air).
Knock Sensors and Crankshaft Position Sensors can be in some ridiculous places on an engine and usually need major surgery to get to them. Air control systems could be anything from a 'sticky' valve to a faulty sensor.

P0325 = Knock sensor (KS) 1, bank 1 - circuit malfunction
P0335 = Crankshaft position (CKP) sensor - circuit malfunction
P0505 = Idle Air Control System

Hi there have you checked the vitals fuel, spark and compression . these cars are known to have problems with coils .swop the good coil with faulty cylinders , check fuel injector wires for ground and power continuity . if all good the problem should be compression fault should be valves or lifters not seating well

U hav a bad egr valve..causin a vacuum leak. The gasket where its secured cud b at issue tu

First the problem which you mentioned with your car is not new,this problem is noticed by many other nissan liberty cars.
Its a common issue:
i already came through.the car was not changing gear ,it only run in a speed of 20 km.the sensor was replaced and its okay again.now the car has a broken chain and now it requires new gear box.

when the car is engage in park can you shift to R nuetral or drive or its stuck on park.

It can be the issue with transmission or
It can be faulty valve body.

One of our customer with similar problem. This type Nissan uses special CT AFT oil. So if you use ordinary AFT oil it will not respond.
This vehicle has a chain that when broken down like what his did, you hate the car for good, nonetheless buy an almera gear box and replace your cars faulty gear box you will love this car for ever.

HI the fuel pump is situated in the tank beneath the rear seat , sealed by a cover plate retained by a few screws . This motor has 4 ignition coils above each spark plug, one or more could be faulty (common fault ) .To test allow engine to idle unplug one ignition coil at a time this should create a surge on the motor or a misfire , which is normal (no misfire or surge shows faulty coil. Be advised to fit new spark plugs .

run the fault codes and look for cam/crank position sensors.
faulty or loose connections may cause this fault. If you have more than 1 key in the ignition then it has been known that the mass of swinging keys will switch off the ignition
(current recall on all GMC ignition switches for just this reason)

Mine just failed emissions test garage said its burning oil what is the soulution

yes the alternator can send dirty ..too high...or too low a voltage to the system causing all sorts of gremlins.. test test
