2001 Nissan Xterra - Answered Questions & Fixed issues
2001 Nissan Xterra Camshaft Position Sensor Location.
the camshaft sensor is located into distribuitor.......The camshaft position sensor is a basic component of the engine control system. It monitors engine speed and piston position. These input signals to the ECMare used to control fuel injection, ignition timing and other functions.
The camshaft position sensor has a rotor plate and a wave-forming circuit. The rotor plate has 360 slits for a 1° (POS) signal and 6 slits for a 120° (REF) signal. The wave-forming circuit consists of Light Emitting Diodes (LED) and photo diodes.
The rotor plate is positioned between the LED and the photo diode. The LED transmits light to the photo diode. As the rotor plate turns, the slits cut the light to generate rough-shaped pulses. These pulses are converted into on-off signals by the wave-forming circuit and sent to the ECM.
The distributor is not repairable and must be replaced as an assembly except distributor cap and rotor head.
NOTE: The rotor screw which secures the distributor rotor head to the distributor shaft must be torqued properly.

Xterra won't start when the battery has juice free of corrosion and starter is freshly installed
Check the cleanliness and tightness of the battery terminals. Loosen, twist and retighten them. Also check the cleanliness and tightness of the black earth cable where it attaches to the engine block/bodywork. A bad earth can cause the symptoms you describe.
A quick check you can do is to connect a jump cable to the battery negative terminal - the earth - and connect the other end of the cable to somewhere suitable on the engine/bodywork.
If the car starts no problem with the jumper cable - it's pointing towards a bad earth/connection somewhere on the battery earth

2001 Nissan xterra temp gauge rises to H when idling?
I'll start with the most common cause.
Check the radiator cooling fan to see if it is functioning correctly.
It is turned on by a sensor that screws into the engine block, and there is also a relay in the under-hood electrical box.
Finally, the electric fan is mounted at the radiator.
There should be 2 fans there, one of them is for engine cooling, one for Air Conditioner cooling.
The engine cooling fan should come on anytime the engine temperature exceeds the setting of the screw-in-the-block sensor.
If it does not, it could be the sensor, the relay, or the cooling fan itself that has failed.
If you live in an area of the country that is prone to extreme cold temperature, "road salt" can contribute to fan failure.
If all these check OK, write us back and tell us, we'll go to step # 2.
God bless your efforts.

My 2001 xterra started making a weird sound between 20 and 35 mph. It sounds like there is a leak in some pressure system.
Common Car Noises and Their Likely Causes
Clicking noise while turning
Starts faint, gradually becomes more noticeable until very loud
Failed outer CV joint (constant velocity joint) due to torn boot (most likely) or old age
Replace either the whole axle assembly (recommended) or the outer CV joint
Water pump noises
Difficult to diagnose because of water pump's location
Noise usually caused by damage to the bearings in failed water pump
Only cure is replacing it. If possible do it at the same time as a timing belt replacement to cut down on labor costs
Squeak or squeal from an engine belt
Loud, high-pitched squeak or squeal
Belts either need adjustment or replacing
If belts only squeak when damp, they probably just need adjustment. If they squeak constantly, they probably need to be replaced
Exhaust heat shield noises
Rattle that you hear when car is idling
Damaged heat shield
Replace heat shield

P0300 is a code that indicates the engine has a random cylinder misfire. The causes of this are so numerous as to not to be able to provide any real help without hands on testing. You also may need the engine control computer flashed, many vehicle makes did updates because this code keep setting and no problem was found to justify it.

Can I by pass the egr on my xterra it does not have the connection on the upper part of the motor
Depends on a lot of things.
1) Does the location of your home have any vehicle inspections that require a state or local inspection?
If so, you are very likely in big trouble.
If not, you might be home free. Maybe.
2) You will need to check with, and make friends with, your local Nissan dealer, to see if the frontier motor had the EGR in another location, so you could still hook it up with longer vacuum lines.
3) By passing the system could at least cause your "Check Engine" light to stay on forever, and at worst, could cause your engine to stop running right, or at all over time, because the computer is set to read the EGR system and adjust the engine to the readings that the EGR tell it to.
4) If all that is missing is that valve, and absolutely nothing else, it might be remotely possible to drill a hold in the upper intake and screw an EGR into it and hook it up, but I wouldn't place any bets on the outcome.
God bless your efforts.
