2006 Nissan Xterra - Answered Questions & Fixed issues

Hit a kerb? Tyre pressures incorrect? Broken wishbone? Etc etc etc.

You are going to do a few tests before we can say a starter failed. First do you hear a loud click in start position? If not go to starter and test for power. Large post should always have power. Small wire should have power in start position . If no power to small wire ,you're going upstream to neutral safety switch and ign switch. If it's getting power in start position, have someone hold in start position and tap on starter with a hammer. If it starts replace starter. If still no startcheck battery,ground cable for failure

Put original key close to ignition switch

Do you have enough motor oil in the motor if you do you may have a bad oil pump , but before you change the oil pump check the oil pump strainer in the base pan I hope this information helps you

Why are you Replacing the Ignition Immobilizer Module ? how do you know it needs too be replaced ?

Nothing you can do , except make it worst . All vehicles from 2000 on have a transponder chip inside the key head . You need a factory or some other professional type scan tool to read codes in the theft - deterrent module . You can't guess an fix the problem . You can buy a launch scan tool for about $800.00 that would work. You need to know the code stored . https://www.aa1car.com/library/troubleshoot_antitheft_system.htm NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS) PFP:25386 Description UBS00MOP ?

Check what other vehicles use that engine then Google again

check if the silicon was correctly applied and if no water parth ways have been blocked or try using VECTORREINS SILICON

Check that your brake lights work as the brake light switch sends a signal to release the shifter lock solenoid .

Have your temperature sending unit/sensor checked for proper operation, it may not be working and not placing the engine into cold start mode so it will start easily. This is like the old style automatic choke that's stuck open.

It could be your thermostat inside your radiator hose. They are a common thing to fail, but luckily relatively cheap and easy to DIY with some automotive background.

Thermostats usually work with a spring that allow them to have a closed "door" while your car is still cold working its way to optimum operating temperature. (Usually around 200°F depending on vehicle. You can check with a parts store for your thermostats rating) Once hot the thermostat opens to keep the engine from continuing to get hotter to the point of overheating.
When a therm. gets stuck in the open then your vehicle will usually not allow cabin heat in efforts of keeping emissions down. Cold running engines produce more hydrocarbons = not environmentally friendly.
This could also trigger a code that could set your check engine light. Before you go changing anything you should stop at an auto part shop where they can check what codes are stored for free. Codes aren't black and white though so do some research after as well.

A bad thermostat would set codes such as

•P1221
•P0128

Where is the fuel filter on a 2006 Nissan xterra?

Does your car overheat too? If so, you could have a faulty thermostat, an air pocket in your cooling system or maybe even a leak somewhere. My truck's heat would only work while I was driving, then stopped working altogether while the engine started to overheat. I changed the thermostat, then the heat would blow hot/cold/hot/cold, I didn't realize you had to bleed the air out of the system after changing the thermostat. I did that and now the heater and engine run great.

If you have never taken out a valve body and computer control system inside the transmission, I suggest you don't. Parts fall out. You could end up with a transmission that doesn't work.

If you have drive by wire (electronic throttle body) your TPS is under the gas pedal. Check the connection/plug for corrosion.

I usually have someone hold a 1/2" breaker bar on with their foot while I jump on the end of the bar. Scary but it works.

Disconnect the negative cable first and then the positive cable and remove the battery. The lights/alarm will go out when battery is disconnected and may come back on when reconnected. Use door lock key fob to shut alarm/lights off if they come back on when battery is reconnected

Hi Gabriel if you can find a good garage with a good diagnostic suite. If not its s job for the main dealer. Regards Zjim...

There is only one brake switch. The other at the brake pedal is for cruise control. You will have to access the shift solenoid and check for power and ground at the solenoid when the brake switch is activated. If power and ground ok, I would suspect shift lock solenoid. Usually if brake switch is the problem the brake lights may not work
