Thanks again guys! I will dig around and see what up. I'm not good in wiring (although i love it) but i will give it a try and look around for the brain. it does work which i what i like. i wont remove it. I repeat "all i wanna know is how to arm it on demand". it just does it randomly and when it does all i do i press the button and off we go!

is this same button! when i trun off the truck it rapidly flashes for a couple of seconds thats it. when it activates itself it flashes rapidly until i press it and turn the truck on.

cool guys thanks! but all i wanted to know its how to arm it its arms itself randomly i wanna gain control!

2001 owners manual

ima get some in a few hours! also pictures of the manual(01) sup[porting the immobilizer.

well, now that you mention "chip in key" makes me wonder. i start my truck every time with no problem. I have an LED light under the SECURITY light that flashes rapidly when its activated. when that happens i just push the button to start it again. but i wanna know if some one has the same device. and if so how do they activate it?

NO! Its basically a starter kill switch. when its enable(activated) it doesn't let the engine crank.

I have an Immobilizer device on my truck. It could be OEM because it says on the manual. It sometimes enables itself and i've tried to enable it but i have failed. So anyways, i would really love to have it enabled at night. does anyone have one, and/or knows how to enable it?

thanks a lot! i will do the basic tune up first since winter is around the corner. then i will ask my uncle to check the injectors etc. money is a little tight right now! thanks again!

ok so i did a little research and here's what i have found so far. From the FSM, P0300 causes include: - Improper spark plug - Insufficient compression - Incorrect fuel pressure - The injector circuit is open or shorted - Injectors - Intake air leak - The ignition secondary circuit is open or shorted - Lack of fuel - Drive plate or flywheel - Heated oxygen sensor 1 (front) ---------------------------------------------------------------------------------------------------------------------------------------------------------------- A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why. A code P0300 may mean that one or more of the following has happened: * Faulty spark plugs or wires * Faulty coil (pack) * Faulty oxygen sensor(s) * Faulty fuel injector(s) * Burned exhaust valve * Faulty catalytic converter(s) * Stuck/blocked EGR valve / passages * Faulty camshaft position sensor * Defective computer Possible Solutions If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors. Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open. ---------------------------------------------------------------------------------------------------------------------------------------------------------------- Nissan Technical Service Bulletin #NTB02-006 addresses the following codes for 2001 Pathfinders: ^ P0138 ^ P0139 ^ P0140 ^ P0158 ^ P0159 ^ P0160 The bulletin states that if you have any of the codes, replace the incident O2 sensor. If you have codes P0138, P0139 or P0140, replace the rear RH O2 sensor with the following part, based on pro date: Built up to 8/1/00: P/N: 226A0-4W001 Built on 8/2/00 or later: P/N: 226A0-4W010 The TSB also has you check the ECM part number and compare to a list of ECM part numbers on the bulletin, which will require the use of a CONSULT II scantool (meaning a trip to your Nissan dealer. Depending on the ECM program currently installed in your vehicle, it may need to be updated to the latest program revision. Rear O2 sensors are for testing catalytic converter efficiency and have no affect on drivability, unlike the front O2 sensors, which the ECM uses to help provide the proper air/fuel ratio. As far as O2 sensor identification, "Bank 1" is the engine bank that starts with #1 cylinder. "Sensor 1" is the front or "upstream" sensor. "Sensor 2" is the rear or "downstream" sensor. Bank 1 on the VQ engine is the right side bank and Bank 2 is the left side bank. hopefully some can help me understand this a little bit more. any help is greatly appreciated.

well i just found this code chart! http://forums.nicoclub.com/obd-ii-code-chart-t244617.html According to the chart code P0138: O2 Sensor Circuit High Voltage (Bank 1 Sensor 2) and code P0300: Random/Multiple Cylinder Misfire Detected. Im not really good at car mechanics. what does P0138 refers to, is it the o2 sensor itself? or a just a sensor? and on P0300 what cylinder does it refer to? like a brake master cylinder? sorry i only have basic knowledge! EDIT: and if i replace lets say bankd 1 sensor 2 will that clear that code? or is it something else that causing the problem?

thanks for the reply! it reads 125,xxx! i was thinking the same thing. im also thinking of doing the complete tune up!

im just wondering if anyone else had this same issue with their truck. if so, can someone give me some advise. the guy at autozone said to use injector cleaner(lucas) fill the whole tank and drop in two lucas bottles. wait and see if the light stays on for a week to go get it checked at a mechanic. i was on the highway and the light came on. had it checked at autozone and it got two codes. 1) P0300: random cylinder misfire detected. probable cause 1)ignition system fault. 2)fuel system fault. 3)large vacuum leak. 4)MAF sensor fault. 5)AF/H02S (air-fuel/heated oxygen sensor) 2) P0138: heated oxygen sensor - bank 1 sensor 2 (H02S12) circuit high voltage. probable cause 1)open or short circuit condition. 2)high fuel pressure or leaking injector. 3)faulty heated oxygen sensor - bank 1 sensor 2 (H02S12) thanks for reading! i hope some can help me!

Thank you very much! I will definitely get then straight today! I jus wanna be able to see the road crearly and not blind oncoming traffic! Thanks again!

Hello guys im a newbie! even though im ojn my phone, i did searched for headlight adjustment and found nothing. I looked and looked at the headlite for the adjustment screw and nothing. can anyone tell me how to adjust them? or could it b the bulb itself?

Hey guys! I figured it out now! Turns put that the transfer case was in 2H.....dounw was 4H.....i was moving itn between those two. So to move it lower i have to press down. But if i put it N it wont move all. After moving it for time...it grinds!

I still cant memorize the gears on the tranfer case. There are two gears above N and one below N. I can shift down fromN just fine. But above N its imposible.

I really appreciate your help! Thabks alot! On another topic, im having trouble shifting the transfer case up to (4l and 4h i think) is it supposed to be like that? I mean i dont really need it right now. Maybe when the snow falls hard i might want to try

I dont know about the bearings. the pathy has 124456 miles. Thanks for the response!

the rotors and pads are from WAGNER. sorry i posted again im on my phone and have limited space. P.S. R50 is automatic

Hello my name is Alex im 21 in two days i turn 22. Im originally from Mexico but i live in Chicago. I just bought a 1999 pathfinder LE canadian model for 4000$. I NEED FRONT PADS AND ROTORS i got a quote for 239$ parts and labor is that a good price 2pay
