How do I change brake light bulb on 2005 Nissan Altima

Just wanted to know how to replace brakelight bulb on my 2005 nissan altima.

  • Most Helpful of 6 Answers

The first objective is to figure out which bulb you need. I had to replace the bulb for the largest light which was a Sylvania 3157. The next objective is to remove the dang plastic carpet holder/net clip. Recognize that it is a two part piece. Use a flathead screwdriver for leverage. Pry the cap off by levering the screwdriver in the slot on the holder. Then go behind the carpet and pinch the plastic pin still holding the holder in place. Next,pry off the while plastic pieces from the two bolt/nuts you'll need to remove (see manual). Remove the nuts and give the two screws a push from the inside so you can see how the whole light casing comes off. Pry it off from the outside. On the backside of the bulb holder, turn bulb base counterclockwise and gently remove. Pull bulb upward and replace. Do not touch glass on new bulb with your fingers (wear non-powdered rubber gloves). Make sure the bulb snaps in place. Follow these instructions in reverse. Smile, you just learned something new and saved yourself some easy money.

tengo codigo P1574 nesito solucion

tengo codigo P1574 nesito solucion y diagrama

Posted by on

Answer

  • Most Helpful of 1 Answers

Intente traducirlo, acabo de ver en el manual de servicio y esto es lo que encontré; P1574 es el sensor de velocidad del vehículo ASCD por lo que sería en relación con su problema del velocímetro.

Posibles causas:
* Arnés o conectores (La línea de comunicación CAN está abierta o en cortocircuito.)
* Arnés o conectores (El circuito metros combinación está abierto o en cortocircuito.)
* TCM
* Combinación metros
* Sensor de Velocidad
* ECM

Pareciera mas una falla electrica. Espero que esto le ayude a resolverlo; gracias por usar Fixya.

ASCD = Automatic Speed Sensor Control Device
CAN = Controller Area Network
TCM = Transmission Control Module
ECM = Engine Control Module

Este sensor le manda una señal a la computadora y la computadora determina la velocidad la cual hace que se refleje en tu marcamillas. cuando sale este codigo debes chequear:
1. Que la rabiza del sensor no este derretida o dañada
2. que no tenga un corto en los cables
3. que el sensor este funcionando

La computadora utiliza esta informacion de este sensor para muchas cosas. Determina por las millas cuando tu transmicion debe cambiar de cambio, ademas si registra un cambio subito en millas como cuando por ejemplo frenas de cantazo, esta activa el anti lock brake system y otras cosas adicionales.

Este sensor se encuentra en la transmicion por la parte de atras de la misma. Le desconectas el "plug" de la rabiza y verificas lo que te mencione arriba. Para verificar si esta el sensor malo:
1. Sacar el sensor( un solo tornillo 12mm)
2. cosigues un voltimetro
3. pones el voltimetro en AC( Voltaje AC)
4. le conectas los dos cables del voltimetro a los dos terminales del sensor
5. le das vuelta al sensor y debe dar .05 volt, si no da lectura reemplaza el sensor con uno nuevo.

TSB Bulletin:
Vehicle Application: 2003 Nissan Altima 3.5L, Eng Cfg V6, Eng Des VQ35DE
Customer Concern: The check engine light is on with codes P1574 and P0720.
Tests/Procedures: Locate the A/T Revolution sensor and the A/T Turbine Revolution sensor on the back end of the transmission. Both connectors are Black in color, and if swapped, will cause the codes to set and the transmission may not up shift. The A/T revolution sensor is the one closer to the end of the transmission (on the end of the case). The correct wire colors on the A/T revolution sensor are Red/Yellow, White and Black. The correct color wires at the A/T turbine revolution sensor are Red/Yellow, Green and Black.
Potential Causes: Improperly Installed Automatic Transmission Connector - Swapped connectors on the automatic transmission.
Defective Automatic Transmission Revolution Speed Sensor
Diagnostic Codes: P0720, P1574

Procedure and location:
Disconnect electrical connector.
Remove revolution sensor from A/T.
Reinstall any part removed.

An engine speed sensor is mounted on the vehicle’s crankshaft and is usually where the speedometer gets its data, whereas wheel speed sensors are located individually at each wheel or axle generating a signal that changes with wheel speed.
It is important that these two speed sensors are always in good working condition to provide accurate data. If one of them gives the wrong signal, control functions of the engine ECU and ABS ECU will be largely compromised. So to have a long-lasting speed sensor, cleaning it every now and then is necessary. Simply wipe off the grime it has accumulated with a towel. Or it’s okay to carefully blow-dry it with compressed air. Anyway, it does not need to be hospital-clean, it just needs to be free from major debris and metal media.
If this didn't do it for you call autozone and they can pull up pictures of it for you and it will show the location to the exact positioning.
Hope This Helps

How to change fuel pump on 2005 Nissan Altima?

It will turn over but will not start. On the second or third time, it will start. At first, it would start and then cut off after driving about 100 yards. I put some fuel injector cleaner in the tank. But, I don't know if it helped or not. It doesn't cut off anymore, but I'm still having the same problem with starting. I don't know if this will help, but if I turn the key in the ignition half way and hold a few seconds, the car will start. What are your thoughts and can anyone replace the fuel pump? What is the procedure...step by step? Thanks so much in advance.

BEFORE YOU TRY TO START YOUR CAR, TURN THE KEY TO THE ON POSITION AND STOP TO HEAR A WHISSING SOUND COMING FROM YOUR FUEL TANK. IF YOU HEAR THAT NOISE, THAT IS YOUR FUEL PUMP ENGAGING AND IT IS WORKING FINE. IF NOT, YOU SHOULD DEFINITELY GET IT CHANGED. ITS A GRUELING PROCESS SO HAVE A MECHANIC DO IT. IF YOUR FUEL PUMP IS WORKING, TRYING CHECKING THE PRESSURE OF YOUR FUEL. YOU MIGHT NEED A NEW FUEL FILTER(IT CAN GET CLOGGED UP) OR YOUR FUEL PRESSURE REGULATOR MAY BE MALFUNCTIONING.

nissan altima starting problem

Hi

I have a 2005 Altima 2.5S.(42k miles) I've had the car for 2 years and not had any problems. However for the last 2 days, its not starting properly on the first try. In some cases I have to let the car sit for 40 minutes before getting it to start up. The battery is brand new. The engine cranks over without any hesitation.

I've tried starting holding the peddle down 2/3 down (as suggested on some forums) - no luck
I've removed the battery terminal (in hopes it resets something) - no luck.

I connected an ODB II scanner and I get "Camshaft Sensor - Malfunction on Circuit 1" (Cen-Tech error code P0340)

I see there is a recall to reprogram the ECM - would this fix the problem. Or should I change the sensor?

Thanks

i think replacing the sensor is in order. i know all car makes have "recalibration updates" for the ecm and should be done, but have rarely fixed vehicles on just that alone. and your symptoms suggest the sensor could be intermittently bad

The oil filter is located behind the right (passenger) inner fender cover. It is right next to the crankshaft pulley at the bottom of the front of the engine facing toward the right front wheel. I do not have a picture at this time.

Hope this is helpful!

timing chain noise on nissan altima 2005

timing chain noise on nissan altima 2005 change oil for syntetic 5 w 30 and it got worse before did it only when cold now is doing it at all the times

Posted by on

Answer

  • Most Helpful of 2 Answers

The timing chaing noise is very common on almost all v6 nissan engines. There is a significant difference for the maxima's though.

Timing chain noise is very common and it is the result of the secondary timing chain tensioners. They often stick and put too much tension on the chain and the plastic guides for the tensioner wear down to metal and that is the noise you hear.

At Nissan, I have performed this replacement many times and I suggest you take it to the dealership to have it fixed.
