Top 10 2002 Nissan Maxima Questions & Answers

i have Nissan Primera s manual,03 reg. Battery went dead two days ago, today i tried to open the car with my remote key, it didn't respond as battery was totally dead. I tried to open the door manually with the key,it wont open. Can any one help me please.....?

You can wait its just fine, However if you ever start to notice oil leaking from front cover, then you will need to change. If there is no loss in power feel sluggish especially on take off, Its almost impossible for these type of chains to break. So enjoy until the wheel fall off..lol. good luck

only 4 bolts hold the seat in they may have a plastic cover on them that can be popped off with a screwdriver.remove the bolts and lean the seat back check the wires going to the motor and make sure it has power going to it.Don't know of any way to manually recline the seat without taking it apart.

Nissan Car 350Z & Maxima 1999-06 Radiator - Removal & Installation

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Drain the cooling system.
3. Remove or disconnect the following:
   Negative battery cable Coolant reservoir tank and bracket Upper mounting bracket Upper radiator hose Oil cooler lines, if equipped Lower radiator hose Cooling fan and condenser fan Fan motors and shields Radiator

To install:

1. Install or connect the following:
   Radiator Fan motors and shields Cooling and condenser fans and torque the bolts to 44 inch lbs. (5 Nm) Lower radiator hose Oil cooler lines, if equipped Upper radiator hose Upper mounting bracket Coolant reservoir tank and bracket and torque the bolt to 44 inch lbs. (5 Nm) Negative battery cable
2. Fill the cooling system to the proper level.
3. Start the vehicle, check for leaks and repair if necessary.

WARNING Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

1. Before servicing the vehicle, refer to the Precautions section.
2. Drain the cooling system.
3. Remove or disconnect the following:
   Negative battery cable Coolant reservoir tank and bracket Upper mounting bracket Upper radiator hose Oil cooler lines, if equipped Lower radiator hose Cooling fan and condenser fan Fan motors and shields Radiator

1. Before servicing the vehicle, refer to the Precautions section.
2. Drain the cooling system.
3. Remove or disconnect the following:
   CAUTION Do not damage or scratch the A/C condenser and radiator core while removing.
   CAUTION Because A/C condenser is onto the front-lower portion of radiator, moving to rear direction should be at minimum.
   Negative battery cable Engine cover Air duct and air cleaner case assembly Bracket mounting bolt for anchoring A/C piping Reservoir tank and bracket Upper and lower radiator hoses Radiator cooling fan assembly On A/T models, A/T fluid cooler hoses. Plug hoses to avoid leakage Cover, then two A/C condensing mounting bolts located in the upper part of the radiator Rotate two radiator upper mount brackets 90 degrees in the direction shown in the illustration and remove

4. Remove the radiator by performing the following:
   CAUTION Lifting A/C condenser should be minimum to prevent a load to A/C piping.
   With lifting and pulling radiator in a rear direction, disassemble lower mount from radiator core support center. Lift A/C condenser up and remove radiator after disengaging the fitting as front-bottom surface After removing radiator, put A/C condenser on radiator core support center to prevent a load to A/C piping, and temporarily fix it with rope or similar means

To install:

1. To install, reverse removal procedure.
2. Check radiator cap for any leaks.
3. Start and warm up engine. Check for engine coolant leaks and A/T fluid leaks.

Hope this help (remember comment and rated this).

About DTC P1800, I suggest check the harness and verify it is plugged in and still functioning. Also, try checking your vac tubes to verify that they are not reversed. Also read this TSB with details about correct diagnostic: DTC P1800 VIAS CONTROL SOLENOID VALVE

The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.

DTC detecting condition:
• An excessively low or high voltage signal is sent to ECM through the valve
Possible cause:
• Harness or connectors (The solenoid valve circuit is open or shorted.)
• VIAS control solenoid valve

Will need replaced the solenoid valve (P/N - 149558J10A). The valve is located under the engine cover. It's a Nissan only part so you have to order from the dealer, either online or in person. It's cheaper online. Check this sample Nissan engine location (click image for zoom)...





DTC P1147 - Bank1 Sensor 2 O2 sensor maximum voltage monitoring
Component Description: The heated oxygen sensor 2, after three way catalyst, monitors the oxygen level in the exhaust gas on each bank.

Even if switching characteristics of the heated oxygen sensor 1 are shifted, the air fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2.

This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Under normal conditions the heated oxygen sensor 2 is not used for engine control operation.

DTC detecting condition: The maximum voltage from the sensor is not reached to the specified voltage.

Possible cause:
Harness or connectors (The sensor circuit is open or shorted)
Heated oxygen sensor 2
Fuel pressure
Injectors

Majority of cases this is either a faulty O2 sensor, or short/open in wiring harness. Bank1 sensor2 is the rear O2 sensor on the passenger (right) hand side (click image for zoom):



Here is simple test with voltmeter to test O2 sensor. If it fails test, replace sensor. If not, then you will have to start tracing the wiring harness for a short/open in it (click for zoom):

P0720 - Vehicle output speed sensor .
And
P1574 - Auto speed control device speed sensor.---------------- ------------------ P 0720 - Output shaft speed sensor circuit
---------
P 1574 - ASCD speed sensor out of range (the car has two speed sensors, one on the transmission and another on the "unified meter and A/C amp". If they read differently, it generates this code.
----------- P0720 code is the Speed Sensor. It is located on the driver side end of the transmission. It is easy to replace approx $100 on rockauto.com and $140 at the dealer. Take of the drivers side front wheel and the plastic guard and it is visible just forward of the axle on the top of the transmission.----------------

The P0720 code is for the Vehicle Speed Sensor (output rev. counter). It's located low down at the driver's side end of the ******. It's NOT the "other" one at the top of the Gen. 5 "bellhousing".---------------

This will help.Thanks.Helpmech.

This is hard to say with hearing the noise but try to pin point the noise , is it coming from the top or bottom of the motor , the knocking noise could be a bearing in the lower motor or may be something else making it sound like a bearing,
