Question about 2001 Nissan Maxima

Open Question

Getting P0159 code on Nissan Maxima 2001. Replaced the o2 sensor. Erased codes, reset computer. Have driven for about 160 miles over two days. Checked for code and it was still there. What to do? I need to pass the smog test (CA). The check engine light is "not" on. Possible it's burned out too.

The best way is to use a scan tool to clear the codes, that will turn off the light, also disconnecting the battery over night may work, but no completely sure about that, it varies from year to year.

SOURCE: location of a o2 sensor 2001 nissan maxima

bank 1 refers to the side of the engine that #1 cylinder is on , and sensor 2 refers to downstream , after the catalytic converter. , this link shows bank 1 on a 2001 nissan maxima V6 being on the firewall side . if you had a 4 cylinder it would be downstream after the catalytic converter .

catalytic converter is the way to fix your problem because they do an emissions test and the code want go away even if you get the light off before you take it in they will no the computer has just been reset so which means all the sensors want have enough info to give the computer because of being reset sorry to break it to you.

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):

And here additional details: DTC P1147 O2 Sensor

Nissan maxima code P0325,P0100 and P0110


Well, sometimes you get lucky replacing parts, but usually its something other than the component in question.
The trouble codes are a guide as to what to test, not what to replace.
Code 325 is for the knock sensor which could be a phantom code.
Code 100 is for a bad signal from the MAF sensor which may or may not be caused by a bad sensor. It could be a vac leak too.
Code 110 is for a bad signal from the intake air temp sensor. The signal tells the computer what the temp of incoming air is to help the computer decide how rich the fuel mixture should be.
You need to get the testing procedures for each code and follow them. I would skip code 325 and start with code 110.
The fuel pump was probably a waste of money unless you checked fuel pressure before you replaced it and it was low. Same thing with the O2 sensors. Very rare if both sensors fail at the same time.

2001 nissan maxima engine misfire


The Fuel Pump, I assume failed & was another issue

The Fuel filter is changed every 3 years, as preventative
maintenance

The Codes for the most part are O2 Sensors, that are over six
or seven years old & over 100,000 miles & should be replaced
as preventative maint or if they fail ,sooner

You don't throw out any what if senerios, or replace any parts
in an effort to resolve anything

You component test & replace only failed parts, related to the codes
& system that has a fault & drivability symptom

You should know if the spark plugs are over 3 years old

Clean the MAF Sensor & check for vacuum leaks on the entire car

I replaced o2 bank 1 sensor and still getting p1148 closed circut 02 bank 1 code


Im curious if you had code erased after replacing the sensor? Simply by replacing the sensor will not reset the computer. You must have someone (Autozone) to check it and reset the computer. This takes a matter of seconds to a minute to hook a handheld comp. called an OBD2 into the vehicle under the dash. It will read the code and display the code, Then have them erase the code to see if it reappears.

It's an o2 sensor code. So you more than likley have burnt wires associated with that o2 sensor.
P1133 = O2 Sensor Fault - Insufficient activity (Bank 1 , Sensor 1)You remove the negative battery connection from the negative battery terminal for 10 minutes.

You ALWAYS reset your computer when you do sensor swaps, when fixed erase code, and see if it stays out. your pcm is getting the wrong info from sensor. good-day !

Need to reset computer on my 2001 nissan maxima


you can try unplugging the battery for few days. not guaranteed that it will do, but you can try it. if not, than you can get just a simple code reader from sears for about 75bucks and do it like that and after that you have a code reader for the future. if you dont want to do that, then you need to go to nissan dealer, pay 45 bucks (half hour of labor??) depending on a dealer and have the light/ecm memory erased and not have a code reader for future issues. I would buy code reader and erase my self and keep code reader.

o2 sensor, and computer? Try running in to one of the bigger auto parts stores, and they will usually scan for codes free of charge. Then get back to us with that code or codes, before you go spending that kind of money.

Possible mass airflow sensor. A cheaper way to get around paying for the super expensive 2001 Path part is to use the same year maxima sensor since they use the same motor :)

P0159 is what the read out tells me. Just what do I need to do about this? I turned off the 'Check Engine Light' and it's still off after 2 days. But......!!!


What does that mean? This involves the rear oxygen sensor on the passenger side. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Symptoms You will likely not notice any drivability problems, although there may be symptoms.
Causes A code P0159 may mean that one or more of the following has happened:
  • The oxygen sensor is faulty
  • The wiring to the sensor is broken / frayed
  • There is an exhaust leak
Possible Solutions The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the rear passenger side oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
  • Check and fix any exhaust leaks
  • Check for wiring problems (shorted, frayed wires)
  • Check the frequency and amplitude of the oxygen sensor (advanced)
  • Check for a deteriorating / contaminated oxygen sensor, replace if necessary
  • Check for inlet air leaks
  • Check the MAF sensor for proper operation
