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 .

SOURCE: CRANK SHAFT POSITION SENSOR 20002 NISSAN ALTIMA

1st, Nissan had a recall on Crank position sensors for 2002-2006 Altima's. Check with you dealer before you go doing any repairs. You may discover you can get your car repaired at no charge.
NHTSA Campaign ID number :O7V527000
Symptom: Erratic behavior. Stalling and no starts and very difficult to diagnose due to the time frame in which the component actually malfunctions. The warranty should not be limited to the original owner.
I would also need more specifics as to which engine you have so I might assist you in where the location of the sensor is. The Altima had a 4 and a 6 cyl engine offered that year.

SOURCE: 1997 Nissan Altima with idle jump

The description sounds like a technical Service Bulletin Nissan came out with on your car. It fits your description to a "T".
However, the codes you are getting are not what the service bulletin reports. The code they say it sets is DTC 0400 which relates to an irregular EGR operation, causing a problem where it will not maintain an idle or Will idle roughly. There is not a recall campaign on this item.

As far as misfire problems: Nissan had a service bulletin out on problem ECM's which caused this problem. Check with your local dealer. This may possibly be covered under warranty.
The reference number is NTB97-026 The bulletin was issued March,12,1997 There was no recall on this item.
Good luck to both of you.

SOURCE: Code: P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1

is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.

if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

I have a 2007 Nissan Altima 2.5 with a "Check Engine" light - a Code of 0171, "System Too Lean". Car engine is revving high, up and down constantly.


code p 0171 refers to system too lean===causes --intake / exhaust leak---AIR system---MAF/VAF sensor fuel pressure ---pump---injectors/s --HO2S sensor
two things stand out
air leak inlet manifold --check for vacuum leaks in vent controls , transmission actuator , brake master cylinder and vacuum hoses
heated oxygen sensor (HO2S) faulty
basically the ECM gets a report from the HO2S and adjusts the air /fuel mixture accordingly so if that unit is faulty or the wiring is faulty then the ECM cannot maintain correct mixture
also the ECM gets reports from the mas air flow ( MAF) or volume air flow) and accordingly also along with the HO2S report adjust the throttle position as well
I would be taking it to an accredited service shop that works on your make of vehicle and discuss the code and the causes with them so that it can be fixed

2003 Nissan Altima 2.5L Service Engine Soon Light is on, Auto Zone says codes are for MAF and O2 Sensors. Car hard to start after driving a while but when starts appears to run smooth. Auto Zone thi


ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........
  • P0103
    Mass Air Flow Sensor Circuit High Input
  • Possible causes
  • Faulty mass air flow sensor
    - Intake air leaks
    - Dirty mass air flow sensor
    - Dirty mass air filter
    - Mass air flow sensor harness is open or shorted
    - Mass air flow sensor circuit poor electrical connection
  • Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
  • possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
    - Engine stall
    - Engine running rough
    - Excessive fuel consumption
    - Excessive smoke
  • the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).

Hello again. I have the 2006 Nissan Altima 2.5S ......ok I had the issue bank 1 sensor 2 heater circuit low P0037 is the code I was getting. But when I connect the code reader it says that the heated 02...


O2 Emission Monitors & Evap Monitor-- are two
different systems

Get ALL your OBD Codes & work them one at a time,
& DO NOT Clear any data with code reader or removing
battery cable, or the monitors ALL have to run again

The heater may work in the sensor, but the sensor doesn't
switch fast enough or is worn out & the front sensors get
replaced at 100,000, before they fail or slow down

The Evap Codes will be needed, to work on that issue
That monitor runs last & only every few days

IF--- you had professional scan tool software, you would see
11 monitors & maybe 8 that run on your vehicle

There will be at least 2 for the O2,one for cylinder misfire,
one for evap, one for egr,& three others

What is p1148


P1148 - Closed Loop Control Function Bank 1
This mean that the closed loop control function for bank 1 does not operate even when vehicle is driving in the specified condition.

The Powertrain Control Module (PCM) or Electronic Control Module(ECM) monitor the function of the Front Oxygen (O2) sensor or Air/Fuel (A/F) sensor by comparing the signal with the Rear O2 sensor.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Harness or connectors Front Oxygen (O2) sensor or Air/Fuel (A/F) sensor 1 circuit is open or shorted.
- Front Oxygen (O2) sensor or Air/Fuel (A/F) sensor bank 1
- Front Oxygen (O2) sensor or Air/Fuel (A/F) sensor bank 1 heater

Possible solution:
- Repair harness or connector. If repair is needed
- Replaced Front Oxygen (O2) sensor or Air/Fuel (A/F) sensor bank 1


Then, possible causes are faulty harness or connectors to the air fuel ratio sensor, a faulty air fuel ratio sensor (1) or faulty air fuel ratio sensor (1) heater. Most likely yes it is just faulty sensor. Just replace this devices and reset the stored codes.

Keep us updated.

The code indicates a problem with Air/Fuel mixture, and it is very possible with the "chips" you installed, the A/F ratio the ECM sees is out of tolerance. As far as inspections is concerned, you may need to remove the chips and reset the ECM before you go for inspection.

Over consumption of fuel


tire psi correct .no dragging brakes,clean air filter.proper gap on spark plugs,clean oil,check engine light off should be good to save and calm driving habits should help/ oxygen sensors/ o2 .should be changed at 100,000 km regardless as they wear out,slow crosscounts to ecm via fuel management ,dont over look o2 sensors just because there is no dtc in computer history
