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: Ford Windstar 1996 Trouble Codes P0171, P0141, P0161, and P0174

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

We have a 99 ford ranger 3.0L flex fuel and it is throwing system too lean bank 1 & bank 2 codes, P0171, P0174...we have replaced 02 sensors, mass air flow sensor and have paid for 2 diagnostic tests...


Your paid people have never diagnosed ,the lean condition you have.

If it points to MAF Sensor,new or old,why did they stop
testing. Don't have a Data Base they subscribe to?
Don't have that kind of diagnostic experience?

Need to see the system on paper, and follow a trouble
chart or use common sense.

In the end, all you probably have, is a vacuum leak somewhere

Fault code p0174 what is the usually problem with this code


P0174 is System Too Lean Bank 'B'. This will almost certainly be an air leak somewhere in Bank B from where the inlet manifold splits into 2 to feed Bank 'A' and 'B', or possibly a leak in the exhaust manifold / catalyst or where the O2 sensors are fitted into the exhaust. Cleaning the MAF is unlikely to make a difference, as if this is the problem you'll either get a lean code for both banks (P0171 and P0174) or a MAF sensor code (P0101). If the O2 sensor is a fault you'll get an O2 sensor code for Bank B, so don't chance an expensive change of this!
A blocked fuel filter won't only give this code (again it'll affect both banks), ditto the air filter.

As regards to only showing up on highway driving, the leak may only be small and only evident at a higher under bonnet temperature.

I failed the emisson's test. I have a 97 Nissan


P0136 indicates a bad O2 sensor. This reports poor emission performance back to the car's PCM (computer)
P0325 indicates a bad "Knock" sensor which would adversely effect drivability as far as performance is concerned. Only way to fix these 2 problems is replacement of the 2 components.

How do I test and change a bad ignition coil in a 99 Maxima?


Im having the same issue w/ my 99 maxima. had the problem 2 months ago, they replaced coil, changed plugs, told me that I would still get knock sensor code but dont worry about it. Now the rough idling and check light flashing is happening again.

Car trimbles and is letting off fumes


Check all the emmission system components. Make sure there are no unplugged vacuum hoses, or leaking hoses, cracked hoses, brittle hoses etc. If the exhaust makes you eyse smart, it is an indication of extremely high hydrocarbon content, and it wont pass emmission. Check the timing too. An over advanced timing not only damage engine but it also make the engine produce high content of hydrocarbon. A retarded timing will burn cleaner but it makes the engine run slugish, and will make it overheat. Plus it waste gas. Check the distributor, check the ignition coil, have the ignition module tested. check the coolant temp sensor as well. One way to check the cts(coolant temp sensor) is to take it off. You need a multimeter. Heat up some water. Check the resistance of the sensor as the you heat up the water, the resistance should decrease as the water heats up. I cant give you instruction on testing an ignition module because it is a very complicated proceedure and require knowledge in electronics, but some auto parts can test them for free. You can visually check the ignition coil for cracks and all that. Also check for any loose electrical connection.

Diagnostic Codes p0171 bank 1, and p0174 bank 2 (too lean)


Those codes are for the oxygen sensors, lean fuel mixture on both banks. Change them, problem with stalling and rough idle should go away.
