How fixed p 1148 nissan armada 2008


It may be a faulty oxygen sensor.
For Models 2005 and up:
- Faulty Air Fuel Ratio Sensor 1 Bank 1
- Air Fuel Ratio Sensor 1 Bank 1 circuit is open or shorted
- Air Fuel Ratio Sensor 1 Bank 1 circuit electrical connection

Before you rush off to buy replacement parts it's worth giving a mobile mechanic a call. Those guys are usually very good and far cheaper than a dealership. And a second opinion is worth paying for.

Air sensor check engine light


Ok as a guess that you have a SUV and you have different air faults. if you are a DYI'er go to an auto parts store and get an error code tool. Harbor freight for $30-50. Hook it to the car and find out which sensor is it calling for. Note, you can reset the check engine light on most tools that are not the cheapest.

I got an P0171 code on my 2000 Lexus which I'm told has something to do with my mass air flow sensor..Is this a commmon problem and what symtoms can it cause?..Car is slow to accelerate and is idiling on...


P0171 sets when air/fuel ratio feedback is stable after engine warm up, & fuel trim is considerably in error on the lean side.
The signal from a/f ratio sensor is approximately proportional to existing air-fuel ratio.
CHECK: system for intake leaks, incorrect fuel pressure, plugged fuel injectors, 02 sensors or coolant sensor operation.
check air fuel ratio sensors. to test main AFR sensors directly you will need a good scan-tool to test parameters.
A thorough preliminary check is important. If you take your time you may find the answer before you start playing the "process of elimination " game.
Good luck, let me know how it is going.

The car doesn't have power when hit the gas pedal speed pick up really slow also have code of 171 sistem too lean on bank one,lexus 2000 rx 300


this code sets when air fuel ratio feedback is stable after engine warm up,and fuel trim is considerably in error on lean side;The signal from air fuel ratio sensor is approximatelyproportional to existing air-fuel ratio.

for this code suspect excessive lean condition,normal rangefor total trim is between -35% to +35%,DTC uses "two-trip detection Logic".

Check system for intake leaks,incorrect fuel pressure,plugged fuel injectors,O2 sensor or coolant sensor operation.

check air-fuel ratio sensors
to do it you need to check them with a good scanner tool.

also,check MAF sensor operation.

personally i would clean with the special spray for MAF sensor (you can get it from you autoparts store) and try a fuel injector cleaner before start spending money in shops.

hope this info can help you.

The air fuel ratio sensor is located in the exhaust manifold before the convertor. It looks like a o2 sensor.
