SOURCE: check engine light on
Generally when these codes appear it is due to insufficient fuel pressure. Test your fuel pump to ensure it is within specs. Have you changed your fuel filter?

if u have one oxygen sensor then u need to take a deep look at the bottom of ur car it will be somewhere at the Exhaust pipe if u have a catalytic converter then u will have two oxygen sensors one before the catalytic converter & the other will be after the catalytic converter. Note: the catalytic converter is located at after a little bit of beginning in Exhaust pipe.

What was the code? lean mixture? If so make sure there is no leak in the exhaust. I have worked on a lexus suv, but it was an 89. It had a lean mixture code. After examination I noticed a exhaust leak which was not apparent at first, there is a section in the exhaust the is very thin, and prone to leakage, causing the lean mixture code.

SOURCE: bank 1 too lean
ALL CARS fixes are guessing and hoping at best. 1st thing is it a 4 cylinder or a v6. if its a v6 and you have bank 1 lean but NOT bank 2 lean, then you are probably looking for a vacuum leak affecting only bank 1. Stuck injector will NOT ause this code without also setting a misfire code. Cars use fuel trim. Basically you have BASE FUEL which is the preprogrammed best fuel amount for each condition. FUEL TRIM is the result of when the o2 sensor analyzes how rich or lean the car was, then adjusts the fuel trim to compensate as needed. Most cars set a trouble code around +/-25% fuel trim. You really need look at datastream on a scantool and determine if BANK 2 is also lean and just not quite at code level (IE - Bank 1 is at 25% and set a code, Bank 2 is at 22% and did not). In this case, tream it as a problem that affects ALL CYLINDERS instead of a bank.
Now that the bank thing is settled, lets presume you have a 4 cylinder. As said before, vacuum leaks are a common cause and should be checked early on. There are many ways to do this, but the cheapest and easiest is open the hood and listen for the air whistling/sucking sound and follow it. Doesnt always work, but you may get lucky.

bank one sensor 1 is the bank of cylinders that number 1 spark plug is located in, bank 2 the other side, this assumes u have a V8, the sensor one location is the sensors that are BEFORE THE CATALYTIC CONVERTER, the sensors referred to as sensor 2 are after the ones AFTER THE CATALYTIC CONVERTER IN THE EXHAUST SYSTEM.
