There are 3 oxygen sensors on your van. Left bank would be the front left. Try replacing it and see if that helps but remember to reset the computer. Where I work the sensor costs a little over $100.00.

Why the check engine light comes on and off runs great


The check engine light is on to tell you the computer has found a problem that will affect performance, gas mileage, or emissions.
Such as the code 171 you asked about.
Code 171 is for the fuel mixture on bank one being too lean. The O2 sensor is telling the computer the fuel mixture is too lean and the computer can not make it rich enough.

I have a 03 ford f150 4.2...It has started spark knocking when under a pull,and gas mileage has gone down


Sounds like you have a timing issue with the truck. Could be your ecu or the sensor(s) that feed data to your ECU.

Ive been having issues with my 2001 tacoma pre runner. The check engine light goes on and off. It read a P0171. I replaced spark plugs and MAF sensor. Light has not come back on again but engine still...


That code is P0171= system too lean (bank 1). The computer is reading a lean condition and is trying to richen up the mixture but is unable to fully compensate for the condition. That is why the engine is running so rich and you are losing mileage. You should be looking for an air leak in the intake system after the MAF, a vacuum leak into the intake manifold, or an exhaust leak at the exhaust manifold gasket or some where above the oxygen sensor. The O2 sensor is seeing excess oxygen that is unaccounted for by the MAF.

1996 T100 Toyota, will not start when hot, will start when cold but the engine light is on. Code says LB running lean? Allready replaced converter and sensors.


First thing that needs to be checked is the abscence of spark when it will not start. Running lean could be a vacuum leak on the left side or perhaps a clogged injector. How does it run when it does start?
