Bank 1 system too lean code po171 how to repair


code p 0171 refers to system too lean bank 1===causes --intake/exhaust leak---AIR system---MAF/VAF sensor---fuel pressure/ pump/ pressure regulator---injector/s---heated oxygen sensor (HO2S unit in the exhaust manifold or before the cat converter
If the engine is running well then consider replacing the HO2S unit as that reports to the ECM that then adjusts the mixture for that bank by altering injector amounts and timing
all the rest affect both banks but the code is bank 1 specific

More than likely bank 1 sensor has a possible vacuum leak, or a lean misfire on that side of the bank.(lean misfire happens when gap of spark plug are exceed due to wear), As for the 02 sensor I agree that it is reporting the true engine condition on that side of the bank

Code Po171 indicates a lean condition on cylinder bank #1 of the engine. This is the drivers side of the engine. I would suggest replacing both front oxygen sensors as a pair to start. An oxygen sensor has a life span of about 5 years and yours are now 9 years old if they are original. When they get older they are slow to respond to changes in the oxygen content of the exhaust and can trigger a code Po171. If you continue to have the same code set after the replacement of both oxygen sensors then it is time to find out why your engine is running lean. Some of the most common causes are an ignition misfire and a vacuum leak. I have also seen Fords EGR flow sensor (known by Ford as Delta Pressure Feedback sensor) to cause problems like that as well. A good mechanic with a scan tool can usually spot a problem like that in a few minutes.
