4 Codes in computer


code p0128 indicates a mechanical fault ( could be the thermostat stuck open)
code p0174 -system too lean -bank2 ===causes --intake /exhaust leak--fuel pressure/pump--injectors--AIR system--hose connection/s
code po171 refers to system too lean bank 1 same as po174 with the HO2S sensor being the culprit. As to all being related . only by way of the o2 sensors
code p0442 is not connected to the first 3 as it is in a different section of the fuel system

2001 Chevy Impala 3.8L. P0171 lean fuel code. We have replaced the MAF from a previous code. O2 sensors scan good, as does the fuel pump all within specs. Car is running like junk. 81K, Dropped Cat...


DTC P0171 - System Too Lean (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.

According woth your previous tasks, inspect all vacuum and PCV hoses, replace if necessary.

My 2000 Toyo. Tacoma Prerunner TRD V6, truck Failed smog due to the part #3 Functional Computer Tests due to an erased MIL. But had passed the Visual Inspection, and Emissions. So i bought a Code reader...


there are 2 sensors in the system
one is a heated oxygen sensor (HO2S) in the exhaust manifold / pipe before the cat converter that reports the exhaust gas composition to the ECM so that fuel/ air ratios can be adjusted
if that one is faulty it is most likely the reason for running lean or rich
the second sensor is the oxygen sensor (O2) which is after the cat converter and reads the results of the cat converter cleaning the exhaust
you may have to replace both the sensors to get a clearance or replace the cat converter as well as the HO2S unit

Ok i got a 2002 saturn vue..code was saying bank 1 bank 2 running lean..the vue runs perfect ,sometime at park it would idle hi.anyways i have replaced the mass air flow unit..turn off light,comes back on...


I had exactly the same problem .Mine was corrected with replacing the O2 sensors .The sensors cost less than $30 each but cost about 20 mins labor per sensor .So if you got an honest mechanic the total cost will be around $130 .

2002 SATURN VUE- SERVICE ENGINE LIGHT HAS BEEN ON FOR 1 1/2 YRS.


Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you will need to have the car diagnosed and repaired.
