It could be a faulty front O2 sensor or a faulty coolant temperature sensor. A basd temperature sensor could be letting the engine run lean and the O2 sensor is picking this up.

    Before you replace anything, have realtime data read while the engine is running an at operating temperature. This will determine weather its the O2 sensor or the ECTS (engine coolant temperature sensor).

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

it's your fuel injection system bank one would be injector one. so my advice, replace the fuel injectors after first dropping fuel tank and looking for any sediment in base of tank.

2000 SATURN SL 1.9 TWIN CAM-PO171 CODE


very important oem or aftermarket 02........ big difference... one trouble shooting tech is to fill tank use mid grade gas and add to bottles of injector cleaner addative to tank clear code and run see if still same code..... also make sure plugs are basic plugs no high dollar split fire or so..if still no good get a name brand can carb cleaner... with car running.. open intake and spray cleany continously while you work the throttle with the other hand .. keep it just barely running this will burn off any carbon and clean 02's... even new ones... if still prob write me back for more steps

codes are for fuel system lean bank 1 and 2. low fuel pressure or innacurate mass air flow sensor could cause this. most common is mass air flow sensor.

OBD II Code


It is telling you the fuel system is not seeing any closed loop switching, the signal from an O2 always varies between rich and lean, back and forth, you can have 3 things going on, one the O2 is lazy or has failed, but most times that would trip a lean code, the more likely cause is a problem in the fuel control, either to rich or to lean. without the actual voltage readings from the O2 it is hard to tell you what to replace, do you have a system monitor tool?
