How to reset computer code for 1997 olds aurora... I changed the mass air flow sensor and the throtle position senor twice but still not running right.... has to be the codes

Did you ck the acc fuse sounds like that is what happened , did u unplug anything when doing the radio ,why if the car was running good before you changed the radio you would even go under the hood an start changing parts

Undo your battery overnight so the computer will reset and see if that helps.if it does not you will probably have to take it to an auto parts store and see if they can reset it

code po172 is your bank 1 o2 sensor and code po121 is your throttle posit sensor that controls your RPMs .code po102 is your maf -mass air flow sensor. and code 01172 is a throw in code from the others cause problem. you need a o2 sensor and mass air flow sensor and throttle position senor

the throttle position sensor controls the rpms and the mass air flow meter controls or i should say reads how much air is going threw the air intake

P0100 NISSAN - Mass Air Flow Sensor Circuit Range/Performance Error

Possible causes- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor
Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.

They say running lean, did you happen to get the code. Could be a number of things. I would start by checking vacuum lines, confirm they have no leaks, cracks, and have all in correct places. Second o2 sensors, confirm they are good. Third check and make sure you throttle and intake are clean, and check the throttle position sensor and mass air flow sensor to make sure they are working correctly. Good Luck.

mass air flow senor will cause this problem don't have code book to translate what fourteen means but i would check to see air filter tube that connects airfilter to throttlebody has a crack or something wrong with mass air flow sensor or possibilly be a bad thottle position sensor

Have the mass air flow sensor chk'ed . It detects air going through he intake. If it senses nothing, it will cut off the fuel. A plug i diagnostic check may reveal the exact cause. Take it to a shop that has a code reader. That would be best.

ok, this is simple to do but I would get the Chilton for your car so you can have pictures of what to do. You can get the chilton at the parts store, or the library. It sounds like a throtle body sensor or the throtle body itself, but could also be your air idle control sensor. go down and buy some mass air flow sensor cleaner and a BIG can of carb cleaner. First clean the mass air flow sensor neer the air filter. then remove the throtle body it is held in by 4 botls and you may need a new gasket, NO GASKET GLUE. Now take that big old can of carb cleaner and start cleaning in and out. also down into manifold. clean everything. Now put it back together, remember 4 bolts and no gasket glue. if the problem continues replace the throtle body sensor. and then the idle air intake. It will be cheaper to take it into the part store and have them put it on the computer. They can often tell you what sensor it is ahead of all this but don't let this stop you from cleaning out the throtle body, it will make your car run better and longer.

tepfy

did you reset the computer after changing the egr? do this by removing the positive battery cable for 10 mins.

If this doe snot work, replace the mass air flow sensor, that is the unit the air filter tube connects to, it has a wire going to it.
