this resets all brains in the car, even lost radio channels saved, sorry
or with shop manual
find he TCM , my guess its inside the PCM
'find the PCM memory fuse, ours are called IOD fuses.
pull it for 1hr.
F1.20 (10amps) is memory I think. PCM it is hot all times.
BJB ,battery fuse box, top center fuse 1.20. to left of 1.9
first unplug mass sensor make sure not corroded or a bent pin when plug back in make sure tight then unplug neg from battery for about 30 minutes will clear codes, might be the sensor itself
It might but what exactly are the codes. Before you change the Mass air flow sensor, try cleaning it first with a can of mass flow cleaner.
If your running a oil K&N filter, there could be some oil residue on the sensor. Start with that and change the filter or clean it if it's a K&N.
The O2 sensor's could be bad also, you really need the code's to be sure what sensor is giving you the faulty signal.
Good luck and hope this helps.
