ok. so i did my second seafoam about a week ago. my check engine light came on, no surprise, did the run right for about 15 mins. still didnt come off. so i figured it would after a few days of driving finally went to see what it was. it came up o2 sensor and manufacture AUX input and output ( p1676) any ideas? can i just reset my ECU? thanks

 

that code has nothing to do with the seafoam. that is a code for the ignition switch (eletrical portion)P1676
