Codes P0420 and p0430
After trans rebuild I have been getting randomly. I have replaced both upstream O2 sensors and every other week I get the code on onside or the other.
Last thing I have done is clean the MAF sensor and air temp sensor. So far no issues. But if it comes back any ideas? Oh if this does come back I have heard it can fail you on emission testing I am good for another 9 months. |
