145,000 miles on a 2004 TJ and Check Engine Light comes on. Turn ign. key 3 times and get P0138 code. Am looking to replace all 4 O2 sensors based on the recommendations on this site. Some of the O2 sensors list NTK as the manufacturer and NGK as the brand on the spec. sheet. Here are the questions:
1) Can O2 sensors showing NTK as the manufacturer & NGK as the brand be used with O2 sensors that show NGK as the manufacturer and NGK as the brand?
2) Any issues with the computer receiving the wrong input from the mismatch?
3) Should battery ground be disconnected during replacement?
Thanks in advance. Better safe than sorry.
