What is p0037 for?
Hi there:That P0037 is for the downstream sensor on bank 1. This is the rear sensor on the passenger side front cat converter. It is the one with the black connector. There are special O2 sensor sockets and wrenches which make it easier to remove but all you need is a 7/8" or 22mm wrench.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.
