Hello,
Wondering if anyone has any experience or can help me with this.
2011 Ram 1500 4.7L
Had multiple O2 sensor codes for both upstream and downstream sensors on bank 1 - one of them being P2246 5V ref circuit high. I replaced both O2 sensors on bank one thinking they were probably shorted internally. Fault code P2246 O2 sensor B1S1 5 volt reference high came back. Now thinking that the O2 sensors shared a commons 5V ref I jumped the 5V ref from B1S2 to B1S1. I literally cut the 5V reference wire on chassis harness and ran new wire from downstream sensor. Code still came back. I need help!!!! Thanks in advance.
