Hello,
2014 mustang Gt premium (low mileage 18k garage kept)is throwing B1A76:15 & P2068 code when tank is over about 1/2 full. Checked senders for correct ohm reading and checked wiring as per Ford pinpoint test-all checked good pointing toward IPC issue. At the sender plugs I’m showing 4.5v to ground on all except the return on sender 2 (WT/VT wire- pass side) is showing 10.5v.
Any ideas? How can I determine it is the IPC definitely?
Gas gauge is currently showing 1/2 tank when it’s nearly full. If I clear codes -gauge will be accurate(full) but it will throw code again shortly and gauge moves to 1/2 tank.
