Extended O2 sensor wiring now P0031 P0037 codes

[stilson]

G'day guys,

I had my O2 sensor wires extended by the auto sparky and fitted a set of UELs and threw a CEL which I assumed was a P0240 (inef cat) but when I connected the OBD2 the codes were P0031 and P0037 (bank 1 sensors 1&2 heater faults). Im thinking a possible bad connection but on both sensors?

Any thoughts or advice on this?

Do either of these codes but the motor into limp mode?

Unplugged sensors to test heater resistance. 2.8ohm and 5.2ohm - within spec.
Plugged back in and started car, CEL clears.

I can only assume there was a bad connection on the plug.

I'm just glad I fixed it without replacing sensors or moving sensor ports.
