Hi All,
Ive got a 99 Disco 1, great truck and great fun with 217 K km on it.

A few weeks ago got CEL and finally read the codes, they were P0130 and P0133. Both refer to drivers side oxygen sensor. I replaced the sensor with a new one.

Drove for 2 hrs today, CEL came on again. Checked the codes and again, same codes appeared.

Any suggestions, any simple fault diagonistics that I can do to narrow down the problem since it does not seem to be the oxygen sensor.

Thanks, super forum.

Mark
