1151 lean bank 2, 1152 rich bank 2. This could be one of two things.
One code is old and no longer valid. Clear the codes and retest.
If only one code comes back after reset, swap the upstream sensors between banks. If the problem stays with the sensor, replace it. If it stays with the bank, check the harness and let us know if itā??s lean or rich.
Since bank 2 canā??t be lean and rich at the same time it sounds like a harness problem. Possibly a short from brunt insulation.
Since you donā??t have a lot of $$ to spend, switch the upstream O2s between bank 1 and two. Reset your codes and retest. If it still says bank 2 lean/rich (at the same time) fix the harness. If the problem jumps to bank 1, buy a new O2 sensor.
