Hi all, I am new to this site and have been battling an on going issue with my 02 HX. I have P codes 0147 and 1130. I replaced both the #2 and #3 O2 sensors with the NTK OEM version with no change. When I try to reset the ECU for the check engine light, it clears, but as soon as I unplug the OBD2 scanner the light immediately turns back on. Is this a hard fault and why. I had the stealership look it over and originally thought it was a bad ecu. That was not the problem. They thought it might be the primary A/Fuel ratio sensor but with no P1163 code, I hate wasting my money. I fear it's a wiring problem because nobody can reset the check engine light without it coming on immediately after unplugging scanner. Any ideas or thoughts would be appreciated. Car has 158000 miles and runs like a top but need it inspected. Thanks in advance.
