So a while back I replaced my O2 sensors and because I have LT headers I had to get the O2 extensions. Well the zip tie broke on one side and the extension drug the ground and the wires were frayed. I sodered all the wires back together and flased the ECU. After 50 miles or so the light came back on. i took it to auto zone and i dont remember the code, but it said that there was poor flow from the sensor.
Is there a problem with the soder? or what? Any one have any ideas cause its killing my fuel economy!

"low current to/from sensor" maybe?


if the soldering was half-assed the resistance will be higher (hence the low current) and it'll throw a code. the o2's operate at less than 1v so just a little resistance would make a difference. would help to know the actual code though

+1 for bad solder job.

Try to replace the whole harness if you can.
