Where is front o2 plug

[phunny]

Hey I just ported my manifold turbo and o2 dump and when I put everything back together the o2 reads .2 or .4v all the time. I'm using a palm pilot and its bank 1. Just wondering if i plugged it in to the wrong place. I have it plugged into the harness right below the fuse box.

bank 1, sensor 1 or sensor 2

You could have destroyed it when takeing it out to by ruff housing it. Even dropping old o2 sensors off a tool bench can kill them. Clean the connector put back together and good luck.

You can monitor the o2 sensor's voltage with a multimeter while the car is running to see if it really is stuck or if you messed up the wiring

how?

how?

if you have a 4 wire o2 sensor, 2 are used for the heater and 2 are used for the actual voltage being read. Measure the voltge on the 2 pins for the sensors output.
