DOHCRagtopguy Posted February 7, 2003 Report Share Posted February 7, 2003 Wife's 3.4 is throwing a code 1-3 Open circuit for O2 Sensor. Where the hell is the connector at? I looked in that inch of space behind the plenum and can't seem to find it. Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted February 8, 2003 Report Share Posted February 8, 2003 if its anything like the 3.1MPFI's o2 sensor, then its on the rear exhaust manifold right in the center....it might be best to jack the car up if you have access to a lift to change it if you're not removing the plenum.....I'm sure one of the DOHC guys will tell ya exactly how to do it....hope this helps in some way and good luck!

chronic139 Posted February 8, 2003 Report Share Posted February 8, 2003 the sensor is on the pipe after the rear manifold and crossover pipe come together. you can only see it from the bottom. its a pretty tight fit. Quote Link to comment Share on other sites More sharing options...
DOHCRagtopguy Posted February 9, 2003 Author Report Share Posted February 9, 2003 Yea, I know where the sensor is, I'm taliking about where the connector is at in the wire cluster. That's where I can't find the pain in the ass. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted February 10, 2003 Report Share Posted February 10, 2003 It sort of dangles back there behind the plenum. At least that's how it is on my '94. Quote Link to comment Share on other sites More sharing options...
