O2 Sensor

[DeadBlade89]

My O2 sensor is too short for my new header. How should I go along in making it long enough? Can I just cut the wires and add some to make it longer or wont that work? Thx

Yep, pacesetter's come with new wire to lengthen them. Just make sure you cut properly. Cut in between the sensor and the clip. Not in between clip and PCM

ok, thx cody. so its just normal old wire, nothing special about it like a resistor wire?

[Classicrocjunkie]

Nope, its either 18 or 16 gauge wire.

oh, make sure you solder the connections and use heat shrink over black tape. The sensors are prone to getting hit with water since they are soo low.

ok, thx alot cody

The confusion over whether or not to splice likely stems from the earlier O² sensor which used their hollow wire as a supply for reference air at the zirconia element junction. This scheme was mostly abandoned by the late 1980s, and a reference air supply vent was provided in the sensor body. Improperly crimping or soldering the leads on early style O² sensors could block the supply of reference air and render the sensor useless (permanently rich) to the control system. You should be able to safely extend the length of any lead in the O² sensor circuit on later vehicles or those which have had the sensors replaced with a later, more modern style.

Relivance?
