Guys,

Where can I get an extension (plug and play) for the o2 sensor?

Especially curious to hear where the Canadian folks get this (if there's anything local).

Thanks!

amazon and ebay come to mind. Or make your own out of old connectors, wire, and wire-loom.

When i did my IAT senor, i just cut it in the middle and added two wires. Taped it up and it been going fine for the last 2 years. Twist and tape is the only way to do wire connections

Yeah,

I think the O2 relies on resistance in the wire as well if I recall correctly?

Thanks guys

I know that's been said, but I highly doubt it. I have not seen any theoretical basis for it. In any event, a well-made splice (twisted and/or soldered) should not affect performance as much as an extension cable would. Every plug-in connector adds a little resistance, and different metals at the junctions can be detrimental over time. I have used crimped connectors to extend the post-CAT O2 sensor for years with no codes, but the upstream O2 throws codes just from headers being installed, using stock wiring.

Heated Oxygen Sensor Wiring Repairs

J-38125 Terminal Repair Kit

Notice: Do not solder repairs under any circumstances as this could result in the air reference being obstructed.

If the heated oxygen sensor pigtail wiring, connector, or terminal is damaged the entire oxygen sensor assembly must be replaced. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly it must have a clean air reference. This clean air reference is obtained by way of the oxygen sensor signal and heater wires. Any attempt to repair the wires, connectors or terminals could result in the obstruction of the air reference and degrade oxygen sensor performance.

The following guidelines should be used when servicing the heated oxygen sensor:

• Do not apply contact cleaner or other materials to the sensor or vehicle harness connectors. These materials may get into the sensor, causing poor performance. Also, the sensor pigtail and harness wires must not be damaged in such a way that the wires inside are exposed. This could provide a path for foreign materials to enter the sensor and cause performance problems.
• Neither the sensor nor vehicle lead wires should be bent sharply or kinked. Sharp bends, kinks, etc., could block the reference air path through the lead wire.
• Do not remove or defeat the oxygen sensor ground wire (where applicable). Vehicles that utilize the ground wire sensor may rely on this ground as the only ground contact to the sensor. Removal of the ground wire will also cause poor engine performance.
• To prevent damage due to water intrusion, be sure that the peripheral seal remains intact on the vehicle harness connector.
The engine harness may be repaired using the J-38125 .

It's not the resistance, it's the clean air reference.

based off what was said in an earlier thread even soldering it will mess up the signal...you shouldn't redo a wire without soldering or at least using the connectors, otherwise it is just waiting to slip apart.
