I take it the wiring has been ripped off from the underside to the sensor. You will just have to follow the wiring from the connector under the carpet under the passenger seat inside the car to where it exits to the exhaust. Fit the new sensor with an open ended spanner, carefully feed the wires/plug back through to the connector. The oxygen sensor has four wires. Two, usually grey, are to supply the sensor heater with power, they only work when hot so they have internal heaters. The other two wires are the signal feeds back to the ECU that report on oxygen levels.

O2 sensor front Volvo s60t5. Where is it located? A check engine is illuminated

Follow the exhaust manifold down to the tailpipe. The Oxygen sensor is located on the exhaust manifold or exhaust pipe. There will be wires going to it.

Good luck on finding the O2 sensor.

Odds are, the O2 sensor is just detecting an imbalance in the Air/Fuel ratio, therfor causing your O2 sensor code.

Start by changing your spark plug wires, if it hasn't been done in a while.

Is it hard to change the O2 sensor on the exhaust pipe?

IYou need a special socket which is available at any auto parts store. It has a slot in it for the wires to fit and uses a 1/2 inch ratchet. If the sensor was working before the wires were cut, why not splice them back together. A few **** connectors and some heat shrink tube and you would be back on the road for about $10 instead of paying for a new sensor and socket. Hope this helps.

Where can I find a diagram that shows where the Oxygen sensor is on a 2002 Kia Rio?

The o2 sensor is located in the exhaust pipe. follow the exhaust down under the engine until you see a short cylinder with a nut shaped end sticking out, It will have a wire sticking out of it . The sensor will not point at the ground but up where no road debris would break if off. You wll need a special O2 sensor tool to remove it,about $15 or can be borrowed from some auto parts stores

Getting code p1135 and p1155 on toyota rav4 2002

Here's what the codes mean:
P1135 Air/Fuel Sensor Heater Circuit Response (Bank 1 Sensor 1)
P1155 Air/Fuel Sensor Heater Circuit. (Bank 1 Sensor 2

This is mainly related to the oxygen sensors. It maybe the sensors themselves or an open wire going to te sensors. They are mainly located on the exhaust pipe. One before and on after the catalytic converter.

Installing an o2 sensor

The O2 sensor goes in the exhaust pipe just below the exhaust manifold. That model may have an O2 sensor on each side of the engine, but they should be the only thing screwed into the exhaust pipe. And I would use TOYOTA brand parts or, if you have to replace it again,(and you probably would), you may have trouble getting it out.

There is one before each catalytic converter (usually up right near the exhaust manifolds), and one after each cat (or if you have a Y-pipe exhaust that brings the two sides together to one pipe and one converter, then there's one after that single converter). Why do you want to change them? Have you gotten failure codes or are you having poor gas mileage? Or have they just been in there a long time? They're usually good for about 60k miles, although of course they can fail early. Usually the symptoms are poor fuel economy, running rich (seen by black smoke out the tailpipes and some rough idling, as well as blackened spark plugs), or fault codes dealing with system-lean or system-rich descriptions. Those symptoms are indicative of bad primary O2 sensors (the ones closest to the engine). If your secondary sensor(s) are failing (the post-cat sensor or sensors) you'll trip a check-engine light warning you of poor catalytic converter efficiency.
