There are 2 of them one is located by the exhaust manifold the other is ferther down the exhaust usually past the catalytic converter which looks like a small muffler. unplug the sensor, unscrew the sensor. screw the new one in and plug it in. If you have a service engine soon light on. You have to either reset it with an OBD 2 but make sure your car is OBD 2 compliants. they can be bought at most auto stores $40 and up . reads the codes tells you what you need to replace and can reset thus erase the codes and turns the light out. PS if you reset this you`ll have to drive your car about 80 miles of so for the cars computers to reconfigure the maximum effeciency. and until you drive and the computer reconfigures you won`t pass inspection.

How doi change i change the o2sensor on a 2001 dodge durango


You will need an O2 sensor socket and a 1/2" drive rachet or 1/2" to 3/8 step down adapter. There are two O2 sensors, one for each bank of cylinders just off the exhaust manifolds.

I have a 1998 isuzu Amigo 2.2L 4 cylinder. I get 2 codes that stay on all the time and I can't figure out the problem: PO300 and PO141(pending). I have trouble starting it, exhaust smells bad at times,...


P0141 O2Sensor Heater Circuit Malfunction (Bank #1 Sensor #2)
P0300 Random/Multiple Cylinder Misfire Detected

The random multiple cylinder misfire can be caused by a bad O2 Sensor.

Try to change the O2 Sensor out, they can be tricky though, with the threads sometimes becoming gauled if removed when cold.

REMOVAL & INSTALLATION
  1. Start the engine and allow it to reach normal operating temperature, then turn the ignition switch OFF.
  2. Disconnect the negative battery cable.
  3. Open the hood and locate the O2sensor connector. It may be necessary to raise and safely support the vehicle for access to the sensor and its connector. NOTE: On a few models, it may be necessary to remove the passenger seat and lift the carpeting in order to access the connector for a downstream O2sensor. Fig. 1: Since sensor locations vary between vehicles, the first step in removal is to locate the O2sensors (arrows) . . . 90914p02.jpg
    Fig. 2: . . . and the sensor connector (2), which is usually near the O2sensor (1), but removed enough from the heat of the exhaust system 89714p26.jpg
    Fig. 3: Disengage the sensor pigtail connector half from the vehicle harness connector half 90914p03.jpg
    Fig. 4: For flange type sensors, loosen the hold-down fasteners . . . 90914p04.jpg
    Fig. 5: . . . which happen to be nuts in this particular case - some models may use bolts rather than nuts 90914p05.jpg
    Fig. 6: Then, pull the sensor out of the exhaust component 90914p06.jpg
    Fig. 7: For screw-in type sensors (arrow) . . . 89714p22.jpg
    Fig. 8: . . . either use a box end wrench to loosen the sensor or a socket designed expressly for this purpose . . . 89714p23.jpg
    Fig. 9: . . . then remove the sensor from the exhaust component 89714p24.jpg

  4. Disengage the O2sensor pigtail connector from the vehicle harness connector. NOTE: There are generally 2 methods used to mount an O2sensor in the exhaust system. Either the O2sensor is threaded directly into the exhaust component (screw-in type) or the O2sensor is retained by a flange and 2 nuts or bolts (flange type). WARNING
    To prevent damaging a screw-in type O2sensor, if excessive force is needed to remove the sensor lubricate it with penetrating oil prior to removal. Also, be sure to protect the tip of the sensor; O2sensor tips are very sensitive and may be easily damaged if allowed to strike or come in contact with other objects.
  5. Remove the sensor, as follows:
    • Screw-in type sensors: Since O2sensors are usually designed with a permanently-attached wiring pigtail, it may be necessary to use a socket or wrench that is designed specifically for this purpose. Before purchasing such a socket, be sure that you can't save some money by using a box end wrench for sensor removal.
    • Flange type sensors: Loosen the hold-down nuts or bolts and pull the sensor out of the exhaust component. Be sure to remove and discard the old sensor gasket, if equipped. You will need a new gasket for installation.
  6. Perform a visual inspection of the sensor. Black sooty deposits may indicate a rich air/fuel mixture, brown deposits may indicate an oil consumption problem, and white gritty deposits may indicate an internal coolant leak. All of these conditions can destroy a new sensor if not corrected before installation. To install:
  7. Install the sensor, as follows: NOTE: A special anti-seize compound is used on most screw-in type O2sensor threads, and is designed to ease O2sensor removal. New sensors usually have the compound already applied to the threads. However, if installing the old O2sensor or the new sensor did not come with compound, apply a thin coating of electrically conductive anti-seize compound to the sensor threads. WARNING
    Be sure to prevent any of the anti-seize compound from coming in contact with the O2sensor tip. Also, take precautions to protect the sensor tip from physical damage during installation.
    • Screw-in type sensors: Install the sensor in the mounting boss, then tighten it securely.
    • Flange type sensors: Position a new sensor gasket on the exhaust component and insert the sensor. Tighten the hold-down fasteners securely and evenly.
  8. Reattach the sensor pigtail connector to the vehicle harness connector.
  9. Lower the vehicle.
  10. Connect the negative battery cable.
  11. Start the engine and ensure no Diagnostic Trouble Codes (DTC's) are set.

How to change oxigen sensor


Take a 7/8" or 22mm wrench and remove counterclockwise, but unplug before removing. Do the opposite to install O2sensor. Some require special sockets to remove due to where the o2 sensor is located. O2 sensors are located on the exhaust near the exhaust manifold before the catalytic converter and just after the catalytic converter.

2002 Ford Windstar Error Code P1131 And P1151


those two codes are for the o2 sensors. both are the upstream sensors on the front and rear banks. so they are desinagted bank 1 sensor 1 and bank 2 sensor 1. them most common cause for this is faulty o2sensors , bad gas and of a poor running engine. so if your car runs good (no misfire) and gas is ok then replace the o2sensor witch is the very most common cause.

Cant find o2 sensors


if you follow your exhaust system you will find the o2 sensors they could have one right off the exhaust manifold and your second o2 is going to be behind the catalytic converter. so you will have a o2sensor before and after the catalytic converter on the exhaust hope this helps you out.
please rate me if you would
thank you
