There are 4 Oxygen Sensors on your vehicle,BUT that code does not tell you to replace the sensors,see link below,copy and paste,read….

How to change the oxygen sensors on a Ford Expedition?

Compare the old sensor with the new one and make sure they match up. Apply a light coat of anti-seize compound to the threads of the new sensor and install it by hand first. Tighten the sensor using the ratchet and sensor socket, but do not over tighten or the sensor and threads may be damaged. Plug the oxygen sensor electrical connector.

Where are the oxygen sensors located on a Ford 4.6L?

Since the Ford 4.6L, 5.4L Engines have four oxygen sensors, this article concentrates on testing the two that are before the catalytic converter ( O2S11 and O2S21 ). Important Suggestions And Tips. Symptoms Of A Bad Oxygen Sensor. Oxygen Sensor Basics. Where Are 02S11 And O2S21 Located? Oxygen Sensor Test 1. Oxygen Sensor Codes Keep Coming Back.

When do you need to replace the oxygen sensor?

In a 2005 model, as is the case with this project vehicle, it uses a pair of oxygen sensors to send data to the truck’s computer, to ensure that emissions and performance are all in proper order. When these go out, the engine light will come on in the dashboard, and you will have to replace them.

Where can I get a 2003 Ford Explorer replaced?

His work has appeared in Texas, New Mexico and Miami and on various websites. Ferrell is a certified automation and control technician from the Advanced Technology Center in El Paso, Texas. How to Replace a 2003 Ford Explorer O2 …

How do you replace an oxygen sensor on a car?

Unplug the wiring harnesses on the sensors and remove the sensors using the oxygen sensor wrench. Use the applicator provided with the anti-seize compound to apply anti-seize compound to the threads of the replacement oxygen sensors. Be very careful not to get any of the compound on the sensor body itself.

What is the problem code for the oxygen sensor?

P0153: Upstream Heated Oxygen Sensor (HO2S11) Circuit Slow Response (Bank 2). This diagnostic trouble code (DTC) is letting you know that the upstream oxygen sensor for Bank 2 is switching between a Rich and Lean condition very slowly (lazily).

How does a portable oxygen gas detector work?

The Portable Oxygen Gas Detectors can detect smallest leak of Oxygen gas with display of gas concentrations on LCD display. These detectors have the feature of easy handling and programming with 3 keys and power supply with rechargeable batteries and on/ off option.

What kind of oxygen detector does industrial scientific use?

Industrial Scientific provides a range of monitors including the GasBadge® Pro single-gas detector, the Ventis® Pro, Ventis® MX4, MX6 iBrid® multi-gas detectors, and the Radius® BZ1 Area Monitor, to monitor oxygen levels. Maximum “Safe Level”; OSHA. Oxygen Concentration of AIR (20.954).

What kind of oxygen sensor is used in scuba diving?

The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and trimix.

How are oxygen sensors used to measure respiration?

Divers also use a similar device to measure the partial pressure of oxygen in their breathing gas. An oxygen sensor will typically generate up to about 0.9 volt when the fuel mixture is rich and there is little unburned oxygen in the exhaust. Scientists use oxygen sensors to measure respiration or production of oxygen and use a different approach.

How to change the oxygen sensors on a Ford Expedition?

Where is the oxygen sensor in the engine?

An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.

Can a bad oxygen sensor cause a check engine light to come on?

The trouble codes associated with the OBDII scan will reveal which sensor is at fault and why it is bad (at least what the computer thinks is wrong). It is very rare for there to be a problem with an oxygen sensor, and not have the check engine light come on. Here are the most common symptoms of a bad oxygen sensor in your Expedition :

How does the oxygen key system identify you?

• Key System: Our key-system uses your HWID commonly known as hardware ID to identify you from other users, so a key can be made for each user. It also uses your IP address which stands for Internet Protocol which is a unique address that identifies people using the web/Internet which is also being used to identify your key for the key system.
