Oxygen Sensors
Also called as the lambda sensor, an oxygen sensor measures the proportion of oxygen in liquid or gas. Scientists use this electronic device in measuring respiration or production of oxygen. Oxygen sensors are also used in automobiles.

Code readers are used for scanning engine codes on cars when the check engine light comes on. Basic code readers are great for checking engine "P" codes however to read codes and view data for other systems like ABS, SRS, Climate control etc, a automotive scanner that has more features is required. Code readers like the ones available at DenLorsTools.com are perfect for any car owner that would like to be able to scan their own check engine light. It could pay for itself quickly considerring that even leaving the gas cap off can set a code (this could cost $70 plus to have a shop read and clear). == ==
What needs to be done when check engine light on?
Have vehicle scanned to determine the problem - usually in the emission system Have vehicle scanned to determine the problem - usually in the emission system
Where is bank 2 to replace an o2 sensor on a Ford Freestar?
Bank 2 is the the front row of engine cylinders.
Sensor 1 is likely to be seen looking straight down between the engine and radiator, mounting into the exhaust pipe.
Sensor 2 is further down the exhaust system, after, or "downstream" from the catalytic converter.
Bank 1, by the process of elimination of course is the row back by the firewall/windshield.
Engine Cylinder Numbers & Names:
~Windshield~
1 - 2 - 3 Bank 2
4 - 5 - 6 Bank 1
~Front of Van~
2 other terms you'll hear when talking about O2 sensors: Upstream and downstream.
These terms are in reference to the catalytic converter and the flow of the exhaust gases. So the sensor that is closest to the engine is upstream from the converter - and not surprisingly, the sensor after are downstream.

Where is the o2 sensor at on a 1997 ford 4.2 f150 piokup?
On the exhaust pipes, may be more than one, most vehicles have 1 each bank and after convertor. The 2 upstreams control mixture.
What size wrench do you need to remove the oxygen sensor in a 98 Ford Taurus?
The O2 sensors use a 7/8th wrench - special sockets with a slot cut into them to accommodate the wiring are also available.

Where is the Oxygen sensor on a 1999 Monte Carlo 3100 V6?
There will be 4 Oxygen sensors and they ALL are mounted in the exhaust system. 2 near the point where the manifold connects to the headpipe and two more typically after the catalytic converter. The first two are typically the only ones to give trouble. Replace them both at the same time and wait until the engine is cool. Otherwise it's almost a certainty that you'll burn yourself.
Where is the oxygen sensor on a 2000 Mitsubishi Lancer ES located?
What is the code for the 02 sensor on a 1995 Chevy Blazer?
How many oxygen sensors are in a 1998 Toyota Rav4?
You have two oxygen sensors in Toyota Rav4, One before the catalytic converter and another after.
Where are the oxygen sensors on a 97 sunfire with a 2.4 engine?
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
How many oxygen sensors are on the 2001 jetta?
I just got told there were 2 sensors by shop fixing my 2001 VW Jetta V6, one in front and one behind the engine. Shop said they cost $80 a piece. Apparantly this is cheaper than a lot of other sensors for foreign cars ($200+ for BMW and Audi?) because the VW Jetta ones tend to fail every 40,000 miles unlike normal ones ... As a result of this glitch the replacements were made cheaper ... Not sure about that, but that's what I was told. Hope this helps There is one before the catalytic converter and one after it. The one before (called the "pre-cat" sensor) is usually the one that fails and the more expensive of the two. OEM sensors are under $100. Bosch sensors are about $120.
What is the location of the oxygen sensor on the 2000 Honda Civic?
All O2 sensors are located somewhere on the exhaust system.
Where is the camshaft position sensor on a 2002 Dodge Intrepid?
CRANKSHAFT POSITION SENSOR
The crankshaft sensor is located on the passengers side of the transmission housing, above the differential housing Crankshaft Position Sensor The bottom of the sensor sits above the drive plate
REMOVAL
Disconnect electrical connector from crankshaft position sensor.
Remove sensor mounting screw. Remove sensor.
INSTALLATION
Install sensor and push sensor down until contact is made with the transmission case. While holding the sensor in this position, install and tighten the retaining bolt to 12 N·m (105 in. lbs.) torque.
Connect electrical connector to crankshaft position sensor.
What would cause the engine light to come on and stay on while driving a 2002 Jeep Liberty?
get an engine diagnostic scan.
Where is the o2 sensor located on a 91 Honda civic hatchback?
its on the left side of the exhaust manifold it should have a wire leading to it
Where is the oxygen sensor on a 98 Lexus es300?
there is usally 3 o2 sensors 1 on the front of your motor looks like a spark plug sticking out and one on your exsaust and another one somewhere else look on google
A compression flange is used to connect a toilet to the sewer line.
How do you replace oxygen sensor 1 bank 1 Subaru Forester 2003?
Unplug then unscrew the old one. Screw the new one in and plug it into the wiring harness. Special sockets that will help you to remove the oxy sensor are available for loan at many auto parts stores.
What can you do if the threads are stripped on the O2 sensor?
If the threads of the sensor are stripped, it must be replaced. When this happens, the threads on the exhaust are usually also damaged. These can be repaired by "chasing" them with the appropriately sized tap. Be sure to use high temp. anti-seize on the new sensor. Sensors should only be removed when the exhaust system is at operating temperature.
What is an Oxygen sensor remover and where can you find one?
It is a specially designed socket that has a slit on the side so you can connect it to the O2 sensor and have the O2 sensor wires come through that slit. You can get them at Sears and probable auto parts stores. They work well. HTH
