2007 tl type s where is bank 2 sensor 1 oxygen sensor located. What is the replacement number of a sensor to kill Emission p0171 Notice and light


Oxygen sensors monitor the exhaust stream, comparing the oxygen content in it to the oxygen content of ambient air. When oxygen content is low, sensor voltage is high. When oxygen content is high, sensor voltage is low. The voltage created by the sensor is sent to the DME (engine control module) to help maintain a proper fuel mixture. The mixture preparation is used to keep the catalytic converters running at peak efficiency. The oxygen sensors used in E60 models covered in this article has four wires. Two of which are for oxygen sensor heating and two for the signal. The heater is used to get the sensor online faster. Previously, exhaust heat was used. One wire supplied a ground to the sensor for the signal, and the other was for the sensor signal.
Oxygen sensors should be replaced every 100,000 miles. In a perfect world that would be it. Wait until a specified mileage and replace the sensor. However, these sensors fail prematurely, set oxygen sensor fault codes and reduce fuel economy. In this article, I will show you how to identify the location of all four oxygen sensors and how to replace them. You will need an oxygen sensor socket to remove the sensors and remember to always work with a cool exhaust. Oxygen sensors are fragile. Do not drop, as damage may occur. Also, keep the sensor tip clean when reinstalling.
Oxygen sensors are laid out in banks, which refer to cylinders and in sensor numbers referring to before or after the catalytic converter. Bank1 or B1 refers to cylinders 1-3. Bank 2 or B2 refers to cylinders 4-6. Sensor 1 or S1 refers to the sensor before the catalytic converter. Sensor 2 or S2 refers to the sensor after the catalytic converter.
Remember that your car may have been serviced before and parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.
Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Where is the bank 1 sensor 1 oxygen sensor located on a 2012 Ford Escape XLT 2.5L I-4?


Hi Adam
It is refering to the sensor located before the cat convertor eg the first sensor in the exhaust. The code is a generic code as the v6 engine has 2 banks that is why it refers the bank 1 just ignore that part of the code description.
Hope this answers your question.

Diragram on how to change the water pump on a 1995 z24 cavalier 2.3


Check this procedure, according with the repair guide for...

2.3L and 2.4L Engines
(see Figure 9)
  1. Disconnect the negative battery cable
  2. Detach the oxygen sensor connector.
  3. Properly drain the engine coolant into a suitable container. Remove the heater hose from the thermostat housing for more complete coolant drain.
  4. Remove upper exhaust manifold heat shield.
  5. Remove the bolt that attaches the exhaust manifold brace to the manifold.
  6. Remove the lower exhaust manifold heat shield.
  7. Break loose the manifold to exhaust pipe spring loaded bolts using a 13mm box wrench.
  8. Raise and safely support the vehicle.
It is necessary to relieve the spring pressure from 1 bolt prior to removing the second bolt. If the spring pressure is not relieved, it will cause the exhaust pipe to twist and bind up the bolt as it is removed.
  1. Unfasten the two radiator outlet pipe-to-water pump cover bolts.
  2. Remove the manifold to exhaust pipe bolts from the exhaust pipe flange as follows:
    1. Unscrew either bolt clockwise 4 turns.
    2. Remove the other bolt.
    3. Remove the first bolt.
On the 2.4L engines, DO NOT rotate the flex coupling more than 4° or damage may occur.Pull down and back on the exhaust pipe to disengage it from the exhaust manifold bolts.
  1. Remove the radiator outlet pipe from the oil pan and transaxle. If equipped with a manual transaxle, remove the exhaust manifold brace. Leave the lower radiator hose attached and pull down on the outlet pipe to remove it from the water pump. Leave the radiator outlet pipe hang.
  2. Carefully lower the vehicle.
  3. Unfasten the exhaust manifold-to-cylinder head retaining nuts, then remove the exhaust manifold, seals and gaskets.
  4. For the 2.4L engine, remove the front timing chain cover and the chain tensioner. For details, please refer to the procedure located later in this section.
  5. Unfasten the water pump-to-cylinder block bolts. Remove the water pump-to-timing chain housing nuts. Remove the water pump and cover mounting bolts and nuts. Remove the water pump and cover as an assembly, then separate the two pieces.

    1. Pump assembly-to-chain housing nuts-19 ft. lbs. (26 Nm).
    2. Pump cover-to-pump assembly-106 inch lbs. (12 Nm).
    3. Cover-to-block, bottom bolt first-19 ft. lbs. (26 Nm).
    4. Radiator outlet pipe assembly-to-pump cover-125 inch lbs. (14 Nm).
  5. Using new gaskets, install the exhaust manifold. Make sure to following the tightening sequence and torque specifications given in the exhaust manifold procedure located in this section.
  6. Raise and safely support the vehicle.
  7. Index the exhaust manifold bolts into the exhaust pipe flange.
  8. Connect the exhaust pipe to the manifold. Install the exhaust pipe flange bolts evenly and gradually to avoid binding. Turn the bolts in until fully seated.
  9. Connect the radiator outlet pipe to the transaxle and oil pan. Install the exhaust manifold brace, if removed.
  10. On the 2.4L engine, install the timing chain tensioner and front cover.
  11. Install the lower heat shield.
  12. Carefully lower the vehicle.

Starter location ?, 2002 sedan, installed new battery, won't start, I figure the starter may need a tap. It 'sometimes' clicks, but no engagement.


hello, most Hyundai starters are located at the front of the engine (radiator side) below and behind the exhaust manifold, accessability to the starter is from under the vehicle and is held in place by two 14mm bolts and may also have a heat sheild covering the starter.

They sell o2 sensor trickers for the exhaust online but you shouldn't need them. If it's off road then eliminate the computer and wire in the distributor yourself. If keeping the computer then figure out if the plug is a single misfire or random. Try changing plugs and wires.

How to replace oxygen sensors...where are they located


Follow the exhaust pipe from the manifold and you will find your sensors sticking out at 90 degs from the pipe, follow the wire and disconnect from the terminal. you will need a ring spanner or special socket normally about a 22mm ( varies from sensors to sensor ) and unscrew anti clockwise, then just fit new in reverse order

Changing thermostat in 2004 Rendezvous


The dealership will charge around $450 to change the thermostat on the 3.4L engine.
You have to remove the crossover exhaust manifold. Once that is out of the way, the thermostat itself is easy. Before the manifold is removed, I could only touch one of the two bolts holding the thermostat housing in place, much less get a wrench on it.

If your engine is the 3.4L then the instructions below will work:

REMOVAL: - Remove the air cleaner and duct assembly. - Drain the coolant until the coolant level is below the thermostat. - Remove the crossover exhaust pipe. - Remove the radiator hose from the thermostat housing. - Remove the thermostat housing bolts and clean any sealer from the bolt threads.


(IMAGE: Removing the housing bolts) 725f95f.jpg

- Remove the thermostat housing and gasket. - Remove the thermostat. - Clean the mating surfaces.

(IMAGE: The removal and installation of the thermostat) 0b61938.jpg

INSTALLATION: - Install the thermostat.Install the thermostat housing and gasket.

NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

- Install the thermostat housing bolts and tighten them to 18 ft. lbs. (25 Nm). - Install the radiator hose to the thermostat housing.Install the crossover exhaust pipe. - Install the air cleaner and duct assembly. - Fill the cooling system.

Hope this helps, happy holidays :)

FITTING A CATALYTIC CONVERTER TO FORD FIESTA 1995,WHERE LOCATION?HOW DO WE FIT??


Hi

The catalytic converter is an integral part of your exhaust system - see image below of a typical Fiesta Catalytic converter. There is a variation in the location and design of the converter depending on which engine version you have. I should point out that this is not an easy job for a novice as the exhaust is often solidly rusted at the connecting points and the old converter will require specialist equipment to remove the old connecting bolts.

Also your car will need to go up on a garage lift for this work to be done.

My advise is to bring the car to an exhaust centre to have this work carried out as it is likely to present with a high level of difficulty. See image for reference to what the part looks like.

Hope this helps. Thanks for using FixYa.

Installing 02 sensors


"Up-stream" means before the catalytic converters and are probably in the header pipe(s). The "down-stream" O2 sensors are behind the cats in the exhaust system, usually just behind them. Not the expert here on this particular car but there are probably 4 of these sensors. BMW exhaust systems are very tight on space, be careful tackling this job.
