H2o bank 2 sensor 1 location

a location HUNT AGAIN AND NO USEFUL FACT TOLD.
V6 OR V8 NOT TOLD
no country told at all, yes year, 2005,
The LR3 name was chosen for North American and Middle Eastern markets(wiki facts)
USA IS 4.0V6 AND 4.4V8 GAS ONLY


no engine size told or fuel it burns.
Land Rover LR3 HSE?
what engine, no VIN told and engine code is in 8th digit of VIN
well bank 2 is the bank that does not have cylinder #1
and all V6 (V_n) the cylinder 1 most front, off set. to the front.
the front means nearest crank pulleys.

Discovery 3 / LR3 (2004-2009)?

3 engines LR3 and one 2.7L diesel, so is it gas or diesel>
v6 or V8 and not told. and is and engine 100% questions.
WANTS 2 CMP SENSORS OR JUST 1.?

4.0 L Cologne V6 (petrol) CAM CHAIN HERE LOVE TO FAIL SO IS NOT BAD CMP ITS CHAINS, I BE, EVEN AT 50K MILES FAILS.
4.4 L AJ41 V8 (petrol) BANK 2 IS LEFT (DRIVERS PERSPECTIVE)
RIGHT IS #1 BANK AND CYLINDER



V8
2 CMP
LEFT BANK, TOP LEFT INSIDE OF VALVE COVER. BANK2
RIGHT BANK , TOP FRONT OF VALVE. COVER, BANK1

FIRST GOOGLE HIT. ! V8, CMP BANK2
BUY AND READ THE SERVICE MANUAL IS BEST IT MAY NEED LEARNING MODE ACTIVATED.

Locate your number1 cylinder that's a your bank 1
opposite side after the catalytic converter is your bank2 sensor 2

Bank 2 is the opposite bank from the engine bank that contains number 1 cylinder.

o2sensors are located in the exhaust system.you have 4 o2sensors on your car.so you need to know which sensor your looking for.bank 1 sensor 1 is the first sensor in the exhaust pipe on the side cylinder 1 is on.bank 2 is on the side cylinder 2 is on.then you have a sensor before the catalytic convertor and one after the convertor.

What motor? Bank refers to the side of the engine. Bank 1 is always the same side as the numb one cylinder. Bank 2 is the other side. Sensor refers to before or after the catalytic converter. Sensor 1 is before the cat. Sensor 2 is after the cat. If you have any questions let me know. Thank you for using fixya.com!

O2 sensor locations break down like this.

The bank refers to which side of the motor. Bank 1 is always the same side of the motor as cylinder number 1. Bank 2 is the other side of the motor.

Sensor refers to before or after the catalytic converter. Sensor 1 is always before the cat and sensor 2 is always after the cat.

So bank 2 Sensor 1 would be the O2 on the passenger side of the motor before the catalytic converter. You should see it threaded into the exhaust manifold.

sensor 1 is the first 02 sensor in the exhaust.bank 2 is the side of the motor that cylinder #1 is NOT on,in this case bank 2 would be on the passenger side(right side) of the motor.which means the first 02 sensor in the exhaust on the passenger side of the motor

This all depends on what size engine you have in this car, but it goes this way bank 1 is the side of the motor where #1 cylinder is, some cars have three , four or two sensors depending on the year and make and engine size, i will draw a graph to try and help, for example a sensor located in bank 1 sensor 1 would be the sensor on # 1 cylinder side of motor and closeest to engine before the converter, then if it was bank1 sensor 2 then the sensor would be located on the same side the #1 cylinder was but this one would after the converter in exhaust, then if it was bank 2 sensor 1 then sensor would be on the otherside of exhaust where # 2 cylinder would be and that one would be before the cat closest to motor, and then bank2 sensor 2 is the same side as #2 cylinder but after the converter. bank 1 = #1side / bank 2= #2 side/ sensor 1 =before cat/ sensor 2 = aftercat. hope this is helpful.

A code P0155 may mean that one or more of the following has happened:
* O2 Heater element resistance is high
* Internal short or open in the heater element
* O2 heater circuit wiring high resistance
* open or short to ground in the wiring harness

Possible Solutions:
* Repair short or open or high resistance in wiring harness or harness connectors
* Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)


Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

Some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Hope helps (remember to rate this).

Bank 1 is the same side as cylinder #1 and bank 2 is the same side as cylinder #2. Good luck and hope this helps.
