Dragon, I just replaced one on my Disco II 2003.

There are 2 types, Lucas and Bosch. The Bosch ones have to be soldered and are alot of mucking around. I put the same back on I originally had, Lucas. Hope this helps.

These vehicles are very sensitive to having the exact make when it comes to parts. Many of the aftermarket parts will only create more problems and probably not work. I would certainly get a sensor from the dealership. I have never seen another make of cars be so specific to having the correct parts.

Oxigen sensors ubication for Jaguar 2003, XTYPE, 2.5 motor.


You will find the location of the sensors detailed at http://www.bluejag.co.uk There are two on each side of the engine (front and rear of the engine bay) roughly in the middle half way down the engine and almost at the bottom. The front ones you will be able to see clearly if you remove the battery and tray.

OBD P0134 code - Is this for the pre-cat or post cat sensor?


DTC P0134: Bank 1, sensor 1 refers to the upstream (closest to the engine) sensor. While after market parts will fit, if you put them on an oscilliscope, they don't always show the same wave-form as the OEM part. Ok, OEM is usually more expensive, but at least you know what you are getting.

MY 2003 TOYOTA SEQUOIA GOT ENGINE AND VSC LIGHTS ON. ON THE DEALER, THE COMPUTER READ A OXIGEN SENSOR B1 S1Y GOT THE PART, I NEED TO KNOW HOW TO INSTALLED AND WHERE IS LOCATED.


That model Sequoia should have four oxygen sensors. There will be two in each exhaust line. One will be in front of the catalytic converter, and one will be behind it.

B1 should mean bank one. This is the driver side. S1 is probably the oxygen sensor located before the catalytic converter; however, I am not certain of the number sequence here.

The sensors screw into the exhaust pipe. They will have wires coming out the top.

My 2003 range rover hse came back with a code p1107 - front heated os sensor was basically stuck. I wanted to purchase the o2 sensor from an aftermarket site but did not know the exact part I should get....


Look at the left and right exhaust manifolds for your front o2 sensors they will be before your converter and to get the right one measure the wire from the sensor to the connector thats your length, also if yours has two front o2's go ahead and replace both since the front o2's do most of the work.

WHICH O2 SENSOR HAS THE HEATER CIRCUIT IN IT BEFORE OR AFTER THE CATALYST


Hi.
The Oxigen sensor are in diferent kind.
1 -- With a single wire. " is only oxigen sensor"
2 -- With 2 wires " is only oxigen sensor"
3 -- With 3 wires " Is oxigen and heater sensor"
4 -- With 4 wires " is oxigen sensor and heater sensor.
5 -- with 6 wires " is oxigen, heater A/F sensor" normally Nissan)

OK........Your question.
Depend of the year of your car.
But all the car they are Bank 1 or single bank. Engine in line
4 cyl . or 6 cyl. And are identified sensor 1 bank 1 and sensor 2 bank 1. S11 or S21.
But all the Engines in V are bank 1 and bank 2.
Sensor 1 bank 1, sensor 2 bank 1, S11 or S21.
Sensor 1 bank 2, sensor 2 bank 2, S12 or S22.
Sensor one is alway before catalystic.
Sensor two is alway after catalystic.

If you have problen with the oxigen sensor you need to put a scanner to see the number of code, The number of code will give the especific sensor that you need to replace.
The code can be heater or oxigen. and can be refer to a the same sensor.

I hope this information work for youu.
Thank you for use fixya.
