Ntk Lambda Sensor

NTK 4 wire Oxygen Sensor ( Made in Japan by NGK) NGK # 21027 NTK # 11984 ( It is a heated Thimble Zirconia Ceramic Oxygen sensor with Isolated Ground and (5-7 OHM) resistance between the two heater wires) This will replace 95% of the 4 wire oxygen sensors on cars made before 1998. And 87% of the 4 wire oxygen sensors made after 1997. It will not replace the TITANIA sensor and is not the best replacement for the PLANAR 4 wire sensor.If you have a RED wire on your oxygen sensor it is a RED FLAG that your sensor is a TITANIA sensor, which is completely different than all other sensors and is used on less than 3% of cars and trucks.The PLANAR Sensor starts working within the first 30 seconds of start up while the sensor I have starts working within the first 60 seconds. This is becoming a more popular sensor to combat pollution during the first 30 seconds of staryt up and was first put into use in 1998 on the VW Beetle and is used on about 15% of the cars made in the last two years The ohm resistance between the two heater wires is between (12 and 17 OHM) The sensor I have listed here is the same basic sensor as the Bosch 15734 or 15732 Universal Sensor , the Walker 250-24000 Sensor and the Denso 5010-100824. You will have to splice the wires into your old oxygen sensor harness, and I have a some instructions I'll throw in on the deal, along with 4 butt connectors and 4 pieces of shrink tubing and some 8 inches of insulating sheathing.Most of the newer cars and trucks made in the last 10 years have more than one sensor, to compare emissions before and after the catalytic converter and right and left bank on v6 and v8 engines. It is a good Idea to replace them all at the same time. so you don't get mixed readings to your computer.Winning bidder pays 3.85 for US Priority Shipping for one and 1.00 additional shipping for each additional sensor----------------------------------------------------------------------------------------------------------------------- This Oxygen sensor has the standard 18 millimeter 1.5 thread pitch thread which fits 98% of the systems out there. If you damage the threads removing the old oxygen sensor a 18mm spark plug thread chase will do a nice job of cleaning the threads.This sensor has 4 wires 2 white wires for the heater (polarity doesn't matter)1 black wire is the signal wire to the ECU (computer)1 gray wire is the isolated Ground which can be attached directly to the chassis if you would like to use it to replace a 1, 2, or 3 wire setup .BELOW IS MORE INFORMATION ON THE SENSOR AND IT'S APLICATION. Tech info - NTK Oxygen Sensors (A division of NGK)NTK is the world's leading supplier of OEM oxygen sensors, supplying more vehicle makers with oxygen sensors than any other manufacturer. NTK oxygen sensors are individually tested to ensure the highest level of quality and reliability.Everyone agrees the amount of pollution produced by motor vehicles should be reduced. In order to encourage reduced emissions governments have progressively introduced tougher exhaust gas emission legislation. Since 1981 the majority of cars and light trucks built throughout the world have been equipped with oxygen sensors. NTK oxygen sensors continuously detect the composition of exhaust gases. As the output from the sensor changes the ECU instructs the fuel mixing system to alter the mixture. This ensures the air/fuel mixture is always correct and promotes catalyst efficiency.A new NTK oxygen sensor can help lower emissions, improve fuel mileage, improve engine efficiency and extend catalyst life.NTK oxygen sensors are OEM approved and are built with the highest quality materials and craftsmanship to ensure superior quality for your automobile. NTK oxygen sensors meet or exceed original equipment specifications.Rely on the World Leader in sensor technology NTK.PLEASE read the instructions and check the different color combinations listed below before cutting any wires !1- Remove old sensor from vehicle using a o2 sensor socket or 22 mm wrench. You may need to depress a plastic tab to disconnect the plug connector from the main harness.2- After removing the old sensor from the vehicle place it side by side with the new sensor. Mark the wires of the old sensor so that when the plug end is spliced to the new sensor the overall length will be the same or slightly longer than the older old sensor. I prefer to make a staggered cut where each wire is 1.25 shorter than the next wire, so that each but splice connector is not next to another connector and when shrink tubing is placed over each butt connector it would still allow the included silicone/fiberglass sheathing to slide over the spliced harness.This means the longest wire on the harness plug end is the shortest wire on the Sensor End and so on. It is a little more work but leaves a much nicer finished product.3- Once you have cut them to the right length, strip the insulation 1/2 inch from the end and twist the wire end and fold over in the middle to double the thickness. This greatly improves the crimp connection ( a solder joint is a great way to go too.4- Place the 4 pieces of shrink tube one over each wire and the 8 inch length of included insulation over the old harness .5- I prefer the dimple style of crimping tool for a good crimp , I like to use 4 crimps per connector. One on both side of center of the metal Butt connector and one on each end of the all plastic end. Hope this doesn't confuse, it's just something a old timer taught me 20 years ago.6- Now slide the shrink tube over each butt connector and use a hair dryer or other heat source to shrink the tubing.7-Now slide the 8 inch length of sheathing over the butt connectors,you can tape the ends or zip tie or both.8-Reinstall the new oxygen sensor in reverse order of removal. Thre is an antiseize compound factroy applied to the threads of the oxygen sensor.Your Done and have saved a couple hundred Bucks! Congratulations! PS: If your car has a fault light on it may need a test drive to turn it off , though on some cars it requires disconnecting and reconnection the battery ground cable for 10 seconds.And yet others require a scan tool to turn off but that is less common.Note the colors of the wire are for the wires connected to the sensor between the sensor and the connector it is attached to. The main harness on the car after the connector is diferent from manufacturer to manufacturer and model to modeland I have no conversion for them.If you have other wires on your sensor here are some color conversion options:1 - Case Number One2­-Wire Oxygen Sensor OLD NTK Blue to Black White to Gray 2 - Case Number Two4-Wire Oxygen Sensor OLD NTK Blue to Black White to Gray 2 Black to 2 White 3 - Case Number Three4-Wire Oxygen Sensor OLD NTK White to Black Green to Gray 2 Black to 2 White 4 - Case Number Four4-Wire Oxygen Sensor OLD NTK Green to Black Yellow to Gray 2 Black to 2 White WARNING do not try installing if you do not see the color combinations listed , email me first !Below is a list of cars and trucks using the PLANAR Sensor which is NOT compatible with this 4 wire sensor I have listed.1998: VW 2.0L New Beetle 1999: Cadillac Catera, Saturn 3.0L LS, VW 2.0L Jetta 2000: All Audis exc.
