5 Lucas Lambda Sensors Lambda Sensors "brought up-to-date" Lambda Sensors "the story so far..." Over recent years vehicle engine management technology has had to move on, in order to keep up with changing EU Air Pollution Laws. As a consequence Lambda sensor technology has also moved on, which means that the humble Universal Lambda sensor is not so universal any more. With the introduction of ODB, EOBD II engine management systems and Direct Injection petrol engines, it has become necessary to fit a more sophisticated Lambda sensors in the exhaust system. On post 01/00 engine management systems there are two sensors fitted in the exhaust system, one located either side of the catalytic converter. The first sensor in the exhaust system is the regulating Lambda sensor. This sensor is also known as the pre cat sensor or the up stream sensor. The second sensor, which is located after the catalytic converter, is the diagnostic sensor, also known as the post cat sensor or the down stream sensor. ECU Engine Pre Cat. Sensor Post Cat. Sensor Catalytic Converter These sensors are the next generation of sensors and fall into two families. The first type is a Planar sensor and the second type is a UEGO sensor, with 5 or 6 wires. These sensors were developed so the ECU can more accurately meter the fuelling of the engine. These new generation Lambda sensors were first fitted from about January 1996 until it was made compulsory in January Vehicle applications fitted with these types of sensors need a dedicated, direct fit replacement sensor, with the same technical specification as the one removed. Therefore universal Lambda sensors will not work properly on these types of engine management systems and should never be fitted. So supplier beware*. To this end, this Catalogue has been compiled to help you, the aftermarket supplier, establish which sensor is required to do the job right and first time. 3

6 Lucas Lambda Sensors Why OE specific over Universal There are two main types of Lambda sensor: Universal It was once generally accepted that seven part numbers would fit 95% of the vehicle parc. Which meant a low stockholding with maximum return. Not so true any more as vehicle technology has moved on and universals will not work on any vehicles produced today. OE Specific Designed to match the OE in fit, form and function. The benefits are simpler to fit and reduced fitting time. The downside is a greater stock inventory is required just to cover the same percentage of the vehicle parc. Today's OE sensors are more technically specific with quicker light off times. There are two main types of Lambda Sensor Great care must now be taken when identifying Lambda sensor's, as more and more sensors are becoming vehicle specific. Colour codes are crucial to getting the job right. European Lambda sensor wire colours generally follow the same rules ZIRCONIA TITANIA Black = signal wire Red = heater + Grey = dedicated earth wire White = heater White = heater wire Black = signal White = heater wire Yellow = signal + All Zirconia sensors have a 18mm thread and the Titania sensors can have either 18 mm or 12 mm threads with a red wire. Planar Sensors, which are in the Zirconia family, have no identifying colour changes to the wires. The main differenceis to the probe that goes into the exhaust system, fundamentally it has abigger wattage heater so will bring the sensor to full operating temperature quicker. These sensors will not have a compatatible universal replacement. 4

7 Lucas Lambda Sensors Difference between Zirconia & Titania Zirconia Zirconia sensors have an 18mm thread size. Zirconia sensors generate a voltage, this voltage will be low if the air / fuel mixture is lean (high Oxygen). If the mixture is rich (low Oxygen) the voltage will be higher. The range is between 0 and 1 Volt. Titania Titania sensors have a 12mm or 18mm thread size. Titania sensors have a voltage supplied from the ECU (electronic control unit) and the sensor varies its resistance in relation to how much oxygen is in the exhaust. To identify this type of sensor, one of the wires is generally Red and the sensors look smaller.

8 Lucas Lambda Sensors Lucas Universal Lambda Sensor You should be aware that there are two basic types of Lambda Sensor. Zirconia which is the most common type and Titania. The four wire universal Zirconia sensors were not so universal from 1997 onwards and unusable after January The two product types are not interchangeable, we suggest you use the Quick Check List and chart opposite, to establish the correct replacement type. Zirconia Type Standard European Colours BLACK WIRE GREY WIRE Is the signal connection. Should be connected to Earth. WHITE WIRES Should be connected to the heater. These wires are not polarity sensitive so you can connect them either way round. Non European sensors may have different colours see the check list Quick Check List 1 Check the year of the car 2 Count the number of wires on the original sensor. 3 Check the colour of the wires. a) See check list opposite b) If the sensor has one red wire it may possibly be a Titania sensor.

11 Lucas Lambda Sensors Lucas Technical tips Lambda sensors, unlike other types of sensor fitted to an engine, have an optimum performance life cycle, which generally lasts about to thousand miles. The decrease in performance happens gradually to a point where the sensor will become tired or lazy. The sensor still works but the reaction times are slow. Regular drivers of the vehicle will not notice this change. Testing a Zirconia Lambda sensor off the vehicle is quite easy, all you need is a vice or a similar means of holding the sensor, a propane torch and a high impedance digital multimeter. Test using a four wire Zirconia sensor WARNING When using propane torches remember to read and follow the manufacturers safety instructions First check the general condition of the sensor if there is any sign of damage change the sensor. Now test the heater circuit for continuity, if the heater has failed change the sensor. now connect the voltmeter red probe to the signal wire (generally black) and the black probe to the earth (generally grey) and set voltmeter to.000 volts. Then with a propane torch heat up the tip of the sensor until it is cherry red. The sensor should give off a reading of nearly 1 volt in a few seconds. If it takes longer than 20 seconds to get a reasonable reading change the sensor. In the case of a 1 or 3 wire sensor the body of the sensor is the earth. (For wire colours see chart). There is only one test you can do on a Titania Lambda sensor off the vehicle and that is to test the heater circuit for continuity. The best way to test these sensors is on the car with an oscilloscope. The signal should switch between 0-1 volt and 0-5 volt, depending on the range of the sensor. One of the most misdiagnosed reasons for changing a Lambda sensor is when the vehicle fails an MOT on the emission test when the Lambda reading ( ) is high. This is not a measurement of the Lambda sensor but a calculation of the burn. High Lambda in this case is too much oxygen in the exhaust system; usually a pinhole in the exhaust after the Lambda sensor. Check if the exhaust is in good condition or has had any part replaced recently, and this will be the most likelly cause, not the Lambda sensor. ϒ 9

12 Lucas Lambda Sensors Lambda Sensor visual check On removal of the Lambda sensor first inspect its condition. Any sign of damage to the body, wires or the plug you should change the sensor. If you are replacing the engine for what ever reason you should always change the sensor as well, likewise if you have to replace the Catalytic Converter for any reason always change the Lambda sensor as well. ANTI-FREEZE CONTAMINATION In the event of a leaking or blown head gasket anti-freeze contamination will damage the Lambda sensor. RICH FUEL MIXTURE Rich running problems or engines that are burning oil will lead to the Lambda sensor getting fouled or clogged up. SILICONE POISONING Using fuel additives or lubricants that contain silicone in will damage the Lambda sensor. In all these cases the Lambda sensor must be changed! 10

13 Lucas Lambda Sensors Lambda sensors a common misunderstanding When a modern petrol vehicle goes for an MOT it will have to undergo a Catalyst test. This is to measure the emission output of the engine and the efficiency of the catalytic converter. The test process consists of two parts; a natural idle reading and a forced idle reading (at approximately 2500 rpm). Before the test can begin the engine must reach a required temperature, this is measured by inserting a temperature probe into the oil via the dipstick tube. When the required temperature is reached the emissions probe is then inserted into the tail pipe of the exhaust. This probe measures four gases, hence the name four analyser; they are CO, CO 2, Hydrocarbons and oxygen. There is a fifth reading on the print out this is the Lambda reading. Any of these five readings can fail an MOT test, but this fifth reading is the most commonly misunderstood part of an MOT emissions failure print out. The Lambda reading, on the printout, is a mechanical calculation of the four gas outputs. This is to determine the efficiency of the combustion. It is not a measurement of the condition of the Lambda sensor. This misunderstanding occurs mainly when the four readings show a normal or pass state and the fifth reading shows a high Lambda value. The most common interpretation of this is a failed or defective lambda sensor. The reading actually indicates that there is two much oxygen in the exhaust gas after the lambda sensor. Why after the Lambda sensor, if it was before the Lambda sensor it would be picked up and the fuelling would be altered accordingly. Combustion Gases Lambda Sensor Oxygen Leak Exhaust Probe How do we explain the extra Oxygen?. Exhaust systems in good condition, when in operation, have negative pressure inside them. So all it takes is a small pinhole to appear on the system to allow air to be drawn in and because of the negative pressure no exhaust gas is blown out. So the exhaust sounds in good condition. Another reason is a new piece of exhaust has recently been fitted. It may be a joint has not been fully sealed or there is a small imperfection in the welding, either can allow oxygen in to corrupt the reading. 11
