Four HO2S are us ed by t he ECM t o meas ure t he oxygen content of t he exhaus t gas s es leaving t he engine. Two upst reams ens ors measure t he gas s es before they pas s t hrough the cat al yti c convert er and two addi ti onal downst ream s ens orsmeas ure t he gass es after t hey have pas sed through t he catalyt ic converter.
The HO2S receive a fus ed power supply from t he main rel ay in t he BJB. Each HO2S i s als o connect ed to the ECM on t hreewires which provi de a PW M cont rol of t he s ens or heat ing coil , a ground and a si gnal l ine.
HO2S Preheati ng
The HO2S (oft en referred to as a Lambda (λ) s ensor) only operat es efficientl y at temperatures above 300°C (572°F). Thenormal operat ing t emperature is bet ween 300°C and 850 °C (572°F and 1562°F) and the HO2S is el ect ri cal ly preheat ed s oit reaches t he opti mum working t emperature quickly. Anot her reas on for t he preheat ing is t o mai ntain a normal operat ingt emperature to prevent condens ati on which could damage t he s ensor.
The s ens or heat ing coi l i s a PTC res is tor. The heat ing coil i s s uppl ied wi th bat tery volt age vi a t he main relay and provi dedwit h a ground by t he ECM. W hen t he ECM provides t he ground t he current wi ll pass through t he coil . W hen t he sens or iscol d, the res is tance t hrough the PTC res is tor i s low and a high current wil l pas s t hrough t he coi l. The ECM provi des a PW Mground i ni ti ally. As t he PTC resi st or heat s up t he res i st ance increases reduci ng the current fl ow. Thi s is sens ed by t he ECMwhich graduall y reduces the PW M ground to a cont inuous ground.
The coi l is heat ed immedi ately foll owing an engine st art for a peri od of approxi mately 20 s econds and als o duri ng low loadcondi ti ons when the t emperat ure of t he exhaus t gas s es is ins uffi cient to maint ai n t he opti mum s ens or t emperat ure. TheECM controls t he appl icati on of the PW M s i gnal t o prevent sens or damage due t o t hermal s hock caus ed by the sens orheat ing too quickly. The ECM can diagnos e fault s i n t he heat er coi l and record faul t codes whi ch can be ret rieved us ing aLand Rover approved diagnos t ic s ys tem.
Ups tream HO2S
Two ups tream HO2S are us ed and are l ocat ed in each exhaus t mani fold, between the engine and t he catalyt ic converter.The HO2S compri ses a s ol id el ect rol yt e Zi rconium di oxi de cel l s urrounded by a gas permeabl e ceramic. The output volt agefrom the s ensor i s dependent on the level of O2 pas s ing t hrough t he permeable ceramic coat ing. Nomi nal volt age for λ=1is 300 to 500mV. As t he fuel /ai r mixt ure becomes ri cher (λ<1) t he volt age ri ses t o up t o 900mV. As t he mi xt ure becomesweaker (λ>1) the volt age fal ls t owards 0mV.
The upst ream HO2S i s used by the ECM to monit or t he oxygen content of t he exhaus t gas s es leaving t he engine beforet hey reach the catal yt ic convert er. The ECM wi ll check t he output from the HO 2S to det ermi ne t he combus t ion mi xture andensure λ=1 i s obtained. λ=1 is the opt imum air/fuel rati o which relat es to a mi xt ure of 14.7 kg air per 1 kg of fuel(14.7:1).
The HO2S us es current regul at ion and out put s a linear s ignal dependent on t he rati o of exhaus t gas oxygen to ambientoxygen. The oxygen cont ent of the exhaus t gas ses is meas ured by compari ng it wit h ambient air drawn int o t he HO2S.
Downst ream HO2S
Two downs tream HO2S are us ed and are l ocat ed in the each exhaus t s ys t em after t he s tarter cat alyt ic converter. Thedownst ream HO2S are used by the ECM to moni tor t he oxygen content of the exhaust gass es leaving t he cat alyt icconvert er. The ECM can us e t his i nformati on to check (when the condit ions for catal ys t diagnost ics have been met ) forcorrect operati on of the cat alyti c convert er.
