The s ens or is a Negat ive Temperat ure Co-efficient (NTC) thermis tor element . The element res is t ance decreas es as thes ens or t emperature increas es. The ECM suppli es the sens or wit h a 5V reference volt age and a ground and meas ures theret urned s ignal as a t emperature.
The ECT s ens or is important to the correct running of t he engi ne as a richer mixt ure i s required at low engi ne cool antt emperatures for efficient s tarti ng and s mooth cold running. As t he engi ne cool ant temperat ure i ncreas es , the ECM usest he temperat ure si gnal from the sens or to l ean off t he fuel mi xt ure to maint ai n optimum emis s ions and performance.
The ECM moni tors the ECT sens or for faul ts and can s t ore faul t rel at ed codes . These can be ret ri eved us ing a Land Roverapproved diagnos t ic s yst em. If the ECT sens or fail s, t he ECM us es a defaul t val ue of 90°C (194°F). The electric fan cont rolmodule i s s ent a default coolant temperat ure val ue of 105°C (221°F) and s wit ches t he cooling fan on permanent ly.
Engine Oil Level/Temperature Sensor
The engi ne oil l evel/t emperature s ens or is locat ed on t he unders ide of t he engi ne and is secured i n t he engi ne oil pan wi th3 s crews and i s s eal ed wi th an O-ring s eal. The ECM suppli es the s ens or wit h a 5V reference volt age and two wires s uppl yt he temperat ure and oi l level si gnal s back t o t he ECM.
Two t ypes of engine oi l level /t emperat ure s ensor are us ed. On earli er model s a capacit ive oi l level s ens or i s fit ted and wasrepl aced by an ul trasound l evel s ens or on l at er models . The principl e of the temperat ure s ens or i s t he s ame in bot h s ens ort ypes . The sens ors can be i dent ified by di fferences in t he s ens or housi ngs ; t he capacit ive s ensor has t he electricalconnector moulded s quare t o t he bas e of the s ens or, t he ult ras oni c s ens or has the connect or moulded at a s li ght angle tot he bas e of t he s ens or.
The ECM us es both the oi l l evel and t emperature s ignals t o calculat e t he oil level. Temporary oil level changes caus ed byhil l driving or cornering are taken i nt o account by t he ECM us ing addit ional informat ion s uch as vehi cl e s peed and engi neload.

The engi ne oil l evel s ens or compris es t wo capaci ti ve gauge el ement s . Thes e meas ure the resi s tance to elect rical currentpass i ng through t he engine oi l.
There are t wo capacit ors , one meas uring t he permit ti vi ty of t he oil and a second with t wo pl at es s et verti cal ly meas uri ngt he hei ght . The s econd capaci tor wil l have a proport ion of oil and ai r bet ween t he plates and s i nce t he permit ti vi ty of ai r isdifferent t o t hat of oi l, t he permi tt ivit y readi ng wil l change as t he level of oi l decreas es and the ai r between t he plat e gapincreas es. This permi tt ivit y readi ng is compared t o t hat of the oi l (t aken by t he first capaci tor) and an oil level is derived.
Engi ne Oi l Level Sens or - Ult ras ound Type

The engi ne oil l evel s ens or us es an ult ras oni c puls e, which is refl ect ed back from the s urface of t he oil . The ti me i t takesfor t his s i gnal t o ret urn t o t he s ensor i s turned int o a PW M s ignal and is s ent to the ECM. The ECM det ermi nes the ti met aken for the ul trasonic pul se si gnal t o be recei ved and calculat es it i nto an oil level fi gure.
Engi ne Oi l Temperat ure Sens or
The engi ne oil t emperature s ensor i s a Pos it ive Temperat ure Co-effi ci ent (PTC) thermis t or el ement . The element res i st anceincreas es as t he sens or temperat ure decreas es. The ECM s uppli es t he sens or wit h a 5V reference vol tage and a ground andmeas ures t he ret urned s ignal as a t emperature. A low oil temperature wil l res ult in a l ow volt age bei ng ret urned t o t heECM and hi gh oil temperature wil l ret urn a hi gh volt age reading.
The ECM moni tors the engine oi l level/temperat ure sens or for fault s and can s tore faul t rel at ed codes . These can beret ri eved us i ng a Land Rover approved diagnos t ic s ys tem. If the sens or fail s , the ECM us es t he engine cool ant temperat ures ens or s ignal val ue as a s ubst it ute.
Manifold Absolute Pressure (MAP) Sensor
The MAP s ensor i s located i n t he lower part of t he int ake manifol d. The MAP s ens or meas ures t he abs olut e pres s ure in t heint ake manifol d. The sens or is a semi -conduct or type s ens or which responds t o pres s ure acti ng on a membrane wi thin thes ens or, al tering t he output volt age. The s ens or receives a 5V reference vol tage and a ground from t he ECM and returns as ignal of bet ween 0.5 - 4.5V t o t he ECM. A low pres sure ret urns a low vol tage s ignal to the ECM and a high press ureret urns a hi gh volt age.
The MAP s ensor det ect s quick pres s ure changes i n t he int ake mani fol d aft er the el ectri c thrott le. The s ignal is us ed inconjunct ion wi th the MAF sens or si gnal t o calculate the injecti on peri od.
The ECM moni tors the engine MAP s ens or for faul ts and can st ore fault related codes. Thes e can be ret ri eved us i ng a LandRover approved diagnost ic sys tem. If t he s ens or fai ls , the ECM uses t he MAF/IAT s ensor s i gnal value as a subs ti tut e.
Electric Throttle
The electric t hrot tl e is locat ed at t he entrance of t he int ake manifol d and is secured t o t he manifold wit h four Torx headbolt s. The t hrot tl e als o provi des for t he connect ion of t he air cleaner hous ing out let pipe which is secured t o t he t hrott lebody wit h a cl ip.
The electric t hrot tl e compri ses t he t hrott le body, a round throt t le di sc whi ch is act uat ed by a damper mot or and a thrott leposi ti on s ens or. The el ect ri c thrott le is control led by the ECM and recei ves pos i ti onal s ignals from the TP s ens or. If afai lure of the mot or occurs , t he thrott le di s c is returned to it s cl osed pos it ion by the s prings, wi th li mit ed engine s peedavai lable to the driver.
Spindle Damper Mot or
The mot or i s a DC damper motor which drives a gear wheel and t wo s pri ngs ; one for opening and one for cl osi ng. Themot or rotat es the spi ndl e t o which t he t hrott le dis c is at t ached. PW M s i gnals from the ECM control the damper mot or t oadjus t the pos it ion of t he t hrott le dis c, regul ati ng the amount of air ent ering the i nlet manifold for combus ti on.
Movement of t he mot or is achieved by changing t he polarit y of the power s uppl y to the DC mot or, all owing i t to beoperated in bot h direct ions . The throt tl e dis c and t he mot or has two maxi mum pos it ions ; t hrott le di s c cl osed which all owsmi ni mal air flow t hrough t he electric t hrot tl e int o t he int ake manifol d and t hrott le dis c open which all ows maximum air flow

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.
