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.

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 .

Seat belts

Seat beltsPRINCIPLE OF OPERATION
Seat belts Seat belt safety
WARNINGS
Seat belts are designed to bear upon
the bony structure of the body, and
should be worn low across the front of
the pelvis, or the pelv is chest and shoulders,
as applicable; wearing the lap section of the
belt across the abdominal area must be
avoided.
Seat belts should be adjusted as firmly
as possible, consistent with comfort,
to provide the protection for which
they have been design ed. A slack belt will
greatly reduce the protec tion afforded to the
wearer.
Care should be taken to avoid
contamination of the webbing with
polishes, oils and chemicals, and
particularly battery acid . Cleaning may safely
be carried out using mild soap and water.
The belt should be replaced if webbing
becomes frayed, contaminated or
damaged.
It is essential to replace the entire
assembly after it has been worn in a
severe impact even if damage to the
assembly is not obvious.
Belts should not be worn with the
straps twisted.
E82942
Do not carry hard, fragile, or sharp
items between your person and the
seat belt. In an impact the pressure
from the seat belt on such items can cause
them to break, which in turn may cause death
or serious injuries.
Each belt assembly must only be used
by one occupant; it is dangerous to put
a belt around a child being carried on
the occupant's lap.
The occupants of the front seats
should not travel with the seat back at
more than 30 degrees from upright.
Doing so will reduce the protection afforded by
the seat belt.
WARNINGS
Seat belts should be worn by all
vehicle occupants, for every journey
no matter how short. failure to do so
will greatly increase the risk of death or
serious injury in the event of an accident.
No modifications or additions should
be made which prevent the seat belt
mechanism from taking up slack, or
prevent the seat belt being adjusted to remove
slack. A slack seat belt offers a greatly reduced
level of occupant prot ection in an impact.
If any damage, wear, cuts, defects, or
impaired operation are noted with the
seat belts, the vehicle should be taken
to a Land Rover Dealer/Authorised repairer for
immediate attention. Do not use the vehicle if
the seat belts cannot be operated correctly.
When using seat belts to restrain items
other than occupants, take care to
ensure that the belts are not damaged,
or exposed to sharp edges.
