Disassembling
Obs erve s crupul ous cl eanl ines s when dis as sembl ing component s, parti cul arly when brake, fuel, air s us pens ion or hydrauli cs ys t em parts are dis as sembl ed. A part icle of dirt or cloth fragment could caus e a s eri ous malfunct ion i f trapped i n t hes es ys t ems .
Blow out al l tapped holes , crevi ces , oil ways and flui d pass ages wit h dry, compres s ed air.
W ARNING: Sui table eye protecti on mus t be worn.
Us e s uit abl e marker i nk to identi fy mat ing parts , do not us e a s cri ber or cent re punch as t hey coul d ini ti at e cracksor dis torti on.W i re or t ape mat ing part s t oget her where neces s ary t o prevent acci dent al i nterchange.Suit abl y identi fy parts which are to be renewed and t o thos e part s requi ri ng further ins pect ion. Keep thes e part ss eparate.To make s ure that t he correct replacement part has been obt ained, do not dis card a part due for renewal unt il aftercomparing i t wit h t he new part.
Cleaning Components
Always us e cleaning agents whi ch are s uit able for the work being undert aken and the component s being cleaned. NEVERus e gasol ine (pet rol ) as a cleaning agent (degreas er). Always make s ure that the component bei ng cleaned is compati blewit h t he cleaning agent.
Always follow the manufact urer's i ns t ructi ons regarding the us e of cleaning agents and make sure t hat t he envi ronment inwhich t he work is being undert aken is s uit able. See Healt h and Safet y Precaut ions for furt her informati on regardi ngcleaning.
General Inspection of Components
All component s s houl d be i ns pect ed for wear or damage before reas s embl ing.
Always make s ure that component t o be i ns pected i s clean and free from oil or greas e.W hen a component is t o be checked di mensi onal ly agains t desi gn s pecified values , use the appropriat e meas uringequi pment i.e. micromet ers , verniers, s urface plates , dial t es t i ndi cat ors (DTI).Always make s ure that all meas uri ng equi pment is correct ly cali brat ed before us e.Reject a component which i s not wit hin specified values /l imi ts or i f it appears t o be damaged.A component may be rei ns t alled if dimens ions obt ai ned during checki ng are at t he maximum t olerance l imi t and itis in an undamaged condi ti on.Bearing journal clearances should be checked where neces s ary us ing Pl ast igauge.

Variable Camshaft Timing Solenoid and Camshaft Position Sensors
ItemPart NumberDescription1-CMP Sens or - exhaus t cams haft2-VCT s olenoid3-CMP Sens or - intake camshaftThe profile, or pos ition and shape of the cams haft lobes are opt imiz ed for a cert ain engine rpm, but this normally limit s low-endtorque or high-end power. At high engine s peeds , an engine requires large amounts of air. However, t he intake valves may clos ebefore all t he air has been given a chance t o flow in. On t he other hand, if the cams haft keeps t he valves open for longer periodsof time, problems st art t o occur at t he lower engine speeds . This will caus e unburnt fuel t o exit t he engine s ince t he valves arest ill open.
To overcome t his , VCT changes t he valve t iming by eit her advancing or ret arding the cams haft s t o allow for opt imum engineperformance, reduced emis s ions, and increased fuel efficiency. This is achieved via an electronically controlled hydraulic s olenoidvalve locat ed in t he camshaft housing at t he rear of t he engine, behind the rear CPS s olenoid. The ECM t rans mit s a signal t o thesolenoid, which direct s engine oil int o t he VCT unit. A valve s pool in the VCT unit regulat es t he flow of oil.For addit ional information, refer t o: Elect ronic Engine Cont rols (303-14A Elect ronic Engine Controls - I6 3.2L Pet rol, Des cript ion andOperation)..
There are 2 CMP s ens ors locat ed in t he camshaft housing. The CMP s ensors monitor the posit ion of the cams haft s t o est ablis hignit ion t iming order, fuel injection t riggering and for accurate VCT cams haft advance-retard t iming feedback.
The CMP sensor is a Hall-effect s ens or, which s wit ches a batt ery fed supply on and off. The s upply is s wit ched when t he t eet h ofthe reluct or pas s by t he tip of t he sens or. The 4 t eet h are of differing s hapes , s o the ECM can determine t he exact pos it ion of t hecams haft at any t ime.For addit ional information, refer t o: Elect ronic Engine Cont rols (303-14A Elect ronic Engine Controls - I6 3.2L Pet rol, Des cript ion andOperation).
