Crank sensor is the same as crankshaft position sensor - location is most likely inside your timing cover ... you can only clean if you take out all the pulleys. don't bother with this one.
Exhaust gas temp guage - you do not have this in your car.
MAP sensor and mass air flow are similar, you will have a MAP sensor in your car - location is on the intake manifold ... take out your air cleaner box and you'll see a sensor with 3 wires labeled map. take it out and clean it - make sure the rubber o-ring is not stretched ... if it is then replace before you put it back in after clean ... clean using carburator cleaner bottle only do not use petrol.
nitrogen oxide sensor - you do not have this in your car.
oxygen sensor - you might have this on your car, location - on the exhaust pipes, size 22 spanner required to open it - if you have it open and clean.
throttle position sensor is located on the throttle body ... this sensor doesn't require cleaning ... instead you can open up your throttle body and clean it ... you'll find another sensor on the throttle called the idle air controller - open that system up and clean it up ... good for the car ... when you open the throttle body you'll find 2 rubber pipes going into the throttle. be sure to let the car cool down before you open ... those pipes carry coolant and have hot water running through them... so make sure engine is cold when working on this one...
if you run into any troubles let me know .. i'll help you out.
good luck.
