where is the daihatsu terios vehicle speed sensor located

Check tps (Throttle position sensor) to see that it is functioning right. I also had a car that the air flow sensor caused it to stall and loose RPMs. You can buy a spray to clean the air flow sensor.
Hope this helps

freezer side not freezing

Check for ice / frosting inside the freezer .... If present you probably have a defrost problem.... This causes the freezer coil to ice up and block the air flow ... the causes could be a bad defrost heater , defrost timer, defrost sensors, or control board. Also make sure that the condenser coil is clean. remove ALL dust with a vacuum and a coil brush .the coil is located either on the bottom or on the back side of the unit... You didn't give the Make and model #

The possible reason for error is the printer does notread chip on the cartridges.
The reader for chips locate inside the printer bottom ofcartridges.
Take out all cartridges and you see reader it is a small blackplastic which come three contact plates.
Just clean it with compressed air and take out if some contactplate is sedentary.

need to clean massive air flow

There is a special cleaner/solvent needed to clean mass air flow sensor. It can not leave a residual film. You can go to most any auto parts stores & locate it. It will say mass air flow sensor cleaner or safe to use on mass air flow sensors. I know a company called CRC makes the one I use. Just disassemble boots to both side of sensor & unplug wire connector. Clean off both sides of grid & allow to dry. Reassemble.

The sensor it refers to is the density sensor located inside the machine via the right hand door. Open it and clean the large sensor in the middle. If this doesn't work then clean it with a soution and a soft cloth.
