replace the pcv valve. If it is not working it will allow pressure to build up in the crankcase. this will cause leaks everywhere.
SOURCE: reading coder on toyota echo
I am sorry but no, there are different codes some are P codes, some are B codes, and there are other ones, OBD 1 (84-96) systems could flash the check eng lite and give you codes, but they were just two numbers like 12. A typical OBD 2 code is like this P1546, this is a emission code. Kragen auto or any of the chain auto parts stores will read the codes for free.
SOURCE: Vacuum leak-P0171 2000 Toyota Echo. Need vacuum diagram
A P0171 code does not indicate a vacuum leak; it indicates a dirty mass air flow sensor. This device is located between the air filter box and the intake manifold. Locate it, unplug the wire harness, and remove the 2 screws that holds it onto the intake pipe. Look down inside th sensor, you will see 2 small wires, that are probably covered with fuzzy things...using a spray cleaner, such as brake cleaner, spray the 2 wires until they are clean and shiny. Do NOT use compressed air, that will damage the sensor. When it is clean; reinstall it and drive it. The computer will recognize the now clean sensor, and your troubles will be over.
SOURCE: toyota echo 2000 - airconditioner belt squeaking
well the belt could be loose or the compressor may be seized.....or the belt may be old and squealing.
