so im throwing codes like i said they are the map sensor , Vss , vtec spool solenoid, and knock sensor, the knock one sounds pretty not cool

any idea what exactly all of these mean?

 

3 is your MAP sensor electrical problem and 17 is the VSS or car speed sensor.

dont hold me responsalbe cause i dont have these codes, but I think 21 is your VETC solonoid and 23 is the VTEC oil presure sensor.

 

21 is the vtec spool solenoid valve and 23 is the one im worreid about its the knock sensor and im not sure what that is

 

look at my avatar <--- that's waht i'm doing now! i didnt see u knew what the codes were.

The knock sensor is on the back of the head and detects things like detonation, preignition, and other harmfull-things-to-the-engine symtoms.

 

my car is turboed so this is why it scares me

if one of those many things occured once or twice would the code still be on the ecu or will it clear off?

 

Getting the code means that there's a problem with the sensor, not that your getting detonation,etc.., check for bad grounds or lose conections.

is your car a OBD0 or 1? i need to know for your last question

 

this is what the knock sensor looks like. on the fierwall side of the head(rear) just below the intake manafold.
