i doing a code diagnose on my 1999 civic si ,, is not starting properly ... so i did a diagnose via check engine light and .. it flashes 3 shor ones pause for about 2 sec and it repeats itslef over and over again ....

anyone know what this code means..

thanks

 

Its the map sensor code.

 

thanks ... does that means that is messed up?

 

Either the sensor is messed up, or your vacuum hoses are.

 

i was boosting 11psi without check valves....the car shuted down and now it starts but like if only 2 plugs were firing and is just dumping fuel ...cuase the plugs are wet /... as far as compression is all good .... no blown motor thank god.....

also what is code #30 ??

thanks

 

You sure it was a code 30 ? The accord, odessey and prelude only have a code 30 which is

Automatic Transmission Signal: "A" / SEAF / SEFA / TMA or TMB
defective circuit or unplugged / defective sensor

 

no .. it is code 3......

thanks man
