i just put my h23/vtec together and im getting cel 5,8,9,21. can anyone tell me what these are. 4th gen

 

5: Map sensor
8: TDC sensor
9: CYP sensor(both dist. related)
21:VTEC solenoid

 

would it be because im running h23 dist. instead oh h22????

 

nope, those are interchangeable. Is this a known good distributor, or an unknown?

 

unknown, so if i replace the dist it would fix cel # 8,9

 

If you have an FSM, or a PDF copy on page 11-70 it walks you through a set of procedures to confirm that you have a bad distributor, or if you have access to a known good distributor, you can swap that one and check.

 

well i started my car so does that mean i have a good dist.

More than likely, yes your distributor is good if your car is starting.

Something else is most likely causing those codes and replacing
the distributor will not fix the codes.

 

not necessarily, the engine will run, but if one of the sensors is on it's way out, the ignition timing will probably not be where it should be, so it will run, just not the way it should. Just to cover all the bases you should probably double check the connectors and then do an ECU reset, and see if your code reoccurs.

 

hey thanks for all the help guys i did a ecu reset and the codes went away.
