My 99' B18b1 teg is flashing cel code 9.
Its said that the code is:
CYP Sensor (Cylinder) defective circuit or unplugged / defective sensor
* invalid code for throttle body injection Hondas
** invalid code for V6 engines

Where is this sensor and how 'critical' is this problem?
I havent noticed any performance decreases, but I would like to get this problem fixed as soon as I can.
I would appreciate any help!


Thank you very much!

i believe its in the dist. try resetting ecu to see if it comes back

 

thanks for the reply!

Yea, i've tried resetting the ECU... The light usually comes back ~2-3 days after with ~150miles of driving. I've taken off the distributor housing (cap) and wasnt able to get any further because i wasnt able to take off the rotor.. But should the light turn off if the problem is solved? or do i have to always reset the ecu?

Thanks

 

You sure its not cel code 90. Gas cap integrity might be lost.

 

hmm.... you have a good point there.... Im on OBD 2
I wouldent know how to read 90 when the light flashes...
so it might acutally be
How would i know that its 90 instead of 9?

:hopeful:

 

It would flash slowly if its 90 and fast if its 9. You can't really compare though. If you have an autozone near you, they will check the code for free.
