How do I troubleshoot an error code #9 ??
I have 95 LS/VTEC with an OBD1 ECU, distributor, etc. using a Conversion Harness adapter.
I am using a P28 chipped ECU which is looking for the Knock Sensor signal. This initially triggered a CEL code #23 which corresponds to Knock Sensor, but the car idled very erratically.
In checking it out a friend found out that the plugs were messed up - so we replaced them and the engine sounded much better and revved out pretty nicely.
But now the CEL #9.
What could cause this ??
Thanks for any help.
