code9 trouble

Post by redlude1991 »

My 91 Si 4ws is showing code9. I replaced the cal sensor, but still the same code. What is going on with it?

You may want to check your wiring. Perhaps your ECU isn't getting a signal from the sensor even if the CYL sensor is good.

You can also try completely resetting the ECU (pull the ECU fuse under the hood for 60 seconds) to see if the code clears.
