Have a B16A JDM with Type R head in a 90 hatch. Has been running great for about a year and now is throwing a code - 2 long blinks and 3 quick blinks, so I think that means 23.. when I looked it up it refers to the Knock Sensor... I have tried reseting the ECU and it will still pop up after a few minutes of driving.

What should I do or check? Have always used 87 oct. gas..:confused

BUMP

Okay, I have tried adding an additive to the fuel and went to a full tank of 89 Oct gas and reset the ECU.. The light still comes on with a 2 blink and 3 blink -fast, so I am guessing it is still the knock sensor...

Any thoughts? as this is the first time this has happened in over 3 years of flawless use.:cry
