Problem with Code 23 !? (Knock Sensor)

Post by Marlon88 »

Hello.

I just installed my Hondata S300 in my JDM ITR , everything works fine eccept this ... I made the installation as the manual says , I downloaded the ITR base map and I started the car . I noticed that the check engine light came on , I saw that it was a Code 23 and it was saying that it`s the knock sensor . I know that my knock sensor is fine because with my stock ECU everything works fine !!

The check engine light goes off after I switch off the knock sensor from the misc settings and clear the codes .

What`s the problem !?!?!

I can`t figure out what`s setting the code with the knock sensor !!

Here is a pic of the window ..

P28 ECU lacks the electronics to "talk" to the knock sensor. The software is looking for a signal that the ECU cannot provide. You need a USDM P30 or P72 to retain your knock sensor functionality.

Thanks for the reply :wink:

All I have left to fugure out is how to wire up my PLX wideband and where to hook up a switch so I can activate the anti lag .

Thanks
