So last night we installed a k24a2 long block into my 05 type-S. We are using the stock k24a2 calibration from Hondata until I get to the tuners on monday. I was told to swap the knock sensor originally out for the knock sensor off of my k20z1.

But now here is my problem. I am kicking out a CEL. Knock Sensor Circuit Malfunction.

So since I'm not using the k20 head should I still be using the k24 knock sensor? Is the sensor swap just if I'm doing the k20/k24 frankenstein? Or is there a way to read the k20 knock sensor on there right now?

We checked and everything is plugged in and nothing is broken. It doesn't even register the knock.

The reason we wonder about it is because I didn't do the k20/k24 swap. I have a strait k24a2 engine and I'm using the base map stock k24 calibration from Hondata. With that said here is a list of the knock sensors

-Knock Sensor
Accord 04-07 Knock Sensor P/N: - 30530-PPL-A01
Civic 03-05 Knock Sensor P/N: - 30530-PPL-A01
CRV 03-07 Knock Sensor P/N: - 30530-PPL-A01
Element 03-07 Knock Sensor P/n: - 30530-PPL-A01
TSX 04-07 Knock Sensor P/N: - 30530-PPL-A01
RSX 02-06 Knock Sensor P/N: - 30530-PPL-A01
RSX-S 02-06 Knock Sensor P/N: - 30530-PRB-A01
Civic Si 06-07 Knock Sensor P/N: - 30530-PRC-003

And the TSX and RSX-S are different so would that ECU calibration be looking for the frequencies of the k24 knock sensor?

Since known of you gave any input or suggestions or help, If for some reason down the road someone ever searches this and has the same problem I had they will now know the answer. I swapped out the RSX knock sensor for the stock TSX sensor and everything is working with no CEL now. We believe this is because we uploaded a stock k24a2 base map calibration from Hondata and it was looking for the frequencies that come out of the TSX knock sensor. If I had a k20 head and uploaded one of their k20/k24 calibrations I'm not 100% sure because I've never done that swap but I would probably then have to use the k20 knock sensor.
