Front and Rear Knock Sensor Differences

Post by SC-Type »

Are there any for an SII L67?

I was in the mist of trying to connect the rear one (between engine and tranny) and noticed that the connector won't fit in the sensor. The front is definitely a smaller connector when compared to the rear. Are the sensors actually different in any way? I cannot seem to find any different designation on rock auto or ebay.

I am hoping that I don't have to remove the sensor and that I can simply replace the rear connector for a front connector and be done with it.

No differences at all. The rear sensor has an extension on it that makes it easier to connect, and even it is a plugin.
2005 GXP - White Gold Pearl, no mods...yet.
2000 SSEi - Resurrection in progress. Built L67 w/L32 fuel rail, ported heads, and cam. Camaro front brake system, GXP cluster, and much more in planning.

ummm, never noticed an extension while removing the harness. I'll check my pile of wires and see if anything in lingering. That would make sense because originally the wire was too short, so I ended up extending it. I thought it was too short because of the routing I chose for the main harness, but the extension makes sense. And it'll also explain why the connector doesnt want to insert into the sensor.

Thanks!

I had the same problem. Except I removed the sensor and cut off the connector before I figured it out.
