Anyone ever had to replace a knock sensor on there 02 srx? I just hooked mine back up and the coolant light flashes 6 times then starts over. Telling me it's the knock sensor.
Check the wiring to the DCS sensor especially around the connector. I have found the DCS sensor wire to be quite inflexable and succeptable to breaking.
If you are already aware of an issue with the wiring, cut the section out that is damaged, solder in a new section on the sensor side of the wiring [don't use cheap crimps] and see if you still have the same issue. If the sensor still is acting up replace it.

I also had that same exact issue 2 years ago with same 6 flash sequence. It was intermittent and was a broken dcs wire for me as well. It broke right near the center cylinder.
