I have collected 14 different sensors for testing and have only found
the DR number or in the case of a Quad 4 10456209 number.
The last 4 digits are the date code. Usually the year and day of
manufacture (Julian Calendar). I have profiled the sensors by getting a
1/4 NPT pipe coupling and screwing one sensor in one end and another
sensor in the other end. I set up with 2 DR562 sensors. I applied
a sine wave from a HP 3324A to one sensor and looked at the output of
the other sensor with a Nicolet 440 scope. with 1 VPP amplitude I sweep
the frequencies from 1Khz to 50 Khz The highest amplitude was always at
6 Khz. Of the 14=20
sensors I tested they all responded the same. I concluded that the
sensors are not all that different and could be interchanged.I then
tested 9 external det modules from AASS,HKD,HKR,BLN,ANBZ ect. The
output is 10 volt until between 4 Khz and 12 Khz the output would go low
. Again 6 Khz was the sweet spot. =20

Subject: [Diy_efi] Question on Knock Sensors
Hi All,
=20
I went to the junk yard to gather parts and pulled several knock
sensors off of Chevy Suburbans with 350 CID engines.
=20
When I got back to the house with them and cleaned them up, none
have the GM numbers that are listed as being for 350s. In fact, all the
sensors have a number that starts with DR-699-#### where the # is a
number. In addition, all of them have different numbers for the last 4
numbers (####). =20
=20
Can anyone out there tell me what these numbers are for? Do you
have a cross reference to the GM part #'s.
=20
Thanks for the help.
=20
Dave
