Hello,
I'm trying to replace a CTS which communicates with the ECU to control fuel enrichment and which commonly goes bad. This rubber molded connector is integral to the sensor assembly. The pins are close to 2mm bullet connectors. However the 2mm bullet female was too small for the original male and the male 2mm fits the original female but it is a little loose.

I was wondering if AAW has any experience with the connector assembly or even the correct bullet connector size. If not did GM perhaps associate these with a name like they did with other connectors which would make search easier?

I'm adding some pictures and sketches. I don't want to destroy my original failed sensor to get better pin measurements so especially for the male I may have underestimated the diameter but only slightly.

These photos are from a 1979 Cadillac Eldorado but the same sensor was used on all GM (at least Cadillac) from around 1970 through 1979.

Thank you,
Scott

Sorry Scott, but we do not have anything like this. Not even sure what it is or what family it might be.

Ok Thanks for looking. I think possibly if I could find a split barrel bullet it may work better than the type I found but I haven't found any split barrel bullet connectors which are positively identified with a size.

Split barrel meaning that the male is formed from flat stock into a round shape. Not certain of the official name but one like this capture.

Scott, these are not what you are seeing in those other connectors. Just an FYI.
