Different CSI Part numbers, also, should I clean? Options

[6gsillyca]

I just picked up a cold start injector sensor and coolant temp sensor off mr2oc. I havent had a chance to actually try them out yet, but Im hoping they will help with the cold start issues I was having last year. The sensors I recieved were from a 91 turbo mr2, but the csi sensor is different than the one I pulled from my car. I originally had the same one as art. The new one I got, is the one toyota says I "should" have. I was told (by 3 different dealerships) that the white one (20020) is intended for NA. If this IS the case, it puzzles me why jay didnt have any issues with cold start...

Original one = white ecu plug, P/N 20020, one side has 22, and another has 6M / 19 (one ontop of the other)
Replacement one = black ecu plug, P/N 20040, one side has 17, and the other has 5K / 18

Maybe this is why some people are having issues??


Back on topic, the replacement sensors I got are filthy. Should I clean them before I install them or just install them as they are. Im guessing that the coolant would clean them after they have been in there for a bit, but would it affect anything?

Replacement on left, original on right
