nissan sentra se-r like 91-93 had an sr20de motor, the CTS is the same. since you broke it buy a new one. go to autozone, napa, advance, pepboys, etc and just replace it, won't cost more than $20 :)

just do a little more research before cuz 91-93 might not be 100%, but it will show up as DOHC 2.0 on their system prob.

yes...that is the case. if you broke your ECT sensor, your PCM will think you're engine is stuck at -40° and will keep your injector on-time longer.

For an S13 SR yeah thats correct

Part number is 22630-51E00 if you visit the nissan dealer.

I got mine from courtesy and I tried to put it in today on a ka24e. just to let you all know that you need a 19mm box wrench because a socket won't fit with the line there. I was like why nissan why LoL. Well I got a wrench and I'm going to replace it tomorrow. The line is metal, why couldn't they have used rubber LoL.
