My Cady Catera 1998 has RPM about 450-500 all the time and no any lights like check engine or somthing,no problems with running and starting at all,just low RPM when you don’t drive. I ran diagnostics at the shop and they found out that crankshaft position sensor needs to be replaced and they wanted 400$ for that. So yesterday I replaced crankshaft position censor like I red on this forum. It was not so hard I spent more time to get a good one from another Cady ( i got used one) then to put it on mine. So as a result- NOTHING!!! A same thing!!! 450-500 RPM with another crankshaft! How I understand if crankshaft died it means no start engine ( like usually) and in my case I might have no good crankshaft sensor but I can't bealive that another one is a same! Cuz I’m preatty shure that another one was good cuz I know that car was running greate. So my question is what’s a main reason of it? I dano what I need to do now…Any ideas???
