D15b7 check engine light... Coolant temperator sensor

- Sun Aug 18, 2013 6:06 am #335579 When it thrown the cel codes, states coolant temperature sensor. I got the sensors for free from my friend and replaced the coolant temperator sensor. Reset my ecu. It stills have check engine lights on.

I thought; part might be fault, bad wire, or? :?

Thanks

I am not sure if it is used or new so I will say it is used sensors since I got it from my friend.
Pretty much, it worked as I turned engine on as temp gauge was at cold and I drove it around for a bit then arrow gotten up to middle between cold and hot.

Forgot to mention this
Whenever I park my car and let it cool completely (5 or more hr). I turned engine on and it seemed so tough to stays on idle and shutted off. I give another tries and it runs fine when I give it the little gas to keep idle and warm.

it can have problems starting hot/warm. happend to me

pretty much the coolant tempature sensor reads as the engine being cold so it pumps all the fuel it would if the engine was running high as it does when its cold. causes starting problems and running problems and poop it sucks cause it can go bad but not throw the code.

there are 2 coolant tempature sensors. one is the sending unit for the cluster and the other is for the ECU

From what you mentioned about runs super rich when my temp sensor goes bad. I am not sure what my car will do but maybe because it idles at 1100-1200 after start up. Is that what you mean?

- Sun Sep 01, 2013 10:19 pm #336220 Okay I just bought one sensor since local auto part only have it available

So I replaced it under distributor then reset ecu by pulled my fuse out for 15 minutes
Nothing work, still has CEL light on after running
Last thing I could think of is to disconnect battery and am waiting for 15 minutes right now.
