Im getting this code, WHere is this??

[artisticent]

15 - Coolant temperature sensor or circuit/ low temperature indicated - Coolant temperature sensor signal indicates a temperature colder than -36? F for at least 4 seconds after the engine had been running for 2 seconds.

I replaced the waterpump, all hoses and a 160 thermo. It was good for about a week until I was messing around changing the turbo oil return line. Now the code trips almost right away. I am replacing vacuum lines but the idle is pretty bad and I dont like having the check engine light. Could I have pulled out this plug? could it be the 160 thermo??
Thanks

check the 2 rings on the bolt for the thermostat, make sure they're not cracked or detached or anything. Mine pulled that code when 1 came off.

I will check that. I know for sure I reconnected 2 ring end wires but one may have become faulty. Like I said it was fine for a week.
thanks

If I remember right there's two coolent sensors.. one in the lower intake manifold and one in the driver side head by the exhaust manifold. I'd check these out or at least reseat them then plug the ecm b fuse for 15 minutes to reset the ecm then start her up and see if the code re appears

Th drivers side goes straight to the gauge cluster whereas the lower intake one goes to the ECU.

The one on the driver's side has a green wire off it. The ECM one has a double connector not far from the coolant hose going to the radiator.

HTH.;

Ok, well it turns out that the coolant sensor next to the thermostat was broken in half. It looked ok coz the plug was attached but the thing is no good. Ill buy a new one today. I still have an issue that when im idleing, the very first bit of acceleration I give it, it feels like it wants to die, and then right after it goes no prob??

If no temp sensor, the open circuit might be giving the engine a cold start signal making it rich on start. Once above a certain rpm setting for a few minutes it might be ok. That is just a guess - I think it tells you in the cd or the manual if that is the case.

Right, I just was reading your old thread on the same thing. But my gauge is ok. Did you need what I need or the thing that tell your gauge whats going on? Also is is s-10 stuff or sy
Thanks

I replaced both. What do you mean "is is S-10 stuff or sy?"

Seems like we are getting somewhere?!!

Sorry, i meant syclone specific or any 91 s-10 part. Its sorted now anyway, I went down to the auto shop and bought the right sensor and Roberts your fathers brother. I did notice though that can the belt be on too tight?? I noticed the idle is not great and today I noticed that in drive when I turn the wheels in place it drops to about 500rpm. It seems like the belt is putting a strain on the motor by bein too tight? Possible?
