light on my dash lit up... help

I sit at about 500rpm

 

You said that you had just flushed the coolant? Perhaps it still has air pockets in the system? This can cause the sensor to show hot when the coolant temp is actually normal. Did it stop sucking coolant from the overflow reservoir and you topped it off?

Could be something else but being as it hadn't done that before the flush, but does afterwards, it is something to consider. Good luck OP!

 

I did the flush about 2 month back and everything has been fine until today

 

Probably not an air pocket then. Could be a faulty temp sensor . . .

 

Idle should be between 5 and 600. I'm assuming an air pocket. A pocket of hot air in the cooling system sitting on or next to the ECT sensor will cause the Coolant light to illuminate. If you didn't burp the system while filling with coolant, there still could be an air pocket hiding in there

 

Any idea of what the actual fluid temps are when this is happening?

If you have access to an OBDII scanner like a scangauge or an ultragauge, they will tell you whether or not there is a problem. I have found the stock dash temp gauge to be a very poor indicator of small changes in fluid temps.

 

Unplugging the battery will clear an OBDII code, but it will clear a sensor-driven light such as washer fluid, low fuel, temperature, etc.

 

Thinking it might be my coolant temp sensor... or the wiring going to it shorted..

Question is in order to change the part it seems to be under the intake manifold is there an easier way to get to it or take it out without removing the manifold?

 

It everything else electrical is working and the engine is starting normally, check the terminal connection on the coolant temperature sensor. It might just be loose. Otherwise, before you spend a lot of money or time troubleshooting your wiring, clean and tighten your terminal connections, especially the ground connection between the frame and the engine block and battery posts. If that does not fix the problem, replace the sensor.

 

Is this the ground to the sensor

This is not the ground to the coolant sensor stupid Haynes Manuel..

 

I have this light come on when i turn my headlights/parking lights on, its the same color as the rest of my dash lights an only comes on when i turn my lights on and goes out when i turn them off not sure why anyone else have this problem

 

Same problem I'm still having. Trying to find a buddy with a scanner but so far no luck.. I'm going to unplug my coolant temp sensor and see if it goes away.. have a feeling its a electrical short. Still have no clue what the fuse is that the system runs off of..

 

Wait a minute. You guys are saying that light comes on only when the parking lights and lights are on? Do you guys have an actual temp gauge like in this pic all the way to the left? If so that light just shows that that gauge reads the temp

 

Well that answers my question haha thanks

 

Glad I could help

 

LOL!!!!!!!!!!!!!!!!!!!

And here I thought it was mixed in with the idiot lights on the cluster.

 

Burp/bleed the radiator. You may have air in the system causing the light to come on.

 

Haha so did I until they said it only comes on with the parking lights and head lights than I knew exactly what it was.

 

Strange because mine was out before maybe the bulb is starting to go. Its only come on in the past week maybe it was a loose connection? Hmm well its on now..lol I feel very stupid

 

Flame away guys I'm getting a laugh out of it too
