Hi
My truck has been running well for a while now ,no ses lights then all the sudden,after morning startup(aboue65deg) that ses light came on and stays on untill about 20/50 klm.
At start,the engine stays at very (low idle 300??)up if i unplug the new coolant sensor (which has proper ohm readings)the engne will jump to about 900 rpm and light goes out.I have replaced the crank position sensor,coolant sensor ,and fuel filter numerous other parts and the engine was working grat.I dont have a tech 1 yet ,but am working on a laptop with ease/obd diagnostic.
Do you have any idea what could be causing this symptom?
Thanks for a great site.
