Hi, im new to this forum.

Ive had this problem for a while now and i was hoping u guys could give me some advice.

When the engine lamp turns on, the rpm will rise to 1500 from its original 800rpm. And when i turn the engine off, i cant start it. I will have to wait for approx 5-10 minutes and try again.
I get ECU code 06,

ECT Sensor (Engine Coolant Temperature)
defective circuit or unplugged / defective sensor


thx.
