The EMS light stays on my fiat punto grande 07 and the engine is difficult to start when cold and the fan motor starts when the engine is switched on and the temp gague doesn't work at first. Eventually coming on but only when the engine has warmed up and the engine is switched off and then on a few times. Any idea what is wrong with my car?

Changed the MAP sensor and the coolant temperature sensor but the check engine light is still on? What else could it be? Or how do I reset the engine error light?

Also where is the IAC Idle Air Control? Thanks.

Check the fuse box in the engine compartment is dry inside


And for the love of god make sure you put the lid back on correctly after looking

Changed the coolant temperature sensor but still getting the excess radiant temperature turn off engine error and also the engine light is still on. Any ideas?
