hello everyone i have talk before about this problem . coolant temp sensor failure
so i have put a video about this problem . the check from obd2 says is coolant temp and intake air temp sensor . so with service garage we have change the 2 sensors <intake air temp and coolant temp > the problem still on . check the wiring everything is normal with 5volts we have check if there is any cut . there is nothing . the ecu working perfect . the plugs from the ecu to the sensors getting 5volts everything good . so whay i still get this error because the car not working when this error is on .obd2 still showing the same errors even with clearing the faults is coming back immediately . so any help any ideas I really appreciate it .
this is the video

Can you monitor the actual temperature being given with MES? A spike up or down may indicate an intermittent fault with a plug, wire or dry joint on ECU

Did the garage clear the fault codes? If not, I believe it takes several 'good' starts before the messages disappear...

thanks for feedback guys . we have check the ecu is work normally there is no problem with ecu . i have take the ecu to the company they repairing ecus and softwears things. so yeah everything is okey the wiring getting 5 volts there is no cut. and even with clearing faults this error is not gone . still on . even is not disappeared and then comin back . no is not going at all just when click on clear botton is the error on dash is flashing and still on . so really i dont know what to do . i'm thinking to change the thermostat this the last solution.

Could the coolant temp sensor failure be a red herring? I was getting all sorts of warnings when my battery went low. If it was on a good charge I got the abs warning all the time. I bought a new battery and all problems have gone. Nice quiet car on start up with no warnings.
