Really helpful - have been driving around all summer with the warning light intermittently going off even though the coolant level was fine. I took out the sensor expecting to have to do a soldering job like you, but found one of the two probes was covered in timescale. I cleaned that off and refitted it and all is fine.
Give it some time - I did this first too, issue came back some time later. The process of cleaning the probes may have improved the bad solder joint for a while.
Coolant level sensor ... turbo diverter valve... door check straps ... the exact same things wrong with my 308. Thanks for showing how to fix all my car problems! (Well nearly all, shudder on braking is the last, might take it to a mechanic for that.). And thanks for the glass roof tip too.
Thanks for the video. Very useful information. I have a Peugeot 308 1.6T, which the error message is a little different, it shows" Coolant level circuit too low. But I checked the reservoir, it still closes to the maximum level. Not sure if I replace the sensor, the error message can be resolved or not. Thank you very much
I've never measured myself, but this sounds maybe right. Pin 2 needs to be pulled high by the ECU to 5 or 12V. If the ECU is polling this signal (very likely) then your multimeter will be seeing the average voltage at this pin which could explain why you measure 3.3V. If I get a chance I'll make a measurement out of interest.
@@sinasarhadi90 In water = open circuit: (you wont measure anything), Out of water = connection to ground. Measure continuity between ground and pin 2 to test.

Are these the right voltages on the connector side?
1 ground
2 3.3V
3 12V

@@Justfixitmate hello my friend. can you measure pin 2 voltage when the sensor in water and out of water?
