Hi all. I have a 4-door Honda Civic 2006 LX 1.8.

The engine light came on last week. The mechanic's computer gave error codes P2183 and P0111. I replaced the Engine Coolant Temperature sensor on top with a genuine Honda part. The engine light went away. Then today it came back on, then went off by itself, then it came back on and stayed on.

Today he got the following codes: P2185, P2183, P0111, and P0128. I did my research and these codes seem to be common for this car, but I havent found any conclusive solutions or answers as to what fixed the problem.

I found this useful: http://ww2.justanswer.com/uploads/Ho...201805_hyb.pdf. And the common opinion on the internet says it is a corroded or broken pin from the ECT #2 sensor at the bottom of the radiator, but I havent found any reports that confirmed the error codes going away after replacing the 2-pin head on the ECT #2.

Before I go ahead and replace the ECT #2 or the 2-pin head, does anyone know if this is most likely the ECT #2 sensor, the thermostat, or the IAT sensor?

I'm trying to repair this myself so any tips you can share would be muchly appreciated it. Thanks

 

Maybe try inspecting the connector to see if the pins are actually corroded instead of outright replacing the part?

 

do you think I may be able to clean the corrosion off of the pins or the sensor itself? How would you recommend I do that?

 

Are you saying you have corrosion or you're just anticipating it?

 

Replaced the ECT2 sensor and reset the engine light. It's been off for over a week and 700km. So I think that might have solved the problem. Even though when I took out the old ECT2 sensor it was still shiny and looked new without any signs of corrosion on it. Didnt notice much corrosion around the 2-pin terminal/connector or the wires either.

 

Hey guys, Im new to this forum and I have a question about this particular error code. I tested the ECT and its working fine. So I went ahead and replaced the thermostat, as it was recommended on the internet. However, the check engine light is still on. I did it a day ago, and Im not sure if it takes time to clear. Since Im doing this myself I would like some input on what other things I should try. Thanks all!

 

Usually after you reset the code it take about an hour or a little more for the code to come back... you should good now!
