Thanks to the forums I have run the onboard diagnostics for my A/C that is not blowing cold.

My ECT sensor #6 is reading E. I cannot find a part # for this sensor and have not been able to find out if it could be causing my compressor to not turn on.
Sensor # 7 reads 6 bar.

Can some one please help with the ECT mystery??

Other codes are 1234 sun sensor
and 1227 outside temp sensor
I don't think either are critical for this problem since so many others report
these same codes with working A/C.

My EC light was on, and would not turn off until clearing codes and adding 16 points to the right side temp 136 to 152. After a couple of restarts the EC light is now off however as before compressor will not kick on to take more R134. Car is super low mileage at 33k

Thanks and Aloha

Many owners have reported code 1231 (ECT sensor) when running diagnostics for A/C not blowing cold. No one mentions replacing this sensor as solving their problem, its location, or part #. Online OEM part sellers have no code fault knowledge and ECT sensor is not something that means anything to them.

Can someone provide some useful information here please?

Thank you for taking the time to read about your car before asking all sorts of questions---however with the AC system please post the actual values and then go back and run and post the fault test.

With that information you will get help---without the information--you will be better off by taking the wife out for a pizza!!
