Error 11 Solar Sensor Failure

[Alan Tann]

After put my MK2 Lexus into diagnostic mode, I am getting error 11 and 23. I know that 23 is low gas and I'm going to get it regased in April.

I want to check with the solar sensor not working, does this only affect the auto mode or will the air con not work at all with this error?

Many thanks Alan.

My book shows code 11 as room temperature circuit and solar sensor circuit as code 21.

I can't see a code 23

If there is not enough refrigerant the compressor will not run.

Does your run?.......may not run if it's freezing outside!

No it does not run as it refrigerant is to low and needs regasing.
