Let me rephrase my question. What error code would I get if my AC compressor went out?

 

jus filled up on freon. its icy as hell now.. thank god!

 

DAMMIT!!! code 43 jus popped up and its not cold anymore

 

any know wat the air outlet door servomotor circuit is? how much does it cost to get fixed?

 

do some of these codes prevent a/c from getting cold ? I
get a code 12 ambient temp sensor.

 

the ambient temp sensor means.. well i mean if you have that.. your car either be Cold or Hot. nothing inbetween.

 

i don't understand your reply

 

What vwynn is saying is that if your ambient temp sensor fails, the air coming out will be either max cool or max hot but no in between. However, the manual disagrees (not saying I do) because checking this circuit is not part of diagnosing "No temperature control, only max cool or max hot". In any case, yes your temp circuit failure is a possible cause to your air temp problem-according to the diagnostic chart.

 

thanks for clearing that up. the A/C has not been cold since I put the car back together and after charging that was the code I got. I call lexus and they want $140 for that lil thing. whats odd is I checked the resistance like the manual says and it seemed to have been to spec. and I check continuity from the back of the a/c ecu to the sensor plug.

 

I guess i should had asked, does the ambient sensor code cause the compressor not to lock/turn on ?

 

just checking if you got this code fixed?, and how much it was?...i am also getting code 41.... anyone?...
Thanks

 

No, there is nothing in the manual that suggests this would happen. Is your compressor not turning on? You should be able to hear it kick on.
If you are in "auto" ac mode, try switching to manual and set your temp all the way to max cool. This takes the ambient temp sensor completely out of the equation. If you are still blowing warm air, you have bigger issues.

 

Thank ! well I found out I had a plug not plugged in from the 1jz harness. that code went away. I still get 43 but its because I dont have the vac line connected to it.

BUT the compressor stays locked on even if I turn a/c off (which is not cold)
it unlocks when I unplug the plug on the compressor

 

no i didnt. i have no clue wat it is.

 

hey im also getting 43. lemme know if you fix it n how you did it
