Since the only FSM available online is for the 94, it has no info in regards to the R-12 AC system and I need some info. So if anyone has the 89-91 (and possibly 92) FSM:

1. Does the AC temporarily turns off when the ECM detecs high engine load from the TPS during acceleration?

2. Can someone provide the values of the ambient temp sensor (the one by the horns) that is given on the electrical components section?

 

im looking at my book form 92 service manual(has both vg and ve sections)

1 . briefly mentioned on pg HA-160 as follows,
ACCELERATION CUT CONTROL = "the eccs will turn the compressor ON or OFF based on the signal from the throttle sensor"

ALSO ON PG HA-14 as follows "ACCELERATION CUT SYSTEM -FOR MANUAL AIR CONDITIONER
system is controlled by the E.C.C.S control unit when the engine is heavily overloaded ,the compressor is turned off for several seconds to reduce overload

2 . pg HA-148 disconect harness by hood lock stay and ohm check the 2 prongs on the side that goes into the sensor
THIS IS THE PART THATS TOO MUCH TO POST the full chart..

depending on what temp it is outside and i guess the actual temp of the sensor body so......
AMBIENT TEMP
50*F=3.99k , 59*F= 3.24k , 68*F = 2.65k ,
77*F= 2.19k , 86*F= 1.81k , 95*F= 1.51k ,
104*F,= stay the f home or = 1.27k .......good luck U

 

Thanks a lot!

Gives me time to think if I should stick with the ambient sensor or replace it with that thermal control amp hanging by the evaporator.
