You can bypass the AC low pressure switch, on your Toyota Corolla, by removing the switch. You can remove the wiring to the switch and leave the switch and place.
A pressure switch a valve that shuts off the unit when the pressure is to low or to high
On my service DVD i cant seem to find a low pressure switch. i did find a AC refrigerant pressure switch i dont knwo if its the same
Of which low pressure switch are you speaking? Engine oil pressure switch? If you're checking that, remove the oil pressure sending unit and temporarily put in an oil pressure gauge. If you're checking the AC low pressure switch, pull the switch from the AC low pressure line, Jumper the switch socket and see if the AC compressor comes on. If it does, you either have low refrigerant pressure or a bad switch. If you KNOW the pressure is up and everything else works, you have a bad switch.
The ac pressure cycling switch is designed to engage or dissengage the clutch to keep the proper pressure in the system.
The AC low pressure switch of a Honda Civic is located on the driver's side of the radiator. It is screwed into the accumulator bottle.
TThe low pressure AC switch is a 3-way pressure switch in the low-side refrigerant line. It is open when the pressure is approximately below 27 psi and above 350 psi and closed when the pressures are in between.
The low pressure switch is usually on either the h valve, accumulator, or in the suction line.
on a 2005 Honda Accord where is the low pressure AC switch
There is actually a low-pressure switch and a high-pressure switch. The low-pressure switch is located on the right side rear of the engine compartment on top of the AC accumulator. The high switch is on the AC high pressure line in the area behind the left headlamp assembly. Niether one is hard to replace, it's self-explanatory when you see them.
follow the refridgerant lines from the compressor.
it does not have a high pressure switch all it has is a evaporator temp sensor/switch.
