What should the pressure gauge be on a Honda Civic?
The gauge should show close to 80 pounds on the blue low side and 140 on the red high side, depending on outside temperature. This is with the compressor off. It takes this much pressure to turn the low side switch on and allow the compressor to work.
How can I tell if my Honda Civic has an air conditioner problem?
There are two connectors under the hood attached to your A/C’s refrigerant system that should be labeled as such, one for the high Psi end of your gauge (the red side) and one for the low end (the blue side). If the level is unbalanced, it will cause the entire air-conditioning system to shut down as a protective measure.
What happens when you stop the Honda Civic a / C compressor?
Discharge pressure abnormally high After stopping A/C compressor, pres- sure drops about 196 kPa (2.0 kgf/cm2, 28 psi) quickly, and then falls gradually. Air in system Recover, evacuate, and recharge with specifi ed amount. No bubbles in sight glass when A/C condenser is cooled by water.
How does an expansion valve work on a Honda Civic?
Expansion valve: This takes high pressure Freon and turns it into a low pressure, low temperature spray that moves into the evaporator inside the cabin and withdraws the heat.
What’s the air pressure in a Honda Civic?
Ambient temp Humidity % Inlet air temp Static system pressure 45 psi minimum Center vent temp ~30°F < ambient Low side pressure Typical: ~ 30 psi High side pres- sure Typical: 2.2 to 2.5 X ambient °F Pressure behavior when AC is shut off: High Side Pressure PSI Low Side Pressure PSI Center Vent Air Temperature °F Inlet Air Temperature °F 1.

Where is the pressure switch on an air conditioner?
The AC pressure switch іѕ a ѕаfеtу ѕwіtсh thаt monitors the рrеѕѕurе оf thе refrigerant on the high and low-pressure sides on your air conditioning system. So, you do often have two different AC refrigerant pressure switches on your car; one on the low-pressure side before the AC compressor and one on the high-pressure side after the AC Compressor.
What do you need to know about Honda Civic a / C?
2006-2011 Honda Civic A/C Diagnosis and Repair EXPANSION VALVE (Meters the required amount of refrigerant into the evaporator) RECEIVER/DRYER DESICCANT (Traps debris, and removes moisture) A/C COMPRESSOR (Suction and compression) A/C CONDENSER (Radiation of heat) A/C PRESSURE SENSOR
Why is the AC not working on my Honda Civic?
I mean it’s always worked, but I always found the AC in this car really weak compared to my 2013 Civic which blows ice cold air the moment the AC is set to Low Click to expand… Either your A/C coolant is low or you may have the compressor leak as well.
Why does my Honda Civic have low compression?
Typically if only one cylinder is low on compression, the motor will just run poorly. The causes for low cylinder compression are typically a bad head gasket, worn piston rings, or bent valves. Low compression from those problems are also accompanied by other problems, like coolant in the oil, an engine that burns oil, or noisy operation.
