What does a pressure reading on an AC system mean?
Well, the pressure readings of your AC system is what indicates whether the AC is functioning properly, or if there are underlying problems, such as leaking refrigerant, system damage, or worse, compressor failure, which can easily cost you a fortune in repairs.
What kind of refrigerant do I need for my Honda Accord?
Before starting, review the owner’s manual in order to verify the location of the AC system, and to confirm the manufacturer’s specifications for optimal pressure readings and refrigerant recommendations. R134a refrigerant with line sealant, hose and pressure gauge attached.
What should the pressure be on an AC compressor?
Note: The most ideal pressure readings are around 150 high and 30 low. Warning: Remember, venting 134a refrigerant into our atmosphere is illegal and bad for our environment. The following table presents the possible inferences and the actions that can be taken, based on the level of pressure registered by the high and low pressure gauges:
What should my AC low side pressure be?
When the engine is on and the AC is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. The correct reading will display once the clutch engages and the gauge stops cycling.

What does a low compressor pressure reading mean?
AC Compressor Pressure Readings & their Meaning Low Pressure Gauge High Pressure Gauge Inference/Action Required In range In range AC is working properly Low Low Add refrigerant Low High Need service, possibly blockage of the e High Low Need service, possibly faulty compressor
When the engine is on and the AC is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. The correct reading will display once the clutch engages and the gauge stops cycling.
How can I Check my AC low side pressure?
Just follow the user instructions of the pressure gauge to read your AC’s high side and low side pressure. The correct pressure readings depend on what car you have, and you can find the correct numbers out from your car manual. Here’s a simple guide that you can use to compare your readings with:
How is the pressure on a refill can measured?
To make sure you get as much refrigerant out of the can and into your system, you connect it to the lower pressure side of the system so it is the low side pressure that you see measured on the gauge on your refill can. To measure the pressure in the high-pressure side of your system, you need a little fancier piece of equipment.
What should the fuel pressure be on a CPI?
The CPI system’s fuel pressure should be between 60-66 PSI. The manual doesn’t specify if this pressure is key on engine off, only that this pressure should be maintained ‘ under all operating conditions’.
What should my AC pressure gauge reading be?
This is the second part of a series on AC pressure gauge readings. If you missed part I, start here. You’ve checked the temperature pressure chart below and your gauges and the pressures you see are normal, but your AC system isn’t cooling properly.
What causes a low pressure gauge on a car?
Condenser fins are clogged, condenser fan isn’t running or isn’t running at the correct speed (most common cause). Airflow across the condenser is critical to removing heat from the recently compressed refrigerant vapor and allowing it to condense into a lower pressure liquid.
How is base pressure calculated in gas contracts?
Using the basic principle of Boyles Law we can easily calculate a simple pressure factor (Fp) to be used for calculating changes in volume caused by increases or decreases in pressure. Base Pressure(Pb) is commonly stated in our Gas Contracts.
How do you get volume corrected for pressure?
So to obtain a volume corrected for pressure we must now multiply our Acf volume by 1.3177. In this case we would read the meter index difference and multiply it by 1.3177 to obtain the volume corrected for pressure.
When does the high exhaust system temperature ( Hest ) lamp DPF?
Once the DPF reaches approximately 840° F (450° C), the High Exhaust System Temperature (HEST) Lamp illuminates. When regeneration is complete, the engine returns to idle. If any of the above conditions change, manual regeneration deactivates and the engine returns to idle.
What should I do if my AC pressure is too high?
If either of these scenarios is the case, you need to either check for leaks and have any issues repaired before filling up the system with refrigerant to the correct specifications, or have a mechanic safely release pressure off of the AC system. When the engine is on
How long does the CRS purge air pump run?
If the DPF Lamp illuminates again, manual regeneration must be restarted. Engine Noise: If the truck shuts down during a regeneration, the CRS purge air pump will run for approximately 10 minutes. When key is on at truck startup, the air pump will run for approximately five minutes. This is normal operation of the pump.
