The refrigerant pressure sensor, or switch, is designed to protect the A/C system against incorrect refrigerant pressure.

The replacing of any air conditioning component requires recovery, internal drying, leak testing, and recharging the system.

P2613 code definition This is the generic trouble code for A/C Refrigerant Distribution Valve Control Circuit High, indicating a problem with the signal being sent to the PCM from the distribution valve circuit.

P2517 code definition The P2517 code indicates that the A/C refrigerant press sensor B circuit has low voltage.

The receiver/drier is designed to store and dry A/C refrigerant.

P0533 code definition The P0533 code shows when the signal circuit in the vehicle is detected to be too high.

There is never a good time for your air conditioning in your car to stop working, but it typically seems to happen in the dead heat of summer.

When the air in your air conditioning (AC) begins to lose power and the air doesn’t feel too cold, it may be time for an AC recharge.

All across North America, a climate change occurs every year.

All air conditioners use a refrigerant, whether it's your car’s HVAC system, a central heating and air system, or your home’s refrigerator.

R1234yf, the refrigerant jointly developed by Honeywell and Dupont that is being phased in as a replacement for R134a in Europe, is safe. So says a panel of scientists from the Joint Research Council, researching the refrigerant at the request of the European Commission. German automaker Daimler, though, disagrees with the finding, saying R1234yf can be toxic to humans when burned, according to Automotive News.

We don't have any new supercars to show you today. No new Teslas or SUVs. No new engines or technologies. No mergers, acquisitions or big hires. What we have to tell you about is the coolant automakers are putting into their vehicles. Which may not sound so exciting, but it could mean a big difference for automakers – and for the environment.

Report

France's highest administrative court said yesterday that authorities must resume registering Daimler vehicles, which were formally banned in late July, Automotive News reports, even though they are still equipped with R134a air-conditioning refrigerant.

On this episode of As the A/C Refrigerant Turns, the KBA, Germany's motor authority, has released its findings on the refrigerant r1234yf. The joint venture of Honeywell and Dupont, r1234yf has pitted Daimler against France and Germany against the EU; Daimler refused to use the new refrigerant, saying it's more dangerous to occupants in a crash, so France refused to register Mercedes-Benz cars that used to old, non-EU-approved refrigerant. The latest step was France taking steps to formally ban

That didn't take long. Shortly after a French administrative court gave the French government a ten-day window to reconsider its ban on registrations of Mercedes-Benz A-, B- and CLA-Class cars using the prohibited R134a refrigerant, the government cited an EU directive to formalize banning the sale of the cars. The country's environmental ministry said that registrations "will remain forbidden in France as long as the company does not to conform to European regulations," meaning so long as they

The brief alphanumerics R134a and R1234yf are codes for a growing battle between carmakers, states and the EU. The air-conditioning refrigerant R134a has been banned by the EU for being too damaging to the environment, with R1234yf mandated as its replacement. Daimler and Volkswagen say that in their own studies, though, R1234yf can be more dangerous in an accident, potentially starting fires and releasing poisonous hydrogen fluoride gas.

Report

The last time we checked in on the battle of refrigerants, France had enacted a registration ban on some Mercedes-Benz vehicles because their air-conditioning systems were loaded with R134a, which was found to be harmful to the environment by EU tests. Now, other EU states are considering banning the substance, according to Automotive News, as they push for a new refrigerant, R1234yf, to be used in new vehicles across the board.

Report

General Motors' Opel division is adding metaphorical fire to the real dispute over a new air-conditioning refrigerant's potential flammability.

Official

Another German automaker has rejected the air conditioning refrigerant that's scheduled to be adopted by global automakers in 2017. Earlier this month, Volkswagen lined up with Daimler and BMW to support Daimler's findings from last year that the new refrigerant, called HFO-1234yf, can become flammable.

Report

BMW has joined Daimler and, potentially, Audi in quitting an automotive industry research program studying a proposed new air conditioning refrigerant, the simply named HFO-1234yf. BMW disagrees with the test methods being used. "We do not want to say the test results are wrong, but we are not convinced the methods applied are sufficient to achieve a definitive conclusion that guarantees our high safety standards," a spokesman for BMW told Reuters.
