P2613 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2613 can be described as A/C Refrigerant Distribution Valve Control Circuit High. This means that the PCM is detecting a high voltage output from the distribution valve circuit leading to error code getting stored in the system.

Any fault in the A/C refrigerant distribution valve control circuit can cause failure in the heating and cooling system of the vehicle. This will cause uncontrolled cabin temperatures and/or the air conditioning system to entirely shut down. Since the PCM is unable to complete one drive cycle, it may also cause the internal emission monitors to shut down leading to failed emission tests.

What causes this problem with the A/C Refrigerant Distribution Valve Control Circuit High?

• There might be less refrigerant in the air conditioning system
• Sometimes there might be too much refrigerant
• A lot of system pressure
• There can be distorted A/C refrigerant pressure switch
• Imperfect electrical connectors
• Shorted, open, or distorted wiring
• Defective control head

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
3. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues?
4. Diagnostic Tools – Use factory grade diagnostic tools to resolve OBD code P2613 error. Buy new diagnostic tools and equipment for us.
5. A/C Compressor - Sometimes loud noises might start coming when there is a failure in the AC compressor. So it is very important to replace the A/C compressor with us at equitable prices.
6. A/C Connectors – Defective connectors will cause the cooling and heating system to behave erratically and must be replaced immediately. Buy new connectors from us.
7. Ambient Air Temperature Sensor – Another symptom of a bad or failing sensor is an incorrect reading on the vehicle’s temperature gauge. Most vehicles will have some sort of display somewhere on the interior of the vehicle that indicates the outside temperature of the vehicle, usually read by the ambient temperature sensor. If the reading on the gauge or indicator is off by more than a few degrees, then the sensor should be replaced, as the incorrect reading may interfere with proper AC system functions.

Common Symptoms

• Check engine light can start flashing up
• The on light for AC might start appearing
• Failed emission test
• Ambient temperature control system not working

We have listed out so ways which would help you to correct the occurrence of OBD Code P2613. They are mentioned here as follows:

• The malfunctioning refrigerant should be repaired or replaced as per the need
• Carefully adjust the faults in the A/C refrigerant distribution valve
• The electrical connectors should be restored to working order
• Recondition the non-functioning wiring and connectors
• It is necessary to perform proper service of the unsound control head
• Adjust the flawed A/C refrigerant pressure switch

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of ECM, A/C Refrigerant, Electrical Connection, Temperature Sensor, Valve Rocker Arms, PCM, A/C Compressor, Connectors, Cruise Control Module and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the A/C Refrigerant Distribution Valve Control Circuit itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and A/C Refrigerant Distribution Valve Control.
• If the A/C Refrigerant Distribution Control or other related parts are not faulty, he will then retune the code and test drive the vehicle.
• Now when the car is taken out for a test drive, if the P2613 code does not return soon, he will know that there is an existence of erratic condition.
• Always check for the refrigerant levels and maintain optimal levels to reduce the added pressure on the system.
• Check for PCM faults that may require replacement and reprogramming.

Common Mistakes When Diagnosing the P2613 Code

There are a lot of mechanics who assume that there might not be enough refrigerant in the system after seeing this code, so that immediately add more. This can turn out to be a big mistake though. Now if they will add excessive refrigerant when it wasn’t actually required, then it might cause the system to fail catastrophically. It is very essential that the technicians make a thorough investigation to find the true cause of the issue.
