OBD error code P2586 is a generic error code that indicates some problem with your vehicle’s turbocharger boost control position sensor “B” circuit. Now, you must be wondering what is this problem and how does that matter when it comes to your vehicle’s performance? Another question that might be haunting you must be how serious is this problem? Well, to get your answers to all these questions you will need to go through the subsequent sections.

To be able to solve any problem you need to understand that problem completely. Keeping this in mind let's try to understand what exactly this OBD error code P2586 indicates. OBD error code P2586 will be set by your vehicle’s powertrain control module when it senses some failure with the TBCPS system. In other words, it will set this error code when it detects some issue turbocharger boost control position sensor “B” circuit.

What causes this problem with the Turbocharger Boost Control Position Sensor "B" Circuit?

• Turbocharger boost control position sensor open circuit
• Signal circuit to the TBCPS sensor having short to voltage
• Possible TBCPS sensor failure
• Powertrain control module failure

1. Powertrain Control Module - Also abbreviated as PCM is an integral control unit. So, a defective one should be changed immediately replaced to avoid any further damage. If you need one for your car, you can easily find with us for your specific car make and model.
2. Turbocharger Speed Sensor - Your vehicle’s turbo speed sensor is responsible for detecting the rotational speed of exhaust-gas turbochargers; hence you can’t afford to go with a faulty one. Replace the bad ones today and get rid of that annoying OBD error code P2586.
3. Turbo Pipes - If your vehicle is set to OBD error code P2586, chances are that you are facing turbo system failure. If you wish to fix it and need parts to do so. We at PartsAvatar can prove to be your dream destination.
4. Spark Plug - Believe us or not but replacing the faulty spark plugs is a way of assuring top efficiency and performance for your beloved vehicles. So, what are you thinking? Replace the bad ones today.

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

Begin your diagnosis you will need few tools and equipment such as an OBD-II scanner, boost pressure gauge, hand-held vacuum pump, vacuum gauge and also a dial indicator set. To begin with the diagnosis, you will first need to test drive your vehicle and check for any engine knocks or engine misfires. Also check carefully the turbo hose amps, turbo intakes and intercooler connections against any leaks or cracks. Look for any sort of tightness or malfunctioning in the air intake hoses. In case you discover that all the hoses, plumbing and connectors are good then take the turbo and make an attempt to move it into the intake flange. In case the housing is found to be movable then try tightening all the bolts and nuts as per the manufacturer’s specifications. Also, do place a boost gauge to make sure you can see it while actuating the throttle.

• Next step is to test drive your vehicle in a park and rev up the engine to 5000 rpm while releasing the throttle quickly. Carefully look at the boost gauge to see if it exceeds 19 pounds. In case it is below 14 pounds, there might be a turbo or exhaust problem. In this case you will need to undergo a visual inspection of all the related wiring and connections and replace the damaged ones before retesting the system.
• If you find that all the wirings and connectors are good, then attach the code reader or scanner to the diagnostic port. Record and freeze the data and clear the codes before test driving the vehicle. In case the code fails to return, then you might have an intermittent condition.
• Now, disconnect the actuator arm from the wastegate assembly and make use of the vacuum pump to manually engage the actuator valve. Carefully observe the wastegate to see if it can open or close fully. In case it can’t close or open completely then it will lead to a drop-in boost pressure.
• To inspect the turbocharger malfunction you will need to remove the turbo outlet hose and look inside the unit when the engine is cool.
• Check the unit for impeller fins that have been damaged or are missing, and look for signs that the impeller blades have been rubbing the inside of the housing. Also, check for the oil inside the housing.
• Now, you will need to use your hand to spin the blades and look for loose or noisy bearings. All these conditions will indicate towards a failed turbocharger.
• Next step is to install the dial indicator on the turbine outlet shaft and check lash and endplay. The excessive endplay will be observed if anything is outside of .003.
• In case you do not find any problem with the turbo and wastegate then locate a constant supply of vacuum at the intake manifold and connect vacuum gauge. Remember that a good working engine would read between 16 and 22 inches of vacuum, anything less than 16 inches will indicate towards a poor catalytic converter.
• In case of no other obvious problems, re-test the circuits, wiring and connectors of the turbocharger boost sensor.
• Lastly, check the voltage and resistance values against manufacturer’s specs.

Common Mistakes When Diagnosing the P2586 Code

• Failing powertrain control module (PCM)
• Failing turbocharger speed sensor
• Problematic circuit wiring
