OBD error code P2587 flashing? Tensed on how bad it can affect your vehicle’s health? Well, you might not like to hear it but it can be extremely fatal for your vehicle’s overall health, if not addressed soon. If you face this error code then you must get it diagnosed and do not relax until it is fixed. To know more about this problem, read through our following sections.

As many of us already know that the powertrain control module manages the boost from the turbocharger using a turbocharger vane position solenoid. OBD error code P2587 will be set by your car’s pcm when it detects any electrical problem with the turbocharger boost control position sensor “B” circuit. To know more about this error code, take a look at the sections below.

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

• Turbocharger boost control position sensor circuit “B” developing an opening
• TBCPS sensor having a short to the voltage
• TBCPS sensor having short to the ground
• Faulty TBCPS sensor
• Faulty powertrain control module

1. Powertrain Control Module - A faulty Power Control Module (PCM) can become irregular to an extent that your car will fail to start or will begin to stall while running. You will notice that exhaust fumes are shorted while the car is running and emissions system control indicators are decreasing. So having a PCM that isn’t working properly is not a good idea, you need to have it replaced right away to resolve the obd error code P2587.
2. Turbocharger Speed Sensor - The turbo system of your vehicle is responsible for providing a key input parameter for the efficient management of the turbocharging system. So, never take a chance and replace the faulty ones at the earliest. You can buy the best ones with us at PartsAvatar.
3. Turbo Pipes - If you need one, you can simply find it with us. You can choose from a selection of turbo pipes on our website and make it easy on yourself when diagnosing problems and creating accurate solutions for your car.
4. Spark Plug - As the spark plugs are related to your vehicle’s performance you really can’t ignore the damage a faulty spark plug is doing to your vehicle. Don’t think twice and replace the faulty ones today.
5. Knock Sensor - A faulty Knock Sensor can be troublesome. You can always rely on us as we have best auto parts for our customers.
6. Boost Pressure Gauge - If you need boost pressure gauge to correct your obd error code P2587 then you can simply browse through PartsAvatar Canada and get your hands on the best selection parts available.
7. Engine Control Module - Engine Control Module of your car is also known as the car’s brain. It is extremely essential to keep your vehicle’s ECM in good shape to avoid any sort of performance issues with your car. If you need one to get rid of this OBD error code P2587 then you can easily find one with us and that too at the most economical prices.

Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

• 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 end play. The excessive end play 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 P2587 Code

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