P2564 - OBD Trouble Code

<<See All OBD Codes

If you find the turbocharger to be faulty, then there is a chance that the P2564 error is stored in your vehicle. You can find this trouble code in most of the engines which are equipped with turbocharging but pops up only for a few vehicles like Hyundai and Kia. The turbo boost pressure is converted by the turbo boost control position sensor into an electrical signal for the engine computer that is PCM.

Additional information about the turbo boost pressure is sent to the PCM by the turbo boost control position sensor. In order to fine-tune the boost which is given to the given by the turbocharger, this data can be useful.

The remaining information that is needed for turbo boost pressure calculation is given to the PCM by the boost pressure sensor. If there is an electrical problem in the TBCPS, based on how the manufacturer wants to find the fault, the error code will be set by PCM. It is an electrical circuit defect which looks at the voltage signal from the TBCPS sensor to find if it is proper at the starting key on engine off. This error might have taken place due to mechanical (exhaust pressure/ intake limitations) or electrical problem (boost pressure sensor/ boost control position sensor circuit).

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

• The signal circuit to the TBCPS sensor might be shorted to the ground.
• The power circuit at the TBCPS sensor might be shorted to ground.
• It is likely for the TBCPS sensor to be faulty.
• Faulty PCM.

1. Turbocharger Boost Control Position Sensor - Repairing the defective turbocharger boost control position sensor can make your engine function normally.
2. Turbocharger - Burning excessive amounts of oil is normally a sign of a defective turbocharger. Avoid the P2564 error in the vehicle by fixing it as soon as possible.
3. Pressure Gauge - Extremely high or low temperature can damage the pressure gauge. Replace the defective pressure gauges quickly to avoid the P2564 error code.
4. Engine Control Module - If the sensor circuit is shorted it will overload the engine and damage the ECM module. If you find the engine control module to be damaged get the replacement from Parts Avatar.
5. Powertrain Control Module - The powertrain control module will monitor and compensate for any change in altitude and looks after the overall health of your car. The right replacement for your faulty powertrain control module can be found at Parts Avatar at best prices.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2564 code by mentioning some major symptoms below:

Common Symptoms

• Malfunction indicator lamp stays on.
• Performance is poor.
• Refusal during acceleration.
• The fuel economy of the vehicle might be less.

We have listed out so ways which would help you to correct the occurrence of OBD Code P2564. They are mentioned here as follows:

• Replacing the defective PCM.
• The damaged TBCPS sensor needs replacement.

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 TBCPS, PCM, turbocharger, transmission temperature, lack, engine misfire, and pressure gauge, boost pressure, RPM, spool up, knock sensor, 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:

• To start with you need a scanner, boost pressure gauge, hand-held vacuum pump, vacuum gauge, and dial indicator.
• Check for misfires or engine knock by test driving the vehicle.
• Check the turbo hose amps if they are set free, check the turbo intake as well as the intercooler connection if they are leaky or damaged.
• If these components are good, try to move the turbo onto the intake flange. If it’s not possible, every bolts and nut must be tightened as per manufacturer’s specification.
• Fix a boost gauge so that the actuating of the throttle can be seen.
• Start when the vehicle stays idle and quickly raise the engine to 5000 rpms or more and release it quickly. See if the boost gauge exceeds 19 pounds. If so, the wastegate can be stuck.
• The turbo or the exhaust system can be faulty if the boost is low.
• You will require code reader, digital volt/ohmmeter and manufacturer’s wiring diagram.
• Carefully inspect the wires and connectors and change the defective, detached, shorted or eroded parts and retest the system.
• If all the wires and connectors work properly, attach a scanner to the diagnostic port.
• Recover all the codes and freeze frame data.
• Test drive the vehicle by clearing the codes.
• There may be an erratic condition if the code does not return.
• Detach the actuator arm from the wastegate assembly.
• Manually engage the actuator valve with the help of a vacuum pump. Look closely if the wastegate opens and closes. If it doesn’t close fully, the boost pressure might drop drastically.

Turbocharger malfunction.

• Remove the turbo outlet hose while the engine cools down and look inside the unit.
• Check the unit for impeller fins which might be defective or missing and look for indications which the impeller blades might be rubbing the inner side of the housing.
• Check for oil in the housing.
• Rotate the blades with hand and listen if there is any noise or free bearings. These symptoms indicate a faulty turbocharger.
• Fix the dial indicator on the turbine outlet shaft and check the lash and endplay.
• If you don’t find any problem with the turbo or wastegate, find a constant supply of vacuum at the intake manifold and fix a vacuum gauge.
• While the vehicle is idle or in good working condition, the order must lie between 16 and 22 inches of vacuum. The catalytic converter can be bad if the vacuum is less than 16 inches.
• If there is no other problem, the wires, sensors, and connectors of the turbocharger boost sensor must be re-tested.
• Repair or replace as needed and check for the voltage and resistance values.

Common Mistakes When Diagnosing The P2564 Code

• Malfunctioning of the powertrain control module.
• Damaged turbocharger vane position sensor.
• Problematic electrical wires.
