<<See All OBD Codes

Is the check engine light or the service soon warning light flashing? Are you experiencing low engine acceleration and non operating turbocharger speed sensor systems? If YES, then there are chances that your vehicle is set to OBD code P2580 that indicates that something is wrong with your vehicle;s turbocharger speed sensor circuit. Let's figure it out more in the sections below.

You might be wondering what does this alien word P2580 means and how bad it affects your vehicle? Are you also wondering what is the purpose of the turbocharger in your vehicle? Well, there are many. It is designed to rotate at a speed based upon the engine’s RPM. Now, coming to error code P2580, your vehicle’s powertrain control module will set the error code P2580 when it detects an out of factory specification signals from the turbocharger speed sensor. To know more about this error code and it’s related issues take a look at the sections below.

What causes this problem with the Turbocharger Speed Sensor Circuit Low?

• Malfunctioning turbocharger speed sensor
• Open or shorted turbocharger speed sensor harnesses
• Poor electrical connections within the turbocharger speed sensor circuit

1. Powertrain Control Module - Error code P2580 flashing? Yes? Then you must check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
2. Turbocharger Speed Sensor - Reduced engine acceleration, whining or rattling noises? All of this indicates towards a faulty turbocharger speed sensor and in some cases it might lead to OBD error codes like P2580. So, don’t think twice and replace the faulty ones today.
3. Turbo Pipes - Chances are that if you are facing OBD error code P2580 your vehicle’s turbo pipes are damaged and is demanding for a quick change. So what are you waiting for? Buy new ones with us now.
4. Spark Plug - Rough and jittery idle condition? Time to replace those faulty spark plugs. Choose one for your vehicle from our extensive range of spark plugs for every make and model.
5. Knock Sensor - Does your engine face starting trouble issues? Then the knock sensor can be faulty. Get the replacement for a faulty knock sensor from PartsAvatar.
6. Boost Pressure Gauge - Are you facing OBD Error Code P2580? Don’t worry as you can fix this issue with new Boost Pressure Gauge. We care for our customers, that’s why we have Boost Pressure Gauge for every make and model.
7. Engine Control Module - Engine control module of your vehicle is your vehicle’s engine computer. If it happens to be damaged or corroded then it can lead to creating a short within the ECM, or corrosion can enter the ECM and then move to the wiring harness. This can happen even when being exposed to a wide range of elements when the car is in certain environments.

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

• To start 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 inter-cooler 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 exceed 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 waste-gate assembly and make use of the vacuum pump to manually engage the actuator valve. Carefully observe the waste-gate 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 waste-gate 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 P2580 Code

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