What P2580 means
P2580 says the signal from turbocharger or supercharger speed sensor A stays at the low end, so the engine computer sees too little or no usable pulse activity - typically from a short to ground, a weak sensor or a pickup that cannot read the target. A Stellantis STAR case from November 2023 for 2022-2024 Ram 2500 to 5500 trucks reports P2580 with the warning lamp, sometimes after few miles; besides the normal circuit tests it asks the technician to pull the sensor and inspect bore and tone wheel with a borescope, since debris or an extra O-ring left in the bore spoiled the signal. P2581 is the high-side counterpart, P2579 an implausible speed with a working circuit. Boost is often reduced.
P2580 at a glance
- Check engine lightYes, usually on

- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2580
- Malfunction indicator lamp on
- Turbo speed reads zero or very low in live data
- Possible boost limitation and reduced power
Common causes of P2580
- Most likelyDebris on the tone wheel or an extra O-ring in the sensor bore
- PossibleSignal wire shorted to ground
- PossibleSpeed sensor A with weak or missing output
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2580 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 80 | The exact fault in that area. |
What to do next
- Note P2580 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2580
What does P2580 mean?
P2580 means "Turbocharger/Supercharger Speed Sensor A Circuit Low". P2580 says the signal from turbocharger or supercharger speed sensor A stays at the low end, so the engine computer sees too little or no usable pulse activity - typically from a short to ground, a weak sensor or a pickup that cannot read the target. It is a generic code, so it means the same on every make.
Is it safe to drive with P2580?
Drive gently and only to a workshop. With P2580 the car can go into limp mode (reduced power) to protect itself.
Will P2580 fail an emissions test?
Yes, it can. P2580 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2580 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P2580 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
