P0248 code meaning
Turbocharger/Supercharger Wastegate Actuator B Range/Performance
Powertrain system Generic code P02xx codes Check engine light
What P0248 means
The wastegate lets exhaust bypass the turbine to limit boost; actuator B is either a pulse-width-modulated solenoid on a pneumatic wastegate can or an electric actuator with a position sensor. B is the second turbo or actuator, so B codes only exist on engines with two. P0248 is the counterpart of P0244: actuator B does not reach the commanded position, or boost does not respond as expected, although the circuit is electrically sound. Stellantis documents it on the 2025 Ram 1500 with the 3.0 litre Hurricane twin-turbo, often with P2B94 (position sensor B learning limit): incorrectly fitted retaining clips on the wastegate rod caused missing turbo boost. Thresholds are not published; GM and Ford do not use the code, Ford monitors actuator B position under P25B5/P25B6.
P0248 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.3 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0248
- Check engine light on
- Missing turbo boost, lack of power
- Uneven boost between the turbos
- Limp mode possible
Common causes of P0248
- Most likelyRetaining clip of the wastegate rod missing or fitted wrongly, rod unhooked
- PossibleWastegate flap B coked or sticking
- PossiblePosition sensor learned value outside limits (e.g. not relearned after turbo replacement)
- Less likelyPneumatic wastegate: control hose or can B leaking
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0248 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| 48 | The exact fault in that area. |
What to do next
- Note P0248 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 P0248
What does P0248 mean?
P0248 means "Turbocharger/Supercharger Wastegate Actuator B Range/Performance". The wastegate lets exhaust bypass the turbine to limit boost; actuator B is either a pulse-width-modulated solenoid on a pneumatic wastegate can or an electric actuator with a position sensor. It is a generic code, so it means the same on every make.
Is it safe to drive with P0248?
Drive gently and only to a workshop. With P0248 the car can go into limp mode (reduced power) to protect itself.
Will P0248 fail an emissions test?
Yes, it can. P0248 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 P0248 to fix?
Difficulty: medium. A typical repair takes 0.3 to 5 hours of work. This is a job for a workshop.
Will P0248 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
