What does P0248 mean?
SAE J2012 APR2002 names P0248 Turbo/Super Charger Wastegate Solenoid "B" Range/Performance. Section 3.2 is an in-range result that is wrong for the operating point, including a stuck or skewed solenoid. P0249 and P0250 are the low and high rows on the same letter. A coil that is shorted belongs on those rows, not here.
A wastegate slope cell sits near P0244 in the 2011 GM 11OBDGS2 extract, interleaved with other monitors, and it was not clean enough to quote. That cell is also not labeled solenoid B. The Ford pneumatic note of about 34 kPa (5.0 psi) is an off-state description of one solenoid design, not a B-channel performance limit. RepairPal's command-and-vent sequence is written for an unlabeled boost-pressure solenoid. Using it as proof that 'B' failed copies an A-or-unlabeled test onto a letter the page does not assign.
Until the service information for the VIN names the B performance monitor, the supported action is to identify the solenoid and run that monitor in the state it prints. RepairPal's turbocharger boost pressure solenoid replacement, updated 3 September 2026, is $206–$241 (labor $75–$111, parts around $130). The printed pair is that national average, scoped to solenoid B because SAE J2012 names this code solenoid B range/performance. RepairPal does not label A or B. A hose, a turbo, and a wiring repair are outside the pair. Diagnosis is $125–$183 labor and is separate.
Common causes
- Solenoid B electrically in range but not producing the boost change the monitor expects
- A stuck solenoid B that still passes a resistance check
- A skewed boost result while the B circuit itself remains inside its electrical range
Symptoms
- P0248 stored
- Electrical low and high codes absent, which is consistent with section 3.2 and does not by itself name the part
- No quoted kPa-per-second limit on this page
- P0244 stored instead, which is solenoid A's performance row
Diagnostic steps
- 1.Confirm the digits are P0248. P0244 is the A performance code and keeps its own command sequence.
- 2.Locate letter B on the diagram before a rod is moved. A single-solenoid engine may not use this code at all.
- 3.Do not enter a slope from the 11OBDGS2 extract. Open the VIN monitor and use its speed window and its pressure change exactly as printed.
- 4.A resistance check with the connector off and the ignition off can pass while this row is still set. Section 3.2 is the in-range failure.
- 5.Cool the housing before any linkage is touched. Do not lever an actuator the diagram shows as a motor unless the procedure says the motor is unpowered and safe to move.
- 6.The printed pair is RepairPal's solenoid average, scoped to solenoid B. A hose, a turbo, and a wiring repair stay outside. The listing itself is not labeled B, and no slope number is quoted here.
- 7.Verify with the VIN monitor recorded, not viewed by the driver.
Repair cost
$206 – $241 (turbocharger boost-pressure solenoid B replacement, parts and labor, RepairPal national average updated 3 September 2026; a hose, a turbo, and wiring are outside this pair)
RepairPal's turbocharger boost pressure solenoid replacement, updated 3 September 2026, is $206–$241 (labor $75–$111, parts around $130). The printed pair is that national average, scoped to solenoid B because SAE J2012 APR2002 names P0248 Turbo/Super Charger Wastegate Solenoid "B" Range/Performance. Section 3.8 leaves the letter to the manufacturer. RepairPal's estimator does not label A or B, and no B-specific slope price was found. The 11OBDGS2 slope cell was not clean enough to quote and was not marked B. A hose, a turbo, and a wiring repair are outside the pair. Diagnosis is $125–$183 labor and is separate.

DIY vs shop
This is an intermediate DIY job. It usually involves diagnostic steps, specialty parts, and some careful work in tight spaces. If you have the tools and a service manual or trustworthy video for your specific vehicle, it is achievable in a weekend. Otherwise, a competent independent shop will be faster.
