OBD-II trouble code
P0247: Turbocharger/Supercharger Wastegate Solenoid "B"
SAE J2012 APR2002: wastegate solenoid B. The pneumatic 34 kPa note and PIP5812B name solenoid hardware without a B letter. The printed pair is RepairPal's boost-pressure solenoid, scoped to solenoid B. Wiring is outside it.

What does P0247 mean?
SAE J2012 APR2002 names P0247 Turbo/Super Charger Wastegate Solenoid "B". Section 3.8 says the letter is assigned by the manufacturer, starting at A. P0243 is solenoid A. P0248, P0249, and P0250 are this letter's range/performance, low, and high rows. A second solenoid exists only when the diagram shows one.
The hardware notes that were found do not use the letter B. Ford Tech Tips volume 2, number 2, 2020, describes one pneumatic solenoid that is free-flowing when off and limits boost to about 34 kPa (5.0 psi), and an H-bridge stepper as a different control. GM PIP5812B cleans one wastegate regulator solenoid for P0234 and P0299 on a listed set of single-turbo engines, at 15–20 PSI (103 kPa). PIP5495B's solenoid-port replacement is conditioned on P0299 on the 1.4L LUV/LUJ list. None of those documents prints P0247. Putting the 34 kPa limit, the 15–20 PSI air test, or the 1.4L port repair on 'solenoid B' invents an assignment the pages do not make.
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 P0247 wastegate solenoid B. RepairPal's page does not split A and B, and it says not every turbo uses this solenoid. The Ford 34 kPa note, PIP5812B, and PIP5495B do not identify B, so they are not the reason for the price. A wiring repair is outside the pair. Diagnosis is $125–$183 labor and is separate.
Common causes
- An open wire in the solenoid-B control circuit
- A short in that circuit, when the calibrator files it on this general row rather than on P0249 or P0250
- Solenoid B not responding to its command
- A connector or terminal on the solenoid-B circuit
Symptoms
- P0247 stored
- Solenoid B not responding when it is commanded
- P0249 or P0250 stored when the low or high split is the row the calibrator used
Diagnostic steps
- 1.Count the wastegate solenoids on the diagram and read the letter the calibrator stored. Section 3.8 does not place B on a bank.
- 2.If the stored code is P0243, P0245, or P0246, use those pages. Their tests were not written for P0247.
- 3.Do not regulate shop air into a solenoid at 15–20 PSI (103 kPa) for this code. That step is PIP5812B, for P0234 and P0299, on the models that bulletin prints.
- 4.Do not use about 34 kPa (5.0 psi) as a B-solenoid pass. It is the off state of one pneumatic design in the Ford tip.
- 5.The printed pair is RepairPal's solenoid average, scoped to solenoid B. Wiring is outside it. The listing itself is not labeled B.
- 6.Verify by the code number, not by a vent command that was documented for an unlabeled solenoid.
Repair cost
$206 – $241 (turbocharger boost-pressure solenoid B replacement, parts and labor, RepairPal national average updated 3 September 2026; wiring is 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 P0247 Turbo/Super Charger Wastegate Solenoid "B". Section 3.8 leaves the letter to the manufacturer. RepairPal's estimator does not label A or B, and it says not all turbocharged vehicles use this solenoid. Ford Tech Tips volume 2, number 2, 2020, PIP5812B, and PIP5495B do not identify solenoid B, so their tests are not this price. Wiring is outside the pair. Diagnosis is $125–$183 labor and is separate. The boost-sensor average of $236–$273 is a different line.

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.
