Open circuit in the sensor's signal wire, or in its power or ground (OBD-Codes.com rates these most likely; RepairPal lists a wiring issue). Signal wire shorted to voltage or to ground (OBD-Codes.com). Failed boost control / vane position sensor (both sources). Mechanical boost problems such as exhaust restriction, a wastegate issue, a bad turbo or intake leaks (OBD-Codes.com). Failed PCM, which OBD-Codes.com calls unlikely (both sources list it).

Repair damaged wiring or a corroded connector at the sensor. Fix a mechanical boost problem (exhaust restriction, wastegate, intake leak or turbo fault) if boost tests low. Replace the boost control / vane position sensor if power, ground and signal circuits test good.

P2563: Turbo Boost Control Position Sensor (Meaning, Causes, Fixes)

Q: What does P2563 mean?

P2563 means the engine computer is not getting a believable signal from the sensor that reports the turbocharger's boost control position (on many engines, the variable-geometry vane position). Wiring and connector faults are the most likely causes, followed by a failed sensor. Mechanical boost problems can also set it, so check boost before replacing parts. Many turbocharged engines, especially diesels with variable-geometry turbos, have a sensor that tells the engine computer (PCM) where the turbo's boost control mechanism actually is. RepairPal explains that the PCM moves the turbo vanes with a vane position solenoid and uses the vane position sensor to confirm they moved as commanded; if that sensor fails to report back correctly, P2563 is stored. OBD-Codes.com describes the same part as the Turbo Boost Control Position Sensor (TBCPS), usually screwed or bolted into the turbo housing, and says the PCM also checks its voltage at key on, engine off. Sources word the code slightly differently: OBD-Codes.com calls it "Circuit Range/Performance," while RepairPal's page title says "Circuit" (the same wording RepairPal uses for P2562). OBD-Codes.com also notes that, although P2563 is described as an electrical fault, it can be set by mechanical problems such as exhaust back pressure or intake restrictions. OBD-Codes.com says it shows up more often on certain Hyundai and Kia vehicles, though any turbocharged OBD-II vehicle can set it.

Q: Can I keep driving with P2563?

Drive with caution, fix soon. RepairPal rates P2563 moderate: it may not threaten safety or drivability right away, but it should be diagnosed within a reasonable time. Expect weak boost, hesitation and poorer fuel economy. Drive gently and avoid situations where you need full acceleration (merging, passing, towing) until it is fixed. If the turbo starts making grinding, whining or screeching noises, or you see heavy smoke, stop driving and have it towed.

Drive with caution, fix soon

RepairPal rates P2563 moderate: it may not threaten safety or drivability right away, but it should be diagnosed within a reasonable time. Expect weak boost, hesitation and poorer fuel economy. Drive gently and avoid situations where you need full acceleration (merging, passing, towing) until it is fixed. If the turbo starts making grinding, whining or screeching noises, or you see heavy smoke, stop driving and have it towed.

Common symptoms

Likely causes

Roughly most to least common, based on the sources below. Your vehicle may differ.

Open circuit in the sensor's signal wire, or in its power or ground (OBD-Codes.com rates these most likely; RepairPal lists a wiring issue)
Signal wire shorted to voltage or to ground (OBD-Codes.com)

Diagnostic steps you can do

⚠ Before you start

Work on a cool engine, parked on level ground with the parking brake set. Never work under a car supported only by a jack.

Look up technical service bulletins (TSBs) for your year, make, model and engine first. The problem may have a known fix.
Find the sensor (usually on the turbocharger housing) and inspect its connector and wiring for chafing, bare wires, burn marks or melted plastic.
Unplug the connector and check the terminals for burning or green corrosion. Clean with electrical contact cleaner, let dry, and apply dielectric grease.
Clear the code with a scan tool and see whether it returns. If it stays away, the connection was likely the problem.
If it comes back, OBD-Codes.com recommends confirming actual boost with a mechanical gauge against the manufacturer's spec before testing or replacing the sensor.

Typical fixes

Repair damaged wiring or a corroded connector at the sensor
Fix a mechanical boost problem (exhaust restriction, wastegate, intake leak or turbo fault) if boost tests low
Replace the boost control / vane position sensor if power, ground and signal circuits test good
Replace and program the PCM only after everything else is ruled out (OBD-Codes.com notes a replacement PCM must be programmed to the vehicle)

Repair costs vary widely by vehicle, region, parts brand and shop, so we don't quote prices. Get a written estimate after diagnosis.

🛠 When to call a pro

Circuit testing with a voltmeter needs the manufacturer's specs and wire identification (OBD-Codes.com notes the supply can be 5 or 12 volts depending on the vehicle)
Boost pressure testing with a mechanical gauge, or diagnosing variable-geometry turbo vanes and actuators
Any case pointing to a failed PCM, which must be programmed to the vehicle

FAQs

Is P2563 the same as P0299?

No. P0299 means actual boost is below what the engine asked for. P2563 points at the sensor that reports the turbo's boost control (vane) position. They often show up together, because a faulty position signal or a sticking turbo can also cause low boost.

Does P2563 mean I need a new turbo?

Usually not first. OBD-Codes.com lists wiring opens as the most likely cause and a failed sensor as possible. Check wiring and boost pressure before considering the turbo itself.

Will P2563 clear by itself?

RepairPal says codes can clear once the computer no longer detects the problem, but if it stays it should be diagnosed to avoid a more serious problem.
