P0244: Turbocharger Wastegate Solenoid A Range/Performance Fault

Reduced engine power and boost pressure with possible limp mode activation

Overview

OBD2 P0244 indicates a fault in the turbocharger wastegate solenoid A circuit where the PCM detects range or performance outside expected parameters leading to reduced boost and power.

Common Symptoms

  • Check engine light illuminated
  • Reduced acceleration and engine power
  • Lower than expected boost pressure
  • Possible limp mode or engine derate

Most Common Causes

Faulty turbocharger wastegate solenoid high

Primary component monitored by PCM; common electrical/mechanical failure.

Wiring or connector issues in solenoid circuit high

Open, shorted or corroded wiring can cause out‑of‑range signals.

Vacuum or boost hose leaks affecting wastegate control medium

Leaks can prevent correct actuator movement resulting in performance errors.

Wastegate actuator or mechanical binding medium

Mechanical restrictions can mimic electrical circuit faults.

PCM/ECU internal fault or software calibration error low

Least likely; requires elimination of other causes first.

Diagnostic Steps

  1. Connect a professional OBD‑II scanner and confirm code P0244
    Expected: P0244 present in stored codes
    Interpretation: Verifies initial fault before proceeding
  2. Perform visual inspection of solenoid wiring and connectors
    Expected: No damage, corrosion, or disconnections
    Interpretation: Wiring issues may trigger code if anomalies are found
  3. Check wastegate solenoid resistance with multimeter
    Expected: Resistance within manufacturer specs
    Interpretation: Open or shorted solenoid indicates replacement
  4. Inspect vacuum/boost hoses for leaks or disconnections
    Expected: Hoses intact with no leaks
    Interpretation: Leaking hoses can affect boost control
  5. With ignition on, measure voltage at solenoid power and ground
    Expected: 12V power and good ground only when commanded
    Interpretation: Incorrect readings suggest wiring or PCM issue
