Enter your vehicle for a personalized diagnosis for code P0244

The P0244 code is a range/performance fault for the wastegate solenoid circuit, meaning the PCM recognizes the wastegate solenoid is operating but not performing within expected parameters. Unlike P0243 (a general malfunction), P0244 specifically indicates that the solenoid's response speed, duty cycle, or the resulting boost pressure doesn't match what the PCM expects to see.

This code often points to a partially failing wastegate solenoid that hasn't completely died but is sluggish or inconsistent. Vacuum supply issues — such as cracked hoses, weak vacuum signals, or contaminated vacuum lines — are also common. The wastegate actuator itself may be mechanically stiff from carbon buildup, causing delayed or incomplete response to the solenoid's commands.

The vehicle will likely experience inconsistent boost levels and may enter limp mode under heavy acceleration. While not as immediately dangerous as an overboost condition, this code indicates the turbo system cannot reliably control boost pressure. Have it inspected within a few days, as uncontrolled boost fluctuations can stress engine components and eventually lead to more expensive damage.

Symptoms

•Check Engine Light on with reduced engine power
•Inconsistent or fluctuating turbo boost
•Engine feels underpowered during acceleration
•Vehicle may go into limp mode under load
•Occasional surging or hesitation at highway speeds

Likely Causes

Wastegate solenoid operating outside expected range35%

The solenoid may be functioning but not responding within the PCM's expected parameters. Partial internal failure, carbon contamination, or weak spring tension can cause sluggish or erratic solenoid response.

Vacuum supply problems25%

Insufficient vacuum reaching the wastegate actuator — due to leaks, pinched lines, or a weak vacuum source — causes the wastegate to respond slowly or inconsistently, triggering a range/performance fault.

Wastegate actuator mechanical issues20%

A worn or sticking wastegate actuator arm, pivot, or diaphragm prevents smooth operation. Carbon buildup on the wastegate valve itself can restrict its range of motion.

Boost pressure sensor inaccuracy15%

If the boost pressure sensor provides slightly inaccurate readings, the PCM may interpret normal wastegate operation as out-of-range because the feedback loop doesn't match expected values.

Exhaust leaks near the turbocharger5%

Exhaust leaks upstream of the turbo can reduce the exhaust energy available, causing the wastegate system to behave unpredictably as the turbo struggles to build target boost.
