P0244 - TURBOCHARGER WASTEGATE SOLENOID A CIRCUIT RANGE / PERFORMANCE

The PCM (Powertrain Control Module) manages the supercharging pressure of the engine. It does this through the outflow circuit to the “A” discharge pressure control solenoid.

If there is a problem with the full boost range or engine performance, the PCM activates the P0244 OBDII DTC code and turns on the Check Engine light.

• MIL light illumination.
• The engine may lock up at idle.
• Loss of engine power.

The P0244 OBD2 diagnostic code is set when one or more of the following occurs:

• The ground circuit between the discharge pressure control solenoid to the Powertrain Control Module could be short-circuited.
• Perhaps the circuit supplying power between the discharge pressure solenoid A and the PCM is shorted.
• Unloading pressure solenoid “A” could be faulty.

The steps you should follow to troubleshoot the problems corresponding to the P0244 OBDII fault code are:

• Check for Technical Service Bulletins.
• You should inspect all connectors as well as the solenoid wiring. Look for wear or friction on the connectors. Also, verify the terminals of the connectors for corrosion. If you find problems you should repair or replace them.
• Measure the resistance level of the A discharge pressure solenoid. Replace the solenoid if it does not match the technical data given in the manufacturer's service manual.
