Check Engine Light

P0245 code definition

Turbocharger Wastegate Solenoid A Circuit Low

What the P0245 code means

P0245 is an OBD-II generic code that the engine control module (ECM) detected the turbocharger wastegate solenoid A input circuit low is below specifications, indicating a short in the solenoid or wiring.

What causes the P0245 code?

  • The turbocharger wastegate solenoid is shorted causing a low voltage or high resistance on the solenoid circuit.

  • The wastegate solenoid ground side has a short on the control side causing loss of solenoid control.

  • The solenoid connector has a corrosion buildup or a loose connection that is increasing resistance in the circuit.

What are the symptoms of the P0245 code?

  • The Check Engine Light will be illuminated and the code is set in the ECM memory.

  • The engine turbo boost will be erratic or not work at all causing low power.

  • The engine may intermittently lack some power during acceleration if the solenoid has an intermittently shorted circuit or connector.

How does a mechanic diagnose the P0245 code?

  • Scans codes and documents the freeze frame data in order to verify the problem

  • Clears the engine and ETC codes to verify the concern and that the code comes back

  • Checks the operation of the wastegate solenoid to see if it is capable of controlling vacuum to the wastegate

  • Checks for any corrosion in the solenoid connection that may cause intermittent solenoid control issues

  • Checks the solenoid to the wastegate for the proper resistance to specifications or conducts pinpoint tests

  • Checks the solenoid wiring for shorted harnesses or melted connectors

Common mistakes when diagnosing the P0245 code?

  • Failing to verify the code and problem before attempting to diagnose the code
  • Failing to verify that the harness is not shorted or melted on the exhaust or turbo

How serious is the P0245 code?

If the wastegate solenoid cannot operate the wastegate, then you will have a no boost condition in the intake manifold when the engine needs the power and this will cause the engine to have a lack of power on acceleration.

What repairs can fix the P0245 code?

  • The wastegate solenoid A is replaced for a short internally

  • The wiring connections to the solenoid are cleaned or replaced due to corrosion in the connections

  • The wiring harness is repaired and repositioned for shorted or melted wires

Additional comments for consideration regarding the P0245 code

Code P0245 is triggered by the ECM detecting the solenoid circuit having a high resistance or short which causes the solenoid not to operate. The most common cause is the solenoid having high resistance or being shorted internally.
