How do I fix code P0243?
What repairs can fix the P0243 code?
- Replacing a wastegate solenoid with an open circuit.
- Repairing or replacing a solenoid wiring connection with corrosion in the pins.
What is a turbo wastegate solenoid?
A wastegate is a valve that controls the flow of exhaust gases to the turbine wheel in a turbocharged engine system. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to protect the engine and the turbocharger.
Where is the wastegate solenoid located?
The wastegate solenoid is mounted to the driver side valve cover. There are two vacuum lines entering the solenoid, one of which comes from the vacuum pump (mounted on the passenger side front of the engine) while the other runs from the wastegate solenoid to the wastegate actuator.
What happens if my wastegate is stuck open?
If it was stuck closed, you would spike most likely hard overboost. Stuck open you would be slow getting into boost(REALLY laggy) and you would run wastegate pressure.
What causes wastegate to fail?
Stress caused by an aging turbocharger or by a motorist increasing boost pressure from the turbocharger can overwhelm the spring that opens the wastegate at a specified pressure. In these case, the wastegate will flutter because the spring cannot keep the gate fully shut.
Do wastegates make a sound?
Wastegates are responsible for turbo flutter. That fluttering sound, which typically occurs when the throttle is suddenly closed, is the sound of the turbo trying to push air into the engine but failing, so the compressor blades ‘chop’ through the air.
What is the OBD II fault code p0243?
OBD II fault code P0243 is a generic code that is defined as “Turbocharger (TC) wastegate regulating valve “A” – circuit malfunction, and is set when the PCM (Powertrain Control Module) detects a malfunction in the control and/or signal circuit of the valve that regulates the operation of the turbocharger wastegate.
What does the p0242 code on an engine mean?
What the P0242 code means. P0242 is a generic OBD-II code indicating that the Engine Control Module (ECM) detected the turbocharger wastegate solenoid has an open or short circuit.
What are the symptoms of a p0243 turbocharger malfunction?
Symptoms of a P0243 engine code may include: Instrument cluster message alerting driver to condition Potential causes for this code to set are: Open in the control circuit (ground circuit) between the wastegate/boost pressure control solenoid A and the PCM
What happens when the p0234 code is set?
The Check Engine Light will be illuminated and the P0234 code will be set in ECM memory. The engine overboost condition may cause gaskets or seals to the intake or heads to fail. The engine may run normally until the excessive overboost pressure blows out a gasket or seal.
