Do I need a wastegate on my Turbo?
While in theory you could run a turbo system without a wastegate by carefully choosing a turbo that will only reach its maximum turbine speed and desired boost pressure at the engine’s max RPM, it’s really not practical in the real world.
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 causes Mercedes Benz to run with p0170 and p0173?
If you clear the P0170 and P0173 without fixing the underlying problem those two codes will return in a couple of days. Under certain circumstances such as vacuum leaks, the car may run fine even if the CEL light is on and P0173/P0170 are present. The most common cause of P0170 and P0173 on a Mercedes-Benz is a defective mass-airflow sensor.
What does a p0243 wastegate solenoid code mean?
This code is considered to be an electrical circuit fault only. Troubleshooting steps may vary depending upon manufacturer, type of wastegate/boost pressure control, and wire colors to the control solenoid. Symptoms of a P0243 engine code may include: Instrument cluster message alerting driver to condition
What does the p0170 code on a fuel trim mean?
What the P0170 code means. The P0170 code means that the powertrain control module is detecting a fuel trim that is outside the range of specification set by the vehicle’s manufacturer.
What does p0173 mean on a check engine light?
P0173 is a diagnostic trouble code (DTC) for “Fuel Trim Malfunction (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What does p0171 and po174 mean?
A continual low voltage reading indicates a lean fuel mixture, too much oxygen. The optimal ratio is 14.7:1 (air:fuel). When your powertrain/engine control module receives a reading that indicates there’s too much oxygen and the ratio is incorrect, it sends an error code P0171 or P0174.
