P0235 is an OBD-II generic code that is triggered when the Engine Control Module (ECM) detects intake boost pressure sensor A input malfunction when compared to the manifold pressure sensor (MAP) at idle, and with the key turned on before starting the engine.
How do you fix P0238 turbocharger boost sensor A circuit high?
What repairs can fix the P0238 code?
- Replacing the boost sensor if it is shorted internally and not giving the correct input pressure reading to the ECM.
- Repairing the wiring harness if any shorts are found, and securing the harness from getting damaged.
- Replacing the broken connectors causing the shorted or open circuits.
How do you clean a turbo boost sensor?
Zitat von Youtube: Before you put the sensor back smear a little vaseline. Around the o-ring. Put the sensor back into position the reverse way to the way you got it out don't forget to make the electrical connection.
What is boost pressure sensor?
the boost pressure sensor measures the absolute pressure before the throttle valve. the engine control unit uses its signal to calculate a correction value for the boost pressure.
Where is the turbocharger boost sensor located?
The boost pressure sensor is located inside the intake pipe in front of the throttle valve. The Sensor measures the pressure and sends the data to the engine management system.
How much is a boost sensor?
The average boost pressure sensor replacement cost is between $175 and $200. However, this cost can vary depending on the vehicle you drive and where you take it for repairs.
How do you test a turbo boost pressure sensor?
1 shows a typical boost pressure sensor.
- Remove the pressure sensor from the intake manifold.
- Connect the vacuum hand pump to the pressure sensor.
- Turn on the ignition.
- Set the multimeter to “DC voltage”.
- Set the lower absolute pressure value P-low.
- Test the lower output signal U-low between pin B (2) and earth A (1).
What can cause low boost pressure?
Possible causes of low boost pressure can be broken hoses, contamination build-up within the turbine or compressor areas, leaking seals, damaged shaft bearings, the wastegate sticking open or operating incorrectly, a leak in the intercooler, a blocked air filter, a damaged diesel particle filter, or a damaged catalytic …
