How do you fix P0238 turbocharger boost sensor A circuit high?

How do you fix P0238 turbocharger boost sensor A circuit high?

Two of the easiest solutions are:

1. Replacing internally shorted boost sensor, especially those that are not giving the right input pressure reading to the PCM.
2. Repair shorts in the wiring harness.
3. Secure harness from getting damaged.
4. Replace damaged connectors that are causing shorts or open circuits.

How do you test a turbo boost sensor?

1. Remove the pressure sensor from the intake manifold.
2. Connect the vacuum hand pump to the pressure sensor.
3. Turn on the ignition.
4. Set the multimeter to “DC voltage”.
5. Set the lower absolute pressure value P-low.
6. Test the lower output signal U-low between pin B (2) and earth A (1).

How do I know if my boost pressure sensor is bad?

Next to the check engine light, the most noticeable symptoms of a faulty turbo boost sensor are lack of engine power and poor acceleration. This is mainly caused by the ECU which disables the turbo boost to protect the engine. Other symptoms include rough idling, hesitation, and hard starting.

How much does it cost to replace a boost pressure 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. If you’re looking to replace this sensor yourself to save a little money, you can, but most of the cost is in parts, not labor.

How long does a boost sensor last?

How often do Turbocharger Boost Sensors need replacement? Boost pressure sensors are not common points of failure, and the average sensor will last well over 100,000 miles. In fact, there are replacements of these sensors ranging into the 170,000 mile range for several vehicles.

Can you clean a turbo boost sensor?

Cleaning the pressure sensor and other sensors Take the sensor out as shown above. Use an electronic cleaner to spray the sensor from a distance. Wipe it out immediately with a clean cloth.

How do I know if my turbo actuator is bad?

There are numerous symptoms of a faulty or failed actuator, including:

1. A flashing engine management light.
2. Complete loss of power, causing the vehicle to enter limp mode.
3. Intermittent low pressure.
4. Low boost.
5. Overboost.
6. Noise from the turbocharger.
7. ECU error symptoms control.
8. Fault codes.

Can a turbo car run without turbo?

Yes. The engine will still work and you will be able to drive the vehicle but it will be slower than the equivalent vehicle that doesn’t have a turbo. It won’t do any damage to drive a turbo car with no boost. Many cars have a ruptured boost pipe or a burst intercooler which means they have No boost.
