Do you know that you can get turbo boost with iobd2?
Do you know that you can get turbo boost with iobd2?
Do you know that if your car has a turbocharged engine, you can get turbo boost pressure with iOBD2 although there is no a boost gauge on iOBD2? It is easy. Simply read the MAP (Manifold Absolute Pressure) value, and then subtract 100Kpa and you will get the boost pressure. I didn’t get this idea until one of our customers sent me a message.
How does the boost control solenoid work on a turbocharger?
The PCM uses boost control solenoid to control the amount of pressure produced by the turbocharger, and simultaneously use the boost pressure sensor to verify the correct boost pressure.
How to check a turbocharger boost sensor signal?
Turn the ignition key on with engine off (KOEO) back probe the boost sensor reference wire at the sensor connector with a digital volt ohm meter (DVOM) check for 5 volts. If voltage is correct back probe the boost sensor signal wire should between .2 volts and .5 volts. If correct go to next step, if not suspect a faulty boost sensor.
Can a boost leak tester be used on a turbo?
Using a boost leak tester, you don’t need to start up the car or need to charge up the turbo. In fact, the machine does all the work by itself by pressurizing the system just like a turbo spool. All you need to do is remove the turbo inlet an attach the tester in its place.

What is the voltage of the turbo boost sensor?
When the intake manifold pressure is high due to turbo boost, sensor voltage output is 2.0-4.7 volts. The sensor receives a 5-volts reference from the ECM.
What are the symptoms of a bad boost sensor?
While the most common symptom of a bad boost pressure sensor is a check engine light, you might notice a few other issues like decreased engine performance if this happens. Below we’ve highlighted the three most common symptoms of a bad boost pressure sensor.
What’s the boost pressure on a Mercedes Benz Turbo?
The reason for this is very simple the turbo is spinning at 2750 rps (per second) at normal boost pressures and flow rates (not maximum) rpms translate to approx 165,000 per minute. The micro sensor for boost pressure is capable of up to 500 samplings per second due to the extremely rapid response of the VNT type turbos.
