What are the symptoms of an error code p0236?
The usual symptoms of this error code are: Check Engine light illuminated. PCM turned off the engine turbo boost, causing lack of power to the engine. Lack of power on acceleration if boost sensor is failing to register to right amount of boost pressure.
How to check boost pressure on DTC p0236?
If the DTC P0236 returns, and you’ve ensured that there are no engine problems or leaks in the intake / forced-induction system, you can check boost pressure. Connect a boost pressure gauge and watch its reaction as you snap the throttle to around 5,000 rpm and then release it.
What to do if you get an error code P236?
As with other trouble codes, mechanics start their troubleshooting for this Error Code P236 by scanning and documenting the freeze frame data to verify the problem. Then, the mechanic will clear the codes to check whether the error code comes back. Then, they will check the operation of the boost pressure sensor and compare it to the MAP sensor.
Can a MAP sensor read both vacuum and pressure?
In other words, a MAP sensor with the engine off will read 100 kPa, while a vacuum-boost sensor will read 0 kPa. That way, a forced-induction engine ECM can read both vacuum and pressure, depending on whether or not the turbocharger or supercharger is active.
