P0236 Turbocharger/SuperCharger Boost Sensor \'A\' Circuit Range/Perform - General Information

Component Location





General Description

It has a function where it measures air that is flown into the intake manifold and serves this signal to the ECM. The inputted signal is computes the intake air amount, which is further used to determine the ignition timing and suitable amount of fuel to the relevant load. The MAP sensor is divided into the sensor installed the intake manifold and the sensor installed in between the intercooler and throttle body. The reason for using 2 sensors is to determine the ignition timing and suitable amount of fuel when the change of negative pressure for the intake manifold at the time where there is sudden increase or decrease in speed in after and before the throttle body.

DTC Description

ECU sends P0236 when the between 2nd T-MAP(PUT) and atmospheric pressure have a gap under the engine stop condition.
