Circuit Description

MAP sensor detects manifold pressure as a voltage that is supplied to ECM. Signal is used to determine basic injection duration and basic injection advance angle. ECM will operate in fail-safe mode if DTC P0106 is set. DTC is set when ECM detects MAP sensor output voltage is out of range. Possible cause is:

MAP sensor.

NOTE: If DTCs P0105 and P0106 are output together, an open may exist in MAP sensor circuit. Perform DTC P0105 circuit test before performing DTC P0106 circuit test.
