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 an open or short in MAP circuit. Possible causes are:
- MAP open or short circuit.
- MAP sensor.
- ECM.
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.
