- Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage



DTC P0108



- Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage



Diagnostic Fault Information



Typical Scan Tool Data



Circuit Description



The manifold absolute pressure (MAP) sensor has a 5 V reference circuit, a low reference circuit, and a signal circuit. The engine control module



(ECM) supplies 5 V to the MAP sensor on the 5 V reference circuit, and provides a ground for the low reference circuit. The MAP sensor provides



a voltage signal to the ECM on the signal circuit relative to the intake manifold pressure changes.



Conditions for Running the DTC



* DTC P0697 is not set.



* The engine is running.



* This DTC runs continuously within the enabling conditions.



Conditions for Setting the DTC



P0107



The ECM detects that the MAP sensor voltage is less than 0.20 V for more than 5 s.



P0108



The ECM detects that the MAP sensor voltage is more than 4.80 V for more than 5 s.



Action Taken When the DTC Sets



DTCs P0107 and P0108 are Type B DTCs.



Conditions for Clearing the MIL/DTC



DTCs P0107 and P0108 are Type B DTCs.
