When is the Code Detected?

If the Powertrain Control Module (PCM) detects a Manifold Absolute Pressure (MAP) sensor signal voltage that is high, code P1107 will be set.

Possible Symptoms

P1108 CADILLAC Meaning

The Manifold Absolute Pressure (MAP) sensor responds to changes in intake manifold pressure. Pressure changes occur based on engine load. The MAP sensor has the following circuits:

– 5-volt reference circuit
– Low reference circuit
– MAP sensor signal circuit

The Powertrain Control Module (PCM) supplies 5 volts to the MAP sensor on the 5-volt reference circuit. The PCM also provides a ground on the low reference circuit. The MAP sensor provides a signal to the PCM on the MAP sensor signal circuit that is relative to pressure changes in the manifold. The PCM should detect a low signal voltage at low MAP, such as during idle or deceleration. The PCM should detect a high signal voltage at high MAP, such as when the ignition is ON with the engine off, or at wide open throttle (WOT). The MAP sensor is also used to determine barometric pressure (BARO). This occurs when the ignition switch is turned ON with the engine stopped. The BARO reading may also be updated whenever the engine is operating at WOT. The PCM monitors the MAP sensor signal for voltage outside the normal range.

The data is used to calculate air density and determine the engine’s mass air flow, which in turn determines the required fuel delivery for optimal combustion. A fuel-injected engine may also use a Mass Air Flow (MAF) sensor to detect intake air flow. A typical configuration uses either one or the other, but rarely both. The MAP/BARO Switch solenoid switches the air flow passage based on the voltage signal sent by the ECM.
