Default P1106



Manifold Absolute Pressure (MAP) sensor responds to changes
in intake manifold pressure. PCM supplies 5-volt reference and ground
for MAP sensor. MAP sensor provides a signal to the PCM relative to
pressure changes in intake manifold pressure (vacuum). A low voltage
signal, about 2 volts on VIN K or 1.5-2.5 volts on VIN 1, is sent to
PCM on signal circuit at closed throttle (high vacuum) idle. A high
voltage signal, about 4 volts or greater on both engines, is sent at
wide open throttle (low vacuum).

You likely won't notice any drivability problems.


  • MAP sensor intermittently indicates MAP greater than
    12.8 psi (0.90 kg/cm).
