|Description: Manifold absolute pressure (MAP) sensor operating voltage is below the minimum calibrated parameter of 0.25 volt.
Possible Causes: • Open in the circuit, or short to ground
• VREF circuit open, or short to ground
• Damaged MAP sensor
Diagnostic Aids: The VREF voltage should be between 4.0 and 6.0 volts.
