P0105

Manifold absolute pressure (MAP) sensor circuit malfunction

Detection Conditions

• Input voltage from the manifold absolute pressure sensor is below 0.16V or above 4.9V when ignition switch is turned on.
• Engine coolant temperature is above 80 degrees C and the difference between manifold absolute pressure and atmospheric pressure is less than 6.43 kPa.

Diagnostic Support Notes

• This is a continuous monitor (CCM)
• The check engine indicator illuminates if the ECU detects the above malfunction condition during the first drive cycle
• PENDING CODE is not available
• FREEZE FRAME DATA is available
• DTC is stored in ECU memory

Possible Causes

• Manifold absolute pressure sensor malfunction
• Open or short circuit in wiring from MAP sensor terminal B and ECU
• Open or short circuit in wiring from MAP sensor terminal C and ECU
• Open circuit in wiring from MAP sensor terminal A and ECU
