12 manufacturer-specific interpretations across 11 manufacturers in the TuningBot DTC database.

BMW

1 interpretation
P1100
Fuel pump - temperature too high BMW · fuel Data confidence 62%

The control module detected that the Fuel pump - temperature value was above the expected limit. This is the manufacturer-specific definition used by BMW.

Possible causes

  • Wiring
  • fuel pump

Ford

1 interpretation
P1100
Mass Air Flow Sensor Intermittent Ford · engine Data confidence 80%

The control module detected a fault associated with the Mass Air Flow Sensor Intermittent circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.

Possible causes

  • Wiring
  • MAF sensor

Recommended checks

  • Perform a full module scan
  • Review freeze-frame and occurrence data
  • Compare commanded and measured values
  • Check applicable OEM service information

Kia

1 interpretation
P1100
Manifold absolute pressure (MAP) sensor - for EGR system - circuit malfunction Kia · emissions Data confidence 62%

The control module detected improper operation of the Manifold absolute pressure (MAP) sensor - for EGR system circuit. This is the manufacturer-specific definition used by Kia.

Possible causes

  • Wiring
  • MAP sensor

The control module detected improper operation of the Mass air flow (MAF) sensor/volume air flow (VAF) circuit. This is the manufacturer-specific definition used by Land Rover.

Possible causes

  • Wiring
  • supply voltage
  • ground connection
  • MAF sensor
  • ECM

Lexus

1 interpretation
P1100
Barometric pressure (BARO) sensor - circuit malfunction Lexus · engine Data confidence 80%
