P1101 Diagnostic Trouble Code (11 interpretations)

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

Chevrolet

1 interpretation
P1101
Intake airflow - incorrect Chevrolet · engine Data confidence 62%

The control module detected that the Intake airflow state or value did not match what was expected. This is the manufacturer-specific definition used by Chevrolet.

Possible causes

  • Wiring
  • mechanical fault
  • engine coolant temperature (ECT) sensor
  • barometric pressure (BARO) sensor
  • intake air temperature (IAT)sensor
  • manifold absolute pressure (MAP) sensor

Chrysler

1 interpretation
P1101
Airbag Control Module Signal Received Chrysler · airbag Data confidence 62%

The control module detected a fault associated with the Airbag Control Module Signal Received circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.

Dodge

1 interpretation
P1101
Ambient air temperature sensor - circuit high Dodge · engine Data confidence 62%

The control module detected that the signal in the Ambient air temperature circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Dodge.

Possible causes

  • Wiring
  • connectors
  • ambient air temperature sensor
  • BCM

Ford

1 interpretation
P1101
Mass Air Flow Sensor Out of Self - Test Range Ford · engine Data confidence 80%

The control module detected a fault associated with the Mass Air Flow Sensor Out of Self - Test Range 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
  • battery
  • MAF sensor
  • ECM

Recommended checks

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

Hyundai

1 interpretation
P1101
Manifold Absolute Pressure(MAP) Sensor - Abnormal Hyundai · engine Data confidence 62%

The control module registered the fault condition described as "Manifold Absolute Pressure(MAP) Sensor - Abnormal". This is the manufacturer-specific definition used by Hyundai.

Jeep

1 interpretation
P1101
Airbag Control Module Signal Received Jeep · airbag Data confidence 62%

The control module detected a fault associated with the Airbag Control Module Signal Received circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Jeep.

Land Rover

1 interpretation
P1101
Mass air flow (MAF) sensor/volume air flow (VAF) sensor - range/performance problem Land Rover · engine Data confidence 62%

The control module judged the Mass air flow (MAF) sensor/volume air flow (VAF) behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Land Rover.

Possible causes

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

P1101
Mass air flow (MAF) sensor - out of self - test range Mazda · engine Data confidence 80%

The control module detected a fault associated with the Mass air flow (MAF) sensor - out of self - test range circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mazda.

Possible causes

  • Wiring
  • MAF sensor
  • ECM

Mitsubishi

1 interpretation
P1101
Traction control vacuum solenoid - circuit malfunction Mitsubishi · engine Data confidence 80%

The control module detected improper operation of the Traction control vacuum solenoid circuit. This is the manufacturer-specific definition used by Mitsubishi.

Possible causes

  • Wiring
  • vacuum solenoid
  • ECM

Subaru

1 interpretation
P1101
Park/neutral position (PNP) switch - circuit malfunction Subaru · engine Data confidence 80%
