Recommended checks

  • Perform a full module scan
  • Review freeze-frame and occurrence data
  • Inspect relevant wiring and connectors
  • Check power supplies and grounds
  • Compare commanded and measured values
  • Check applicable OEM service information

Dodge

1 interpretation
P1112
Intake Air Temperature Sensor Circuit Intermittent Low Voltage Dodge · engine Data confidence 62%

The control module detected an unstable or intermittent signal in the Intake Air Temperature circuit. This is the manufacturer-specific definition used by Dodge.

Ford

1 interpretation
P1112
Intake Air Temperature Sensor Intermittent Condition Ford · engine Data confidence 80%

P1112
Intake air temperature (IAT) sensor - intermittent sensing Mazda · engine Data confidence 80%

The control module detected a fault associated with the Intake air temperature (IAT) sensor - intermittent sensing 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
  • IAT sensor
  • ECM
