10 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.

Chrysler

1 interpretation
P1108
BARO To MAP Sensor Circuit Comparison Too High Chrysler · engine Data confidence 62%

The control module detected that the BARO To MAP Sensor Circuit Comparison value was above the expected limit. This is the manufacturer-specific definition used by Chrysler.

Recommended checks

  • Perform a full module scan
  • Review freeze-frame and occurrence data
  • Confirm the exact vehicle, ECU and software context
  • Inspect relevant wiring and connectors
  • Check applicable OEM service information

Dodge

1 interpretation
P1108
Main relay - control circuit open Dodge · engine Data confidence 62%

The control module detected an interruption (open circuit) in the Main relay - control circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Dodge.

Possible causes

  • Wiring
  • connections
  • main relay
  • ECM

Ford

1 interpretation
P1108
Dual Alternator Battery Lamp Circuit Malfunction Ford · battery Data confidence 80%

The control module detected improper operation of the Dual Alternator Battery Lamp circuit. This is the manufacturer-specific definition used by Ford.

Possible causes

  • Wiring
  • alternator (upper)
  • alternator (lower)
  • ECM

Hyundai

1 interpretation
P1108
Fuel Pump Hyundai · fuel Data confidence 62%

The control module detected a fault associated with the Fuel Pump circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Hyundai.

Jaguar

1 interpretation
P1108
Manifold absolute pressure (MAP) sensor - circuit high input Jaguar · engine Data confidence 62%

The control module detected that the signal in the Manifold absolute pressure (MAP) circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Jaguar.

Possible causes

  • Wiring short to positive
  • MAP sensor
  • ECM

Nissan
