TORQDEX // POWERTRAIN DTC
Manifold Absolute Pressure / Barometric Pressure Circuit Low Input
The MAP or barometric-pressure sensor signal is below the expected electrical range.
00 // CODE DEFINITION
What P0107 means
P0107 indicates that the MAP or barometric-pressure signal voltage is too low.
A short to ground, sensor failure, missing reference voltage, or damaged wiring may cause the fault.
01 // COMMON SYMPTOMS
What you may notice
02 // COMMON CAUSES
What can trigger P0107?
Sensor fault
The pressure sensor may produce an abnormally low output.
Signal short to ground
Harness damage may pull the signal low.
Reference-voltage problem
Loss of the sensor supply may affect output.
03 // DRIVEABILITY
Can I keep driving with P0107?
The vehicle may remain driveable depending on the symptoms. Diagnose the fault soon, especially if performance, fuel economy, starting, shifting, or engine operation has changed.
04 // DIAGNOSTIC ORDER
Start here
Check live pressure
Look for a fixed or implausibly low pressure reading.
Verify reference voltage
Check sensor supply and ground.
Inspect the harness
Look for damaged insulation or shorted wiring.
Test sensor output
Compare signal voltage with expected pressure.
05 // COMMON REPAIR AREAS
Systems commonly involved
These are common areas associated with P0107. Testing should confirm the actual fault before parts are replaced.
Sensor fault
The pressure sensor may produce an abnormally low output.
Signal short to ground
Harness damage may pull the signal low.
Reference-voltage problem
Loss of the sensor supply may affect output.
06 // DIAGNOSTIC PRINCIPLE
Confirm the fault before replacing parts
P0107 identifies a condition detected by the vehicle control system. It does not automatically identify one failed component. Test the affected system before replacing parts.
