P0107 — Instant Answer
MAP/BARO Sensor Circuit Low Input
Severity: MEDIUM SEVERITY
Meaning: MAP sensor voltage is below the expected minimum. The ECM sees this as extremely high vacuum, causing incorrect fuel calculations.
Safe to drive? Usually yes with caution, but confirm root cause before long trips.
Estimated repair cost: $20 - $80
Most common causes:
- 1. Faulty MAP sensor (35-45% of cases)
- 2. Short in sensor wiring (10-25% of cases)
- 3. Bad ground connection (10-25% of cases)
- 4. ECM issue (5-10% of cases)
Common Causes
How to Diagnose P0107
- 1Check sensor wiring and connector
- 2Measure MAP sensor output voltage
- 3Verify reference voltage (5V)
- 4Replace sensor if output stuck low
