P0107 on Ford: How to Diagnose & Fix
Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

P0107 on Ford by model: symptoms, diagnosis and fix
The engine wiring harness splices that feed the Manifold Absolute Pressure (MAP) sensor were crimped with insufficient compression on 2013 Escapes built January 11, 2012 through April 1, 2013. The loose splice sends an incorrect MAP signal to the powertrain control module, and the PCM responds with hesitation, a rough or unstable idle, or an outright stall — often with no stored code that points at the harness, because the sensor itself tests good. Ford recalled the vehicles under 14S17 (NHTSA 14V495000), then had to re-recall them as 14S17-S1 (NHTSA 15V813000) when the first remedy did not hold, extending coverage to 2013-2014 Focus ST as well. This is an electrical-connection defect and is completely separate from the 1.6L coolant intrusion and cylinder-head cracking issues that dominate this generation, though it affects many of the same cars.
Common Symptoms
- Engine hesitates or bucks under light throttle
- Engine stalls at idle or when coming to a stop
- Rough or hunting idle
- Check engine light with fuel-trim or MAP-related codes, or no code at all
- Symptom is intermittent and worse when the engine is warm
How to Fix
Free recall remedy under NHTSA 15V813000 / Ford 14S17-S1 — the dealer cuts out the original crimped splices and installs new splices in the engine wiring harness at no charge. If the car had the first version of the repair (14S17 / 14V495000) it still needs the 14S17-S1 re-repair, so check the VIN even on a car with a recall already logged. If the stall persists after the splice repair, have the MAP sensor and the harness pigtail load-tested with the engine warm rather than replacing the PCM.

Frequently asked questions
What does P0107 mean on a Ford?
P0107 stands for "Manifold Absolute Pressure/Barometric Pressure Circuit Low Input." The PCM detects an abnormally low voltage signal from the MAP (or barometric pressure) sensor circuit, below the minimum expected threshold. This usually points to a wiring or sensor fault rather than a true pressure reading. Drivers may experience hard starting, rough idle, poor fuel economy, and stalling. On Ford it is documented across 1 model: Escape.
What are the most common causes of P0107?
The most common causes of P0107 are: Faulty MAP sensor, Open or short to ground in the MAP signal wire, Poor or corroded connection at the MAP sensor, Damaged or disconnected reference voltage circuit, Bad sensor ground, Failed PCM (rare). The specific cause varies by vehicle.
How much does it cost to fix P0107 on a Ford?
Repair costs vary widely with the root cause and Ford model; each issue on this page carries its own estimate where one is published.
