P0106 on Ford
MAP/Barometric Pressure Circuit Range/Performance
P0106 on Ford vehicles indicates map/barometric pressure circuit range/performance. Au7o has documented this code across 1 Ford model — most commonly on Escape. P0106 means the manifold absolute pressure (MAP) or barometric pressure sensor signal is out of the expected range or not matching engine operating conditions (range/performance). The MAP sensor measures intake manifold pressure/vacuum, which the computer uses to gauge engine load and calculate the correct fuel and ignition timing. When the reading is implausible — too steady, not tracking throttle changes, or inconsistent with other sensors — the computer flags this code. Symptoms often include rough idle, hesitation, poor fuel economy, or a lack of power, and the cause may be the sensor, a vacuum leak, or wiring.
Common Causes of P0106
- •Faulty MAP sensor
- •Vacuum leak or disconnected/cracked vacuum line to the sensor
- •Clogged or restricted MAP sensor port
- •Wiring or connector problems in the sensor circuit
- •Intake manifold leak affecting pressure readings
- •Restricted air intake or exhaust affecting manifold pressure
- •Poor ground or reference voltage to the sensor

- Engine Wiring Harness Splice to the MAP Sensor Loses Compression — Hesitation and Stalling (Recalls 14V495 / 15V813, Ford 14S17)2013
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.

What does P0106 mean on Ford?▼
P0106 stands for "MAP/Barometric Pressure Circuit Range/Performance." P0106 means the manifold absolute pressure (MAP) or barometric pressure sensor signal is out of the expected range or not matching engine operating conditions (range/performance). The MAP sensor measures intake manifold pressure/vacuum, which the computer uses to gauge engine load and calculate the correct fuel and ignition timing. When the reading is implausible — too steady, not tracking throttle changes, or inconsistent with other sensors — the computer flags this code. Symptoms often include rough idle, hesitation, poor fuel economy, or a lack of power, and the cause may be the sensor, a vacuum leak, or wiring. On Ford specifically, this code is documented across 1 model.
What causes P0106 on Ford vehicles?▼
Common causes on Ford: Faulty MAP sensor, Vacuum leak or disconnected/cracked vacuum line to the sensor, Clogged or restricted MAP sensor port, Wiring or connector problems in the sensor circuit, Intake manifold leak affecting pressure readings. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0106 on a Ford?▼
Repair costs vary widely depending on the root cause and specific Ford model.
Which Ford models have P0106 documented?▼
