Parts for your 2015 Ford Fiesta-Map sensor

2015 Ford Fiesta MAP sensor — what it does and when to service it

Based on Ford technical information, the 2015 Ford Fiesta is fitted with a Manifold Absolute Pressure (MAP) sensor across its major engine options. Ford’s Workshop Manual for Fiesta (electronic engine controls section) and Motorcraft service catalogues specify a MAP sensor for the 1.0L EcoBoost turbo-petrol, 1.6L Ti‑VCT petrol, and diesel variants. On EcoBoost models there’s a MAP sensor in the intake manifold and a charge-pressure (T‑MAP) sensor in the boost piping, both feeding the PCM for accurate load and boost control.

The MAP sensor measures the absolute pressure inside the intake manifold. The Fiesta’s PCM blends that signal with intake air temperature and engine speed to calculate engine load, then sets fuel, spark and (on turbo models) boost. That’s why a healthy MAP sensor is critical for smooth idle, clean acceleration, decent fuel economy, and low emissions.

For a 2015‑Ford‑Fiesta MAP sensor, there’s no fixed replacement interval—it's “as needed.” However, as part of routine servicing, it’s smart to inspect and, if required, clean the sensor and its port. Oil mist and carbon can build up at the manifold tapping, especially on high‑kilometre cars or those mostly driven in the city. EcoBoost models can also see contamination from crankcase vapour in the charge tract.

• Check for symptoms: hard starting, rough idle, flat spots, poor fuel economy, black smoke on diesels, or a glow/engine light. Common MAP‑related DTCs include P0106, P0107 and P0108.
• Locate it: typically on or near the intake manifold, EcoBoost adds a charge‑pipe sensor near the intercooler.
• Inspect the connector and loom for chafing or corrosion, repair before blaming the sensor.
• If cleaning, use proper electronics/contact cleaner only—no oily sprays. Let it dry fully before refitting.
• If replacement is needed, use a quality part meeting Ford specifications. Fit the new O‑ring, seat it squarely, and tighten the fasteners gently to manufacturer guidance.

After any MAP‑sensor work, clear codes and take the Fiesta for a short drive so the PCM can relearn trims. If faults persist, check for vacuum leaks, split hoses, or a clogged PCV system—issues that can mimic a dud MAP reading.

Popular questions about the 2015‑Ford‑Fiesta MAP sensor

Where is the MAP sensor on a 2015 Ford Fiesta?
On most petrol models it’s mounted on the intake manifold near the throttle body. The 1.0L EcoBoost also uses a charge‑pressure (T‑MAP) sensor in the intercooler/boost pipework. Diesel versions usually have a boost/MAP sensor on the manifold or charge pipe, depending on build.

What are the symptoms of a failing MAP sensor?
Expect rough idle, hesitation, higher fuel use, lack of power, hard starting and a check‑engine light. Fault codes often include P0106 (range/performance), P0107 (low input) or P0108 (high input). Diesels may show black smoke under load. Always rule out vacuum leaks and wiring issues first.

Does the 2015 Fiesta have both a MAF and a MAP sensor?
It depends on the engine. Many EcoBoost variants run a speed‑density strategy with MAP/T‑MAP and no traditional MAF. Some naturally aspirated petrol models may have both, with the MAP assisting diagnostics and transient load calculations. Regardless, a MAP sensor is present on 2015 Fiesta models.
