Parts for your 2019 Ford Ranger-Map sensor

2019 Ford Ranger MAP sensor: purpose, care and when to swap it

Yes, a MAP sensor is absolutely used on the 2019 Ford Ranger. Ford’s Workshop Manual for the 2019 Ranger (Section 303-14 Fuel Charging and Controls) and Ford service wiring diagrams list a Manifold Absolute Pressure (MAP) sensor across the 2.0‑litre Bi‑Turbo diesel, 3.2/2.2 Duratorq diesels, and the 2.3‑litre EcoBoost petrol. These engines also commonly run a second charge‑air pressure/temperature sensor (often called a T‑MAP) after the intercooler. Technical bulletins and OBD references (DTCs P0106–P0108) further support that MAP data is integral to load, boost and EGR control on this model.

On the 2019 Ranger, the MAP sensor reads the absolute pressure inside the intake manifold. The engine computer uses that pressure, plus air temperature and RPM, to work out how much air is going in so it can sort fuelling, ignition timing (on petrol), turbo boost and EGR behaviour. In short, it’s the backbone of speed‑density control, keeping the ute smooth, efficient and punchy under load whether towing or cruising down the motorway.

Because Rangers see plenty of real‑world dust, soot and oil vapour, the MAP sensor can get contaminated over time—especially on diesels with EGR. That can cause rough idle, sluggish response, black smoke (diesel), poor fuel economy, hard starts or even limp mode. Common fault codes include P0106, P0107 and P0108. A quick key‑on/engine‑off check should show the MAP reading close to local barometric pressure (about 100 kPa at sea level).

• Inspection and cleaning: every 20,000–30,000 km, or sooner if driving dusty tracks or lots of short trips. Use a plastic‑safe electronics or MAP/MAF cleaner. Don’t poke the sensing element.
• Replacement: ignition off, let it cool, unplug the connector, remove the retaining screw(s), lift out, check/replace the O‑ring, and install the new unit evenly. Use the workshop manual for the correct torque and any reset procedures.
• Good habits: keep the air filter fresh, check crankcase breather hoses, and fix boost leaks early—they all help the MAP stay clean and accurate.

Some Ranger engines may also have a MAF up near the airbox, but the MAP on the manifold is always part of the system. If readings look odd or the ute feels down on power, a quick MAP health check is cheap insurance.

Popular questions

Does the 2019 Ford Ranger have a MAP or a MAF?
All 2019 Rangers have a MAP sensor on the intake manifold. Depending on engine, they may also run a MAF up by the airbox and a second T‑MAP after the intercooler. The ECU blends these signals to control fuelling, boost and EGR. If unsure, a quick look at the intake manifold and airbox area will usually reveal the sensor lineup.

Where is the MAP sensor on a 2019 Ranger?
It’s typically bolted to the intake manifold. On the 2.0 Bi‑Turbo diesel it’s on the upper manifold near the EGR/throttle body area, on the 3.2/2.2 diesels it’s in a similar spot, on the 2.3 EcoBoost it sits near the throttle body. Many variants also have a charge‑air pressure/temperature sensor at the intercooler outlet pipe.

Can the MAP sensor be cleaned, or should it be replaced?
Light contamination can usually be cleaned with electronics‑safe MAP/MAF cleaner. If readings remain erratic, the diaphragm or electronics may be shot—replace the sensor and its O‑ring. Always follow the workshop manual for torque specs and any post‑install checks.
