Parts for your 2011 Ford Falcon-Map sensor

2011 Ford Falcon MAP sensor — what it does, where it lives, and how to look after it

Based on the Ford FG/FG MkII Workshop Manual (Section 303-14A: Electronic Engine Controls), factory wiring diagrams, and common dealership practice in AU/NZ, the 2011 Ford Falcon runs a Manifold Absolute Pressure (MAP) sensor on all 4.0‑litre Barra six variants, including naturally aspirated, EcoLPi LPG, and XR6 Turbo. The XR6 Turbo uses a combined temperature/pressure “T‑MAP” sensor on the intake. These engines are speed‑density systems with no MAF, so the MAP signal is essential for fuelling and spark. This setup is also documented in trade references like Gregory’s/Max Ellery manuals for BA–FG Falcons and Bosch sensor guidance used by Ford.

On this Falcon, the MAP sensor measures the pressure in the intake manifold so the ECU can calculate engine load. That data drives fuel delivery, ignition timing, EGR strategy (where fitted), idle control, and on turbo models, boost monitoring and overboost protection. It also helps with altitude/barometric adjustments during key‑on.

It’s not a scheduled replacement item, but it benefits from a bit of love during regular servicing. Keep the vacuum port and surrounding manifold passage free of oil mist and sludge, and make sure the O‑ring seal is in good nick. Avoid spraying cleaners directly into the sensor—wipe the port and seat instead. If the car’s chewing more fuel than normal, idling rough, pinging, struggling for boost, or throwing fault codes like P0106–P0108, the MAP should be high on the check list.

• Typical signs it’s unhappy: lazy throttle response, sootier exhaust, stalling at lights, and limp mode on turbo models.
• Quick checks: inspect the connector for green crusties or loose pins, confirm the hose/manifold port isn’t blocked, and verify the O‑ring isn’t split or flattened.
• Replacement is straightforward: unplug, remove the retaining screw, ease the sensor out, fit a fresh O‑ring, and gently nip the screw back in. Clear codes and verify live data at idle and under light load.

Location tips: on the naturally aspirated and EcoLPi six, the MAP sits on the intake manifold near the throttle body. On the XR6 Turbo, the T‑MAP is mounted on the upper intake plumbing after the intercooler so it can see true manifold boost and charge temperature.

Look after the MAP and the Falcon rewards with smooth drivability, better economy, and rock‑solid boost control on the turbo cars.

Popular question: Where is the MAP sensor on a 2011 Falcon?

On the NA and EcoLPi 4.0, it’s on the intake manifold near the throttle. On the XR6 Turbo, it’s a T‑MAP on the manifold/intake tube post‑intercooler. Access is usually simple with basic hand tools.

Popular question: What are the symptoms of a failing MAP sensor?

Expect poor fuel economy, rough idle, hesitation, black smoke on acceleration, and for turbo models, inconsistent boost or limp mode. The ECU may log P0106, P0107, or P0108. Always rule out vacuum leaks and wiring faults first.

Popular question: Does the 2011 Falcon use a MAF as well?

No for the 4.0‑litre Barra engines. They’re speed‑density and rely on the MAP (and on turbo models, a T‑MAP). That’s why manifold pressure and intake temp readings are so critical for tune and drivability.
