2020 Mitsubishi Outlander MAP sensor: purpose, fitment and care

Based on Mitsubishi workshop documentation for the GF/GG/ZL-series Outlander, the factory parts catalogue, and mainstream service data, the 2020 Mitsubishi Outlander is fitted with a manifold absolute pressure (MAP) sensor across its key variants (2.4L petrol, 2.2L diesel and PHEV). This sensor may work alongside a MAF sensor on petrol models. Technical sources referenced include:

• Mitsubishi Outlander (GF/GG/ZL) Workshop Manual – Engine Control: Sensors (MAP/Intake Manifold Pressure)
• Mitsubishi ASA Electronic Parts Catalogue – MAP sensor listings for 2020 Outlander (typical PN range 1865Axxx)
• Mitsubishi Outlander PHEV Service Information – Intake Manifold Pressure sensor function and diagnostics

On the 2020 Outlander, the MAP sensor helps the ECU figure out real-time engine load by measuring intake manifold pressure. That load signal is crucial for fuelling and ignition timing, and it’s also used to manage EGR and boost on the diesel, and to cross-check airflow on petrol models that also run a MAF. In plain terms, a healthy MAP sensor helps the Outlander start cleanly, idle smoothly, pull well up a hill, and use less fuel doing it.

Typical symptoms of a crook MAP sensor include lazy throttle response, rough idle, black smoke on diesel, higher-than-usual fuel use and a check-engine light with codes like P0106, P0107 or P0108. Because the sensor reads pressure, any split or loose vacuum hose, or an intake leak near the throttle body, can mimic a sensor fault—so it pays to check plumbing and connectors before condemning the part.

There’s no scheduled replacement interval for the MAP sensor on a 2020 Outlander, but a quick look during regular servicing—say every 30–40,000 kilometres—is smart. With the bonnet up, confirm the electrical connector is snug, the wiring isn’t chafed, and the sensor’s port and nearby hoses aren’t oily or blocked. If contamination is light, a careful external clean with electronics-safe cleaner can help, but avoid soaking the sensing element. If readings are erratic or it’s oil-soaked internally, replacement is the go. Use a quality unit with a fresh O-ring, install on a clean manifold surface, reconnect the plug, then clear fault codes and verify live data and trims on a scan tool.

Location-wise, owners will find the MAP sensor mounted on or near the intake manifold, close to the throttle body on petrol and PHEV models, the diesel places it on the manifold where it can monitor boost and EGR effects. It’s a small, inexpensive part that has a big say in how well the Outlander runs day to day.

• Does a 2020 Outlander have a MAP sensor or just a MAF?
  Most 2.4L petrol models have both a MAF and a MAP sensor, the diesel and PHEV also use a MAP sensor. The ECU uses MAP for load calculation, boost/EGR control and to cross-check airflow for accuracy.
• Where is the MAP sensor on a 2020 Outlander?
  It’s mounted on the intake manifold, usually near the throttle body on petrol and PHEV models. On the diesel, it’s on the manifold in a position that “sees” boost pressure.
• Can you drive with a faulty MAP sensor?
  You might be able to limp to a workshop, but expect poor performance and higher fuel use. Prolonged driving can foul the catalytic converter or DPF, so it’s best to sort it promptly.
