2015 Toyota Crown MAP sensor — what it does and how to look after it
Yes, the 2015 Toyota Crown uses a MAP (manifold absolute pressure) sensor. Toyota’s S210-series service literature for the Crown (Repair Manual and EWD), plus the Toyota Electronic Parts Catalogue, list a Manifold Absolute Pressure sensor (also called a turbo pressure/boost sensor on the 8AR‑FTS turbo models). The same documents detail ECM diagnostics for MAP with OBD-II codes like P0106, P0107 and P0108, confirming the part is fitted across relevant petrol and hybrid variants.
The MAP sensor gives the engine computer a live read on pressure inside the intake manifold. Paired with data from the MAF and intake temperature, it helps the ECU nail fuel delivery and ignition timing, control EGR and VVT, and on the 8AR‑FTS turbo, manage boost. When the MAP is healthy, the Crown pulls smoothly, idles neatly, and sips fuel the way it should.
What goes wrong when it doesn’t? A tired or contaminated sensor can cause lazy throttle response, rough idle, stalling, hard starts, sooty exhaust, or the turbo dropping into limp mode. The check engine light will often flag a P0106, P0107 or P0108. Because those symptoms overlap with vacuum leaks or split intercooler hoses, it’s smart to scan live data before throwing parts at it.
There’s no scheduled replacement interval for the MAP sensor on this model, but it’s worth a look during regular servicing of your 2015-toyota-crown map-sensor—especially if the air filter, PCV system, or intake plumbing has seen better days. A quick visual once-over goes a long way:
- Check the sensor’s port and the manifold/charge pipe for oil sludge or carbon build-up.
- Inspect the connector and wiring for corrosion, broken clips, or chafing.
- On turbo models, make sure intercooler and vacuum lines are intact and clamped.
If the port is grimy, a careful clean with electronics-safe cleaner on the port (not soaking the electronics) can help. If readings are out of whack or faults keep coming back, replacement is the fix. Genuine or quality OEM-equivalent sensors fit and seal properly, and the job is typically a straightforward driveway task: disconnect the plug, swap the sensor and O-ring, tighten to workshop spec, clear codes, and confirm baro/idle kPa readings with a scan tool. Easy as. Keeping the intake system airtight and the air filter fresh will help the new sensor live a long, happy life around Aussie and Kiwi roads.
Popular questions about the 2015 Toyota Crown MAP sensor
Does the 2015 Crown have both MAF and MAP sensors?
Most 2015 Crown variants use both. The MAF measures incoming air mass, while the MAP tracks pressure in the manifold. On the 8AR‑FTS turbo engine, the MAP (often called a boost pressure sensor) is essential for accurate boost control.
What fault codes point to a bad MAP sensor?
Common MAP-related DTCs on this model are P0106 (range/performance), P0107 (low input) and P0108 (high input). A scan of live data can confirm if the sensor is stuck, laggy, or if there’s a vacuum/boost leak mimicking a sensor fault.
Can the MAP sensor be cleaned, or should it be replaced?
Light contamination on the sensor port can often be cleaned with electronics-safe cleaner. If readings remain implausible, the diaphragm or circuitry may be shot and the sensor should be replaced. After refit, clear codes and verify pressure readings with a scan tool.
