Parts for your 2016 Toyota Crown-Map sensor

2016 Toyota Crown MAP sensor — what it does and why it matters

Short answer: yes, the 2016 Toyota Crown does use a MAP (manifold absolute pressure)–type sensor. Toyota’s factory repair literature for the 210‑series Crown lists a Manifold Absolute Pressure sensor on the 2.5‑litre hybrid (AWS210, 2AR series) and a Turbo/Boost Pressure sensor on the 2.0‑litre turbo (ARS210, 8AR‑FTS). Both are pressure sensors read by the ECM for load and boost control. Relevant sources include: Toyota Crown (210 Series) Repair Manual — SFI System: “Manifold Absolute Pressure Sensor” and “Turbo Pressure Sensor (8AR‑FTS)”, and Toyota/Lexus technical manuals for the 8AR‑FTS (as used in Lexus IS/GS 200t), which specify an intake pressure sensor for boost regulation and fuelling.

For owners, that means the MAP/boost sensor is absolutely part of the engine management on a 2016 Crown. Its job is to report real‑time intake pressure so the ECM can juggle fuelling, ignition timing, EGR flow checks, and (on the 8AR‑FTS) wastegate/boost control. It also helps with altitude compensation, keeping the mix tidy from sea level to the mountains.

When a MAP sensor gets grumpy, the car can feel a bit off: lazy throttle response, rough idle, higher fuel use, or the odd stall. The dash may throw a code such as P0106–P0108 (MAP range/performance) or, on the turbo, P0236/P0237 for boost pressure sensor issues. Because these sensors live in a hot, sometimes oily part of the bay, contamination on the sensing port or a split vacuum/charge hose can be just as guilty as the sensor itself.

Servicing advice? There’s no set replacement interval in Toyota’s schedule, but it’s smart to check the MAP/boost sensor every service. Make sure the connector is clean and tight, look for cracked hoses, and confirm there’s no oil sludge in the port. If cleaning is needed, use only an electronics‑safe MAF/MAP cleaner — no brushes or compressed air straight into the port. On the 8AR‑FTS, also inspect the intercooler pipes and clamps so the sensor isn’t “seeing” a leak. If replacement is required, it’s a straightforward remove‑and‑refit: disconnect the battery negative, unplug the connector, undo the fasteners, swap the sensor with a quality unit, then clear codes and perform any idle/ECM relearn as per the Toyota repair manual. Torque specs vary by engine and bracket, so follow the exact figure in the service information rather than guesswork.

• Common symptoms: rough idle, sluggish take‑off, increased fuel use, hesitation, MIL on.
• Quick checks: wiring/connectors, vacuum or charge hoses, contamination at the sensor port.
• Best practice: use OEM‑quality parts and scan‑tool data (kPa vs MAF, STFT/LTFT) to confirm the fix.

Popular questions about the 2016 Toyota Crown MAP sensor

Where is the MAP/boost sensor on a 2016 Toyota Crown?

On the 2.5 hybrid, it’s mounted on or near the intake manifold with a small port into the plenum. On the 2.0 turbo, the “turbo/boost pressure” sensor sits in the intake tract between the intercooler and throttle body (varies by market spec), reading charge‑air pressure.

It’s easy to spot: a small two‑to‑three‑pin sensor with a single bolt or clip and an O‑ring seal.

What fault codes point to a bad MAP sensor on this model?

Typical codes include P0106, P0107, P0108 for MAP circuit/range, and on the 8AR‑FTS turbo models, P0236 or P0237 for boost pressure sensor performance. Always rule out wiring issues and leaks before condemning the sensor.

Live data that doesn’t track barometric pressure KOEO or shows implausible kPa at idle is another giveaway.

Can it be cleaned, or should it be replaced?

Light contamination can often be cleaned with a proper MAF/MAP‑safe spray. If there’s internal failure, water ingress, or the readings are erratic after cleaning and checks, replacement is the go.

When refitting, use a fresh O‑ring if required and follow the Toyota torque spec in the repair manual.
