2008 Toyota Land Cruiser MAP sensor — is it fitted and what to do about it

Based on Toyota factory service information (TIS) for the 200 Series (2008 MY) and the Engine Control System sections for both the 4.5L 1VD-FTV V8 turbo‑diesel and the V8 petrol engines (2UZ‑FE and 3UR‑FE), the 2008 Land Cruiser is equipped with a Manifold Absolute Pressure (MAP) sensor. Toyota diagnostic charts list DTCs P0105–P0108 for this component, and the Toyota Electronic Parts Catalogue (EPC) shows a manifold pressure/boost sensor mounted to the intake for these engines. Independent workshop manuals and scan‑tool data used in AU/NZ trade circles likewise reference MAP/boost readings on 2008 LC200 models. So yes — a MAP sensor is relevant and used on the 2008 Toyota Land Cruiser.

On this Land Cruiser, the MAP sensor keeps the engine computer up to speed with what’s happening inside the intake manifold. It reads absolute pressure (and, on some variants, intake air temperature nearby), letting the ECU calculate air density for fuelling, ignition timing, EGR and boost control. On the 1VD‑FTV diesel in particular, that signal is crucial for turbo boost management and smoke control, on the petrol V8s it works alongside the MAF as a sanity check and backup, and for transient load changes.

For servicing in Australia and New Zealand, there’s no fixed replacement interval — they generally last years — but they do like a clean life. EGR soot and oil mist can cake the MAP sensor port, especially on the diesel. As part of a 40–60,000 km service rhythm (or if performance drops), it’s worth removing the sensor from the manifold and carefully cleaning the sensing port with electronics-safe cleaner. Avoid poking the element, let the cleaner do the work and ensure the O‑ring seals properly on refit. After any replacement or deep clean, clear fault codes and check live data for a steady MAP reading at key-on engine-off (close to local barometric pressure) and at idle.

If the MAP sensor goes out of whack, owners may notice any of the following:

• Sluggish take-off, poor fuel economy, or excessive smoke on diesels
• Surging, rough idle or hard starting
• Check Engine Light with codes like P0105, P0106, P0107 or P0108

Replacement is straightforward: disconnect the battery if preferred, unplug the connector, remove the fixing screws, swap in the new unit with a fresh seal, reconnect and verify with a short road test. A quick scan-tool check of MAP versus ambient pressure and a boost run (diesel) will confirm it’s happy.

Where is the MAP sensor on a 2008 Land Cruiser?

It’s mounted on the intake manifold. On the 1VD‑FTV diesel, look near the top of the manifold plenum where it reads boost/pressure directly. On the petrol V8s it’s also on the manifold, typically secured with two screws and a plug — easy to spot once the engine cover is off.

Can the MAP sensor be cleaned, or should it be replaced?

Light contamination can usually be cleaned with electronics-safe cleaner. If the sensor is oil‑soaked internally, damaged, or won’t read correctly after cleaning, replace it. Always check and renew the O‑ring so it seals properly.

What fault codes point to MAP sensor issues on this model?

Common codes are P0105 (MAP circuit range/performance), P0106 (MAP performance), P0107 (low input) and P0108 (high input). These can be caused by the sensor, wiring/connectors, or a blocked port — so confirm with live data and a quick visual check before fitting parts.
