2007 Toyota Land Cruiser and its MAP sensor

Based on Toyota’s factory service information for the 1HD‑FTE (diesel) and 2UZ‑FE (petrol) engine control systems, and Toyota’s Electronic Parts Catalogue (EPC), the 2007 Toyota Land Cruiser is fitted with a manifold absolute pressure (MAP) sensor. On the diesel it’s the turbo boost/pressure sensor, on the petrol it’s a vacuum/pressure sensor working alongside the MAF. Toyota diagnostic charts list MAP-related DTCs P0105–P0108 for these engines, confirming its presence and role.

On a 2007 Land Cruiser, the MAP sensor’s job is to tell the engine computer exactly how much pressure is in the intake manifold. That pressure shifts with throttle position, altitude, and—on the diesel—turbo boost. The ECU uses that signal to fine‑tune fuelling and timing, which keeps the Cruiser pulling strongly while sipping as little as practical. In the petrol V8, it also helps with EGR and knock control, in the diesel, it’s critical for boost control and smoke management.

Owners will notice a tired MAP sensor as rough idle, sluggish take‑off, higher fuel use, black smoke on a diesel, or pinging on a petrol. The check‑engine light often pops up with a P0105–P0108 code when the signal’s out of whack.

• Where it lives: typically on or near the intake manifold. On diesels it may sit near the intercooler/manifold with a short hose, on petrol V8s it’s usually bolted to the manifold close to the throttle body.
• When to look at it: every 40,000–60,000 km during routine servicing, or any time drivability goes off.

Servicing is straightforward. With the bonnet up and the key off, unplug the connector. If there’s a small vacuum/boost hose, check it for cracks, oiling, or blockages. Remove the sensor and gently clean only the port and mating area with electronics‑safe cleaner—no poking tools inside. Refit and nip the bolts to factory spec. Reconnect, then clear any codes and take a short drive so the ECU can relearn trims. On high‑kilometre diesels, oil mist can gum up the port, a clean often brings back crisp boost response. If readings remain erratic or out of spec, replacement is the go—stick with genuine or a top‑tier aftermarket unit to avoid flaky signals.

• Handy tips: keep the air filter fresh, fix any boost leaks early, and don’t pressure‑wash directly at connectors. A quick scan of live data (kPa vs RPM and throttle) is a great health check during a service.

Popular questions about the 2007 Toyota Land Cruiser MAP sensor

Where is the MAP sensor on a 2007 Land Cruiser?

It’s mounted on or near the intake manifold. On the diesel, expect it close to the manifold or intercooler piping with a short hose to the plenum. On the petrol V8, it’s usually bolted directly to the manifold near the throttle body, with a single electrical connector.

What are the symptoms of a failing MAP sensor?

Common signs include lack of power, rough idle, higher fuel consumption, black smoke on the diesel, pinging on the petrol, hard starting, and a check‑engine light with codes like P0105–P0108. Live‑data that flatlines or jumps around is another giveaway.

Should the MAP sensor be cleaned or replaced?

Start with inspection and a gentle clean of the port and any attached hose. If readings stay unstable, the housing is oil‑soaked, or DTCs return quickly, replacement is sensible. After refit, clear codes and let the ECU relearn with a short mixed drive.
