2007 Toyota Blade MAP sensor: purpose, care, and when to replace

Based on Toyota technical literature, the 2007 Toyota Blade does use a manifold absolute pressure (MAP) sensor. Toyota New Car Features (NCF) for the E150 platform, the Toyota Repair Manual (Engine Control – 2AZ-FE and 2GR-FE), and the Toyota Electronic Parts Catalogue (models AZE156H and GRE156H) all identify a MAP sensor fitted to the intake manifold. DENSO catalogues also list compatible MAP sensors (e.g., 89421-0D010/0E010) for these engines. So, on a 2007 Blade—whether it’s the 2.4-litre 2AZ-FE or the 3.5-litre 2GR-FE—the MAP sensor is very much relevant and part of the engine management system.

What does it do? The MAP sensor measures the absolute pressure inside the intake manifold. The engine ECU uses that signal, alongside the mass air flow (MAF), throttle position, intake air temperature and engine speed, to calculate load and the right fuel and ignition timing. It helps with altitude compensation, smooth tip-in throttle response, and keeps the tune tidy under different driving conditions. On these Toyotas, the ECU also cross-checks MAF and MAP for diagnostics, so a dodgy MAP can throw drivability out even if the MAF looks fine.

Common signs it’s not happy include rough idle, sluggish take-off, surging, pinging under load, sooty exhaust, higher fuel use, and a check-engine light with codes like P0106, P0107 or P0108. Location-wise, it’s bolted to the intake manifold near the throttle body with a small O-ring seal—easy to spot once the engine cover’s off.

Servicing is straightforward. While the sensor element isn’t a regular “service item”, it pays to check it during routine maintenance, especially if there’s oil mist from the PCV system.

• Gently clean the manifold port and sensor tip with electronics-safe cleaner if there’s oily residue—don’t scrub the element.
• Inspect the connector pins for corrosion and the loom for chafing.
• Replace the O-ring if the sensor’s been out, vacuum leaks will skew readings.
• If faults persist, fit a quality OEM-equivalent (DENSO) sensor, clear codes and let the ECU relearn with a short idle and mixed drive.

For DIY replacement: disconnect the plug, remove the single retaining bolt, ease the sensor out, swap the seal, reinstall and reconnect. No special tools, and under the bonnet time is usually 10–20 minutes. Good gear, good seal, and the Blade will run sweet as.

• Does a 2007 Toyota Blade have both a MAF and a MAP sensor?
  Yes. Toyota’s NCF and Repair Manual note that the ECU uses both. The MAF measures incoming air mass, while the MAP tracks manifold pressure. The ECU cross-checks them for accuracy and fault detection.
• Where is the MAP sensor on a 2007 Blade?
  On both 2AZ-FE and 2GR-FE engines, it’s mounted to the intake manifold near the throttle body, sealed with a small O-ring and held by a single bolt. Remove the engine cover to see it clearly.
• Can the Blade run with a failed MAP sensor?
  It may start and run in a limp or fallback mode, but expect rough idle, poor economy and possible stalling. It’s best to diagnose and replace promptly to avoid further hassles and failed rego emissions checks.
