2011 Honda Odyssey MAP sensor: purpose, care and when to replace

Yes, the 2011 Honda Odyssey is fitted with a MAP (Manifold Absolute Pressure) sensor. This is confirmed by Honda’s factory service information that details DTCs P0106–P0108 for the MAP circuit, as well as OEM parts catalogues listing the “Sensor, MAP” (commonly referenced as 37830-RNA-A01) mounted on the intake manifold. Aftermarket service databases also describe the Odyssey’s speed-density control strategy that relies on MAP input rather than a separate mass-airflow meter.

The MAP sensor measures pressure inside the inlet manifold so the ECU can work out engine load, then calculate fuel delivery and ignition timing to keep the V6 running smoothly and efficiently. On this Odyssey, it’s a key player for cold starts, throttle response and fuel economy, and it also helps with emissions control.

There’s no fixed replacement interval, but the sensor should be checked during routine servicing. Under the bonnet, it’s located on the top of the intake manifold near the throttle body, with one electrical plug and a sealing O-ring. A quick visual once-over for cracked wiring, a perished O-ring, or oil vapour contamination is worthwhile, especially on higher-kilometre vehicles.

Common clues the MAP sensor needs attention include:

• Check Engine Light with codes P0106, P0107 or P0108
• Rough idle, sluggish take-off, or flat spots under load
• Noticeable increase in fuel use or a rich exhaust smell

If cleaning is needed, use an electronics-safe or MAP/MAF-specific cleaner only—never harsh solvents. Let it dry fully before refitting. If replacement’s on the cards, choose a quality OEM-equivalent unit and install a fresh O-ring. The mounting screws only need to be snugged to factory spec—don’t over-tighten. If the battery is disconnected, perform an idle relearn so the ECU can settle back in.

Before condemning the sensor, rule out vacuum leaks, brittle connectors, or PCV-related oil carryover, as these can skew readings. When everything’s right, the Odyssey rewards with smoother drivability and better fuel economy—too easy.

Popular questions

Where is the MAP sensor on a 2011 Honda Odyssey?
It sits on top of the intake manifold near the throttle body, secured with two small bolts and sealed by an O-ring. There’s a single electrical connector—easy to spot and easy to reach with basic tools.

Does a 2011 Odyssey have a MAF sensor as well?
No. This model uses a speed-density setup. The ECU estimates airflow using the MAP sensor along with inputs like intake air temperature, engine speed and throttle position—no separate MAF sensor is fitted from factory.

Can a bad MAP sensor damage other parts?
It can. If the MAP reads incorrectly, the engine may run rich, which can overheat and poison the catalytic converters over time. Sorting MAP faults early helps protect the cats and keeps fuel consumption in check.
