2011 Honda Accord MAP sensor — what it does and how to look after it

Technical sources confirm the 2011 Honda Accord is fitted with a Manifold Absolute Pressure (MAP) sensor. The Honda Factory Service Manual for the 2008–2012 Accord (K24Z 2.4‑litre and J35Z 3.5‑litre engines) specifies a MAP sensor mounted on the intake manifold, used by the PCM for load and fuelling calculations. Honda’s parts catalogue lists a MAP sensor for these engines, and Honda diagnostic procedures reference DTCs P0106, P0107 and P0108 for MAP circuit faults. On that basis, the MAP sensor is fitted and relevant to all 2011 Accord petrol variants.

On a 2011 Accord, the MAP sensor is the engine’s “ears” for manifold pressure. It continuously measures vacuum/pressure in the intake manifold and feeds that data to the PCM, which then calculates how much fuel to inject and where to set ignition timing. That’s why a healthy MAP sensor helps the Accord start cleanly, idle smoothly, use less fuel on the open road, and pass emissions without fuss.

There’s no set replacement interval for the MAP sensor, it’s a monitor-and-maintain item. During regular servicing, it pays to give it a quick once-over:

• Check the electrical connector for corrosion, loose terminals or broken locking tabs.
• Make sure the sensor’s O‑ring seals properly where it mounts to the manifold (the Accord’s sensor is direct‑mount, not hose‑fed).
• If there’s oil mist or carbon in the port, remove the sensor and gently clean the tip and port with electronics-safe cleaner. Avoid harsh solvents or poking tools inside the sensor.

Common signs the MAP sensor needs attention include rough idle, a flat spot on take-off, poor fuel economy, hard starting, sootier exhaust, or the check engine light with codes like P0106–P0108. If those pop up, a scan and live-data check of MAP kPa against barometric pressure and throttle position is the smart next step.

Replacement is straightforward under the bonnet: unplug the connector, remove the retaining fasteners, lift the sensor out, renew the O‑ring, and refit, tightening to the workshop manual spec. Clear any stored codes and take it for a drive to let the PCM relearn trims. Keeping the PCV system tidy and the throttle body clean will also help prevent contamination reaching the sensor, especially on higher‑kilometre Accords driven in stop‑start traffic.

Looked after this way, the MAP sensor will keep the 2011 Accord running sweet, from city commutes to long Kiwi and Aussie kilometres.

Popular questions about the 2011 Honda Accord MAP sensor

Where is the MAP sensor located on a 2011 Accord?
It’s mounted on the intake manifold, typically near the throttle body. It’s a small, rectangular sensor with a two‑bolt flange and an electrical plug. No vacuum hose—just a sealed port into the manifold via an O‑ring.

Can you drive with a faulty MAP sensor?
The car will usually run, but not happily. Expect higher fuel use, sluggish performance, and possible stalling or hard starts. Prolonged driving can harm the catalytic converter, so it’s best to diagnose and fix it promptly.

Does the 2011 Accord use a MAF as well as a MAP?
No. The 2011 Accord’s petrol engines use a speed‑density strategy based on MAP, intake air temperature, engine speed and throttle position—there’s no mass air flow sensor in this model range.
