2015 Honda Accord MAP sensor: what it does and how to look after it

Technical sources confirm the 2015 Honda Accord is fitted with a MAP (Manifold Absolute Pressure) sensor. The Honda Accord 2013–2015 workshop manual (Fuel and Emissions – MAP Sensor inspection/replacement), the Honda electronic parts catalogue (listing a “Sensor Assy., MAP” on the intake manifold for both 2.4‑litre K24W and 3.5‑litre J35Y engines), and common OBD‑II references (DTCs P0106–P0108 for MAP performance/range) all document its presence. Major aftermarket catalogues from Denso and NGK/NTK also list a MAP sensor for this model year.

The MAP sensor on a 2015 Honda Accord measures the absolute pressure inside the intake manifold, letting the engine computer figure out real‑time engine load. That data helps trim fuel delivery, set ignition timing, and manage systems like EGR and evap for smooth drivability, strong economy, and low emissions. On these Accords, the MAP works alongside the air‑mass and throttle inputs, and it’s especially handy for quick throttle changes and altitude compensation when the car’s driven across New Zealand’s ranges or Australia’s high country.

While not a scheduled service item, the MAP sensor benefits from a quick check during routine servicing. A healthy sensor helps keep fuel use and emissions in check, and prevents that doughy throttle feel. Tell‑tale signs of a dodgy MAP include rough idle, flat spots on take‑off, higher than usual litres‑per‑100 km, and the check engine light with faults like P0106, P0107, or P0108.

• Inspect the sensor’s connector and wiring under the bonnet for corrosion, rub‑through, or moisture.
• Make sure the O‑ring seals properly and the mounting area on the manifold is clean.
• If contamination is visible at the port, a light mist of electronics‑safe cleaner can clear deposits—avoid soaking or poking the sensing element.
• Check for vacuum leaks around the manifold and throttle body, a “good” MAP can read wrong if there’s unmetered air.

Replacement is straightforward: disconnect the battery, unplug the connector, undo the fastener, lift the sensor and O‑ring, and refit the new unit. Use an OE‑quality part, seat the O‑ring squarely, and nip the fastener to spec. After refitting, an idle relearn helps, a scan tool should show key‑on/engine‑off readings close to local barometric pressure (about 100 kPa at sea level) and sensible manifold vacuum at idle. For owners clocking big kilometres or doing dusty outback or rural NZ driving, pairing MAP checks with air‑filter and throttle‑body maintenance keeps the Accord happy and frugal.

Does a 2015 Honda Accord have a MAP sensor or a MAF?

It has a MAP sensor, and models in this year range also use a MAF. The ECU blends signals from both to calculate load accurately, sharpen throttle response, and fine‑tune fuel economy and emissions.

Where is the MAP sensor on a 2015 Accord?

It’s mounted on the intake manifold near the throttle body, secured with a small fastener and sealed by an O‑ring. There’s a single electrical plug. On the V6, it sits on the upper plenum, on the 4‑cylinder, it’s on the main manifold casting within easy reach from the top of the engine bay.

Can a failing MAP sensor be cleaned, or should it be replaced?

Light cleaning of the port with electronics‑safe cleaner can help if there’s minor contamination. If the sensor throws repeated P0106–P0108 codes, shows implausible readings on a scan tool, or drivability stays poor after checks for air leaks and wiring faults, replacement with an OE‑quality unit is the smart move.
