Honda Accord Manifold Absolute Pressure (MAP) Sensor Guide: 2006-2018
Everything you need to know about diagnosing and replacing the MAP sensor on your 2006 to 2018 Honda Accord.
- A bad MAP sensor will almost always trigger a Check Engine Light with codes P0107 or P0108.
- For an OEM-quality replacement, choose the Denso brand, as they are an original supplier for Honda.
- Replacement is a very simple, 15-minute DIY job with basic tools, saving you over $100 in labor.
- Do not ignore symptoms; a faulty MAP sensor can lead to poor fuel economy, failed emissions tests, and potential damage to the catalytic converter.
Is Your Honda Accord's MAP Sensor Failing?
A failing Manifold Absolute Pressure (MAP) sensor can cause noticeable problems with your Accord's performance. Because the sensor's data is so important for the air-fuel mixture, a bad reading can make the engine run too rich (too much fuel) or too lean (not enough fuel). This can lead to a range of issues from annoying to serious.
Key Symptoms of a Bad MAP Sensor:
- Check Engine Light: This is often the first sign. The sensor will trigger specific trouble codes, most commonly P0107 or P0108. 🎬 Watch: How to test and replace a sensor with these codes.
- Poor Fuel Economy: If the computer thinks the engine is under more load than it is, it will inject extra fuel, causing you to visit the gas station more often.
- Rough Idle: The engine may vibrate, shudder, or sound unstable when you're stopped. In some cases, it might even stall.
- Hesitation or Lack of Power: When you press the gas pedal, the car might feel sluggish or struggle to accelerate.
- Black Smoke from Exhaust: This is a sign of a rich fuel mixture, where unburned fuel is exiting through the exhaust.
- Failed Emissions Test: An incorrect air-fuel ratio will lead to higher emissions, causing a failure on a smog test.
Known Issues, Recalls, and TSBs
For the 2006-2018 Honda Accord, there are no widespread safety recalls or Technical Service Bulletins (TSBs) issued specifically for the Manifold Absolute Pressure sensor. While other recalls exist for this vehicle range, the MAP sensor has proven to be a generally reliable component.
Choosing the Right Aftermarket MAP Sensor
When replacing the MAP sensor on your Accord, you have a choice between OEM and aftermarket parts. For many Honda parts, the original manufacturer is often the best choice, but for the MAP sensor, you can get OEM quality from a specific aftermarket brand.
- Top Tier (OEM Supplier): Denso is a well-known original equipment manufacturer for Honda. Choosing a Denso MAP sensor is the closest you can get to buying the part from a Honda dealership, often at a better price. It is designed to meet the exact specifications for your Accord's engine.
- Reliable Aftermarket Tier: Brands like NGK, Delphi, and Standard Ignition (SMP) are reputable manufacturers that produce quality sensors. They are generally reliable and offer a good balance of price and performance. However, always double-check the fitment for your specific year and engine, as one user reported an issue with a Standard part on a newer 1.5T engine, which is outside this guide's year range.
- Economy Tier: Other brands like Walker Products, Global Parts, and Holstein offer more budget-friendly options. These can be a good value, but may not have the same long-term durability or precise calibration as the top-tier brands.
MAP Sensor Replacement Cost for 2006-2018 Honda Accord

Frequently Asked Questions
Where is the MAP sensor located on a 2006-2018 Honda Accord?
The MAP sensor is very easy to find. It is mounted directly on the engine's intake manifold, usually near the throttle body. On most 4-cylinder and V6 models in this year range, it is held in place by one or two small bolts (either an 8mm hex head or a Phillips head screw).
Can I clean the MAP sensor instead of replacing it?
Sometimes, cleaning the sensor can resolve issues, especially if it's contaminated with carbon or oil. You can use a dedicated Mass Airflow or electronics cleaner. 🎬 See this easy guide on how to clean your MAP sensor. However, if the sensor's internal electronics have failed, cleaning will not help and replacement is the only solution. Given the low cost of a new part, replacement is often the more reliable fix.
What are the common trouble codes for a bad MAP sensor?
The two most common codes are P0107 (Manifold Absolute Pressure Sensor Circuit Low Voltage) and P0108 (Manifold Absolute Pressure Sensor Circuit High Voltage). P0107 means the computer is seeing a voltage signal that is too low, while P0108 means the signal is too high. Both point to a problem with the sensor or its circuit.
Is replacing the MAP sensor a difficult DIY job?
No, this is one of the easiest DIY jobs you can do. The sensor is easily accessible and only requires basic hand tools like a screwdriver or a small socket wrench. The entire process of disconnecting the electrical plug, removing the bolt(s), swapping the sensor, and re-installing takes less than 15 minutes for most people.
