Honda CR-V MAP Sensor Guide for 1997-2006 Models
Is your first or second-generation CR-V running rough, getting bad gas mileage, or stalling? Your MAP sensor might be the problem.
- A failing MAP sensor on a 1997-2006 CR-V commonly causes a rough idle, poor fuel economy, and a Check Engine Light with codes P0107 or P0108.
- Replacement is an extremely easy DIY job that takes less than 15 minutes with a Phillips screwdriver.
- For this vehicle, an affordable aftermarket replacement part is a reliable and smart choice over a more expensive OEM part.
- Always check the electrical connector and for vacuum leaks before assuming the sensor itself is bad.
Is Your CR-V Showing Signs of a Bad MAP Sensor?
When a MAP sensor starts to fail, it sends incorrect information to your CR-V's computer. This can cause a variety of noticeable engine problems. Because the sensor is vital for calculating the right air-fuel mixture, a bad one often makes the engine run poorly. You should get the issue checked soon to avoid causing damage to other parts, like your catalytic converter.
Key Symptoms of Failure:
🎬 Watch: Common symptoms of a failing MAP sensor explained- Check Engine Light: This is often the first sign. The most common trouble codes are P0107 (MAP Sensor Circuit Low Voltage) and P0108 (MAP Sensor Circuit High Voltage). 🎬 See how to diagnose and fix a P0108 trouble code
- Rough Idle: Your CR-V may shake, sputter, or have an unstable RPM at idle.
- Poor Fuel Economy: A bad sensor can cause the engine to run rich, burning more fuel than necessary.
- Lack of Power: The vehicle may feel sluggish, hesitate when you accelerate, or even stall.
- Failed Emissions Test: An incorrect air-fuel ratio will lead to higher emissions.
Check This First!
Before you replace the sensor, check the basics. Make sure the electrical connector is plugged in securely and is free of corrosion. Also, inspect the vacuum lines for any cracks or leaks, as a vacuum leak can cause the same symptoms as a bad sensor.
Choosing an Aftermarket MAP Sensor for Your CR-V
For a 1997-2006 CR-V, a new aftermarket MAP sensor is a very cost-effective solution. While some mechanics prefer to use only OEM parts on Hondas, a quality aftermarket sensor from a known brand will perform reliably in these vehicles. Given the low cost of the part and the simplicity of the replacement, an aftermarket sensor is a smart choice for a DIY repair. For this specific vehicle and part, the difference in performance between an affordable aftermarket part and a more expensive OEM one is minimal for most drivers.

Where is the MAP sensor located on my 1997-2006 CR-V?
The MAP sensor is located directly on top of the throttle body. It's a small, black plastic sensor held in place with two screws and has a single electrical connector attached.
Can I clean the MAP sensor instead of replacing it?
It is generally not recommended or effective to clean a MAP sensor. The sensing element is internal and not easily reached. If the sensor is faulty, replacement is the only reliable fix.
Are there any recalls for the MAP sensor on my CR-V?
No. A search of NHTSA records shows no specific recalls or widespread technical service bulletins (TSBs) for the MAP sensor on the 1997-2006 Honda CR-V. Failures are typically due to the vehicle's age and mileage.
What's the difference between a MAP and a MAF sensor?
Your 1997-2006 CR-V uses a MAP (Manifold Absolute Pressure) sensor to measure engine load based on pressure/vacuum. It does not have a MAF (Mass Air Flow) sensor, which measures the volume and density of air entering the engine. The two sensors perform a similar function but measure different things.
