What does the MAP sensor do on a Harley?

Manifold Absolute Pressure or MAP sensors are a major component on fuel injected and later carbureted Harley motorcycles. MAP sensors are used on most modern engines to monitor manifold pressure (vacuum), sending that information back to the electronic control module (ECM).

Is there a problem with the MAP sensor on a Harley?

On a fuel injected Harley if you suddenly need to add throttle to start the engine, this is a common sign of a failing MAP sensor. Check Engine Light or trouble code.

Can a bad MAP sensor cause engine failure?

MAP sensor on footwell inside engine compartment. A bad manifold absolute pressure (MAP) sensor can upset fuel delivery and ignition timing. Depending on your vehicle model, your engine might experience one or more of these performance problems: However, these symptoms are not exclusively symptoms of a failed MAP sensor.

What does a check engine light on a MAP sensor mean?

A check engine light will appear if the sensor fails or if certain trouble codes have been recorded based on different malfunctions. Trouble codes may not always be recorded by all intermittent failures. It is also important to check the orange seal that mates the MAP sensor to the intake manifold.

Why does my Harley Davidson have an O2 sensor issue?

The o2 code is probably due to the over rich condition. I think you need a REAL tuner (person, not device) to get a hold of it. The engine codes are the typical ones…you know. p0131 and p0151 and then it gave me something I can’t quite figure what the code is to 34562-07. It looks like a part number but I could be wrong.

On a fuel injected Harley if you suddenly need to add throttle to start the engine, this is a common sign of a failing MAP sensor. Check Engine Light or trouble code.

What are the symptoms of a failing MAP sensor?

Common symptoms of a failing manifold absolute pressure sensor (MAP) include rough idle, poor gas mileage, hard starts, stalling, or a check engine light (trouble code recorded). Check your service manual or verify with a trained technician to further diagnose and determine the cause of such problems.*
