Locate the map sensor along the firewall or to the passenger side of the engine compartment. 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. An overly rich or lean mixture caused by faulty data from the map sensor will make starting difficult.

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). A bad map sensor sending the wrong signal to the computer can disrupt fuel consumption and overall engine performance.

I tested the map sensor with a vac pump and it does respond to vacuum. Or, better be proactive by inspecting your map sensor during routine maintenance checkups.you can use a scan tool for this (your map sensor reading at idle should have a reference voltage close to five volts) and administer a bench test using a hand vacuum pump.

If ok, replace the map sensor. Testing a digital map sensor. Output voltages between 0.5 and 1.5 volts indicate a high vacuum (low pressure) situation, such as idle or deceleration.

It Preceded The Mass Airflow Sensor And Was Much Less Efficient.

Spit on debatethe main thing is to do the work, not talk about itwe know and respect our customers!and dirty work is included. Test the map sensor supply voltage between the sensor connector terminals a and b (2.4l, 3.3l and 3.8l engines) r a and c (3.0l engine) with the ignition key in the on position. Pays for itself many times over and get to know your bike better as well as knowing the job is done correctly.
