High map sensor reading
WebThe load value is computed using inputs from the MAP sensor, TPS sensor, airflow sensor and engine speed. The value should be low at idle, and high when the engine is under load. No change in the value, or a higher than normal reading at idle might indicate a problem with the MAP sensor, TPS sensor or airflow sensor. WebApr 13, 2015 · The reason your MAP readout dropped when you increased throttle in neutral is that the engine speed increased. Manifold pressure doesn't just depend on throttle, but also on engine speed (pressure drop is roughly proportional to density times the square of the flow velocity, at a given throttle opening).
