1HD-FTE MAP Sensor Genuine 89421-20210 HDJ100 HDJ79

Genuine Toyota Mass Air Pressure Sensor from the 1HD-FTE engine found in the HDJ100 & HDJ79 LandCruiser.

The ECU uses this sensor to calculate fuel volume in correlation to boost pressure. A faulty sensor will often result in reduced performance, check engine lights or intermittent limp mode.

Located on the back of the crossover pipe from factory. Often relocated when the crossover is deleted. This sensor requires a stable boost reference to the intake manifold to function correctly.
