This Speed Sensor A/T is a genuine OEM replacement for Isuzu NPR, Isuzu NPR-HD, Isuzu NQR, and Isuzu NRR manufactured from 1995 through 2016 with the 4HK1 5.2 L diesel engine.

The automatic transmission (A/T) speed sensor measures the rotational speed of the transmission output shaft and sends this data to the engine control module (ECM) or transmission control module (TCM). Proper function of the speed sensor is essential for the following:

• Accurate speedometer readings

• Smooth gear shifts and transmission performance

• Engine and transmission efficiency

• Prevention of erratic shifting or torque converter issues

A failing speed sensor may cause the following:

• Inaccurate or non-functional speedometer

• Harsh or delayed automatic transmission shifts

• Transmission warning lights or error codes

• Poor fuel economy

• Limp mode in some models

Installing a new OEM speed sensor restores accurate readings and ensures reliable automatic transmission operation.
