Overview — General Parts MAP 8093732691
8093732691 is the MAP (manifold absolute pressure) sensor used on HITACHI machines to measure intake manifold pressure and feed the signal to the engine control system. We can supply this sensor as well as the related family numbers listed below, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The sensor is built to the original electrical specification, with the pressure port, connector layout and signal output matched to the HITACHI engine harness. The housing is sealed against moisture and vibration, and the terminal pins are gold or tin plated for a stable connection. As an OEM-spec sensor, it plugs straight into the original connector and delivers the same voltage curve the ECM expects, without adapters or recalibration.
Applicable Models & Applications
This MAP sensor is used on HITACHI excavators and related machines where intake manifold pressure is monitored for air-fuel ratio and load control. The family references 8281397750 and 8972177780 cover the same sensing duty on adjacent engine builds. Typical positions include the intake manifold, charge air cooler outlet and intake piping on turbocharged engines. Confirm the connector style, pressure range and mounting position against the sensor removed from your machine before ordering.
Maintenance & Replacement
A failing MAP sensor shows up as poor starting, rough idle, black smoke, loss of power and fuel-economy complaints, often with a related fault code. Inspect the sensor and its connector periodically, looking for oil contamination, cracked housing and corroded pins. When replacing, clean the manifold port, fit the sensor with a new O-ring, and torque it to specification. Verify the harness connector locks fully and that the wiring is routed away from heat sources.
Price Reference (USD)
The reference price for this General Parts MAP sensor (8093732691) is approximately USD 30 – 150 per unit depending on grade, quantity and shipping destination. This is a planning estimate only — confirm current pricing and availability with our sales team before ordering.

Value & Service
An incorrect pressure sensor can trigger fault codes and poor running, so we verify 8093732691 against the original HITACHI connector and pressure range before dispatch. We stock the sensor and the family numbers above, and they can ship together with the intake gasket and filter service kit in one tracked order. Our team will confirm the correct sensor for your machine’s engine control system before you buy.
