Key Specificatiom 

Isuzu engine boost pressure sensor 1802200140 it measures turbocharger boost pressure in the intake manifold and transmits a proportional voltage signal to the engine ECM, which uses this feedback for precise fuel delivery and boost control. The sensor is fitted to a wide range of Isuzu engines and is commonly found on Hitachi excavators ZX200-3 ZX240-3 ZX330-3 ZX350-3 ZX450-3, CASE excavator CX330 CX210B CX370B CX460, JCB excavator JS200 JS220, John Deere excavators, Doosan excavators. It is a direct-fit replacement for the OEM part. Related numbers Densor 079800-5550, 180220-0140, Hitachi number 4657944, Case number 87379342, JCB number 716/30309

Maintenance and Repair

The ECM reports boost sensor circuit faults using the following error codes (Isuzu 4HK1 6HK1 platform):

• P0237 Boost Sensor Circuit Low Voltage Open circuit, short to ground, or signal below valid threshold
• P0238 Boost Sensor Circuit High Voltage Short to power supply, ground circuit open, or signal above valid threshold
• P0234 Turbocharger over-boost Boost pressure exceeds commanded limit (may be secondary to sensor signal corruption)
• P0299 Turbocharger under-boost Boost pressure below expected; can be caused by a biased/failed sensor or actual boost leak.
