Frequently Asked Questions
What does P0192 mean on a Hino?
P0192 means Fuel Rail Pressure Sensor Circuit Low. The fuel rail pressure sensor signal is below its normal range, which usually points to a short to ground or a failed sensor.
Is P0192 a Hino-specific code?
No. P0192 is a generic OBD-II code defined by SAE J2012, so it means the same thing on any vehicle that sets it. The exact conditions Hino uses to set it on its diesels are in Hino service information.

How Do You Diagnose HINO-P0192?
Inspect the fuel rail pressure sensor connector and harness.
Check the fuel rail pressure sensor reference voltage, ground and signal against the service specification.
Check for other codes that share the same sensor reference voltage or ground.
