DTC Description

DTC DETECTION LOGIC

DTC		M.U.T.-III SE screen terms (Trouble diagnosis content)	DTC detection condition
P0192	00	FRP SEN/CIRC (Fuel Rail Pressure Sensor Circuit Low Bank 1)	Diagnosis condition	Engine running at idle
			Signal (terminal)	Fuel rail pressure sensor signal
			Threshold	Signal voltage from the fuel rail pressure sensor remains at less than 0.14V
			Diagnosis delay time	5 seconds or more

POSSIBLE CAUSE

Harness or connectors (Fuel rail pressure sensor circuit is open or shorted.)
Fuel rail pressure sensor

FAIL-SAFE

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Traveling control mode

Accelerator angle variation control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.

note	ECM does not control the accelerator pedal releasing speed.

Combustion control mode

Stratified charge combustion control at starting

No stratified charge combustion at starting (cold start).
