DTC | M.U.T.-III SE screen terms (Trouble diagnosis content) | DTC detection condition | ||
P0191 | 00 | FRP SENSOR A (Fuel rail pressure sensor “A” circuit range/performance) | Diagnosis condition | Ignition switch ON |
Signal (terminal) | Fuel rail pressure sensor signal | |||
Threshold | Fuel rail pressure remains at more than 14.5 MPa (147.9 kg/cm2, 21025 psi) | |||
Diagnosis delay time | 0.2 seconds or more |
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.
| ||
Combustion control mode | Stratified charge combustion control at starting | No stratified charge combustion at starting (cold start). |
note | Warm up the engine until “COOLANT TEMP/S” in “DATA MONITOR” mode in “ENGINE” of M.U.T.-III SE reaches at least 70°C (158°F). |
