P0192: CRS Pressure SNSR (Low) (warning lamp flashes: 11)
Generation condition
Accelerator pedal position sensor 1 voltage remains higher than 4.5 V for 1 sec-
ond.
Recoverability
System recovers when accelerator pedal position sensor 1 voltage remains 4.5 V
or less for 1 second.
Control effected by electronic control unit
•
If accelerator pedal position sensor 1 alone is faulty
Control is effected using accelerator pedal position sensor 2.
•
If both accelerator pedal position sensors 1 and 2 are faulty
•
Exhaust gas recirculation control is stopped.
•
Auto cruise control is stopped.
•
Turbocharger control is stopped.
•
Control is effected using backup value (when accelerator pedal switch is
ON: accelerator pedal is not pressed (0%); when the switch is OFF: the
pedal is pressed 30%).

Recoverability
System recovers (power is re-supplied to electronic control unit) if signal becomes
normal when starter switch is turned OFF (2 minutes or more)
→
ON.
Control effected by electronic control unit
•
Common rail pressure open loop control is effected.
(Output is reduced, and exhaust emissions worsen.)
•
Exhaust gas recirculation control is stopped.
•
Auto cruise control is stopped.
•
Actuator tests “B9: Fuel Leak Check, BB to C0: Injector Test, BA: VGT Test”
are stopped.
