P0193: CRS Pressure SNSR (High) (warning lamp flashes: 11)
P0200: Injector Circuit 1 (warning lamp flashes: 82)
P0201: Injector M/V-Cylinder 1 (Load) (warning lamp flashes: 37)
Generation condition Common rail pressure sensor voltage remains higher than 4.8 V for 0.25 second.
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.
Inspection
Service data 0C: Difference Common Rail Pressure
Electrical equipment #319: Common rail pressure sensor
Electric circuit diagram Common rail pressure sensor system
Generation condition
Injector circuit (No. 1, 2 or 3 cylinder) is short-circuited, open-circuited, or over-
loaded.
Recoverability
System recovers (power is re-supplied to electronic control unit) if signal be-
comes normal when starter switch is turned OFF (2 minutes or more) → ON.
Control effected by electronic control unit
• Injector magnetic valve (No. 1, 2 or 3 cylinder) control is stopped. (Output is
reduced due to three-cylinder operation, and exhaust emissions worsen.)
• Exhaust gas recirculation control is stopped.
• Auto cruise control is stopped.
• Turbocharger control is stopped.
• Actuator tests “B9: Fuel Leak Check, BB to C0: Injector Test, BA: VGT Test”
are stopped.

Electric circuit diagram Injector magnetic valve (No. 1, 2 or 3 cylinder) system
Generation condition
Injector magnetic valve (No. 1 cylinder) is short-circuited, open-circuited or over-
loaded.
Recoverability
• When short-circuited or overloaded
• 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.
• When open-circuited
• System recovers if signal becomes normal with starter switch in ON posi-
tion.
Control effected by electronic control unit
• Exhaust gas recirculation control is stopped.
• Injector magnetic valves (No. 1, 2 and 3 cylinder) are stopped.
(Output is reduced, and exhaust emissions worsen.)
• Auto cruise control is stopped.
• Actuator test “BA: VGT Test” is stopped.
