P1140: VGT3 (warning lamp flashes: 53)
P1142: VGT3 (warning lamp flashes: 53)
P1143: VGT3 (warning lamp flashes: 53)
Generation condition
Current flowing in the turbocharger magnetic valve (No. 3 magnetic valve) re-
mains above the specified value for 1 second.
Recoverability
System recovers when current flowing in the turbocharger magnetic valve (No.
3 magnetic valve) becomes normal for 1 second.
Control effected by electronic control unit
• Turbocharger control is stopped.
• Exhaust gas recirculation control is stopped.
• Auto cruise control is stopped.
• Injection quantity is limited. (Output is reduced, and exhaust emissions wors-
en.)
• Actuator test “BA: VGT Test” is stopped.
Inspection
Service data 21: VGT position, 84: VGT M/V3
Actuator test AB: VGT3

Electric circuit diagram Turbocharger magnetic valve (No. 3 magnetic valve) system
Generation condition
Turbocharger magnetic valve (No. 3 magnetic valve) circuit shorted to ground
or open-circuited (low level when turned OFF) as detected for 1 second.
Recoverability
System recovers when current flowing in the turbocharger magnetic valve (No.
3 magnetic valve) becomes normal (high level when turned OFF) for 1 second.
