Description |
Cause and reaction. |
| 11 |
Accelerator pedal sensor. |
Accelerator pedal sensor is defective or damaged wiring between the motor control unit and foot pedal. Incomplete pressing the accelerator pedal may have a sharp increase in engine speed. |
| 12 |
Idling speed switch pedal. |
Accelerator pedal sensor is defective or damaged wiring between the motor control unit and foot pedal. The accelerator pedal is not responding to pressing. |
| 13 |
Vehicle speed signal. |
Damaged wiring, faulty dash, faulty Tachograph. Cruise control does not work until the fault code is active. |
| 14 |
Power relay engine control unit. |
The relay is defective or damaged wiring. |
| 21 |
Internal malfunction of the engine control unit. |
Defective engine control unit. Cruise control does not work. |
| 22 |
A programming error in the engine control unit. |
Not programmed or programmed with a buggy engine control unit. Engine will not start. |
| 23 |
Coolant temperature sensor. |
The sensor may be faulty, damaged wiring, water pump works with incomplete effectiveness, crammed with honeycomb radiator or defective thermostat. |
| 24 |
Charge air temperature. |
The sensor may be faulty, damaged wiring, clogged honeycomb intercooler (an intercooler), mechanical failure of the engine. At temperatures above 91° air discharge with “Check Engine” lamp will light up continuously when the engine power will be reduced. In the event of a fault in the wiring harness or defective sensor “Check Engine” lamp will blink. |
| 25 |
Charge air pressure. |
The sensor may be faulty, damaged wiring, defective, damaged or clogged the turbocharger intercooler cooler, mechanical failure of the engine.Reduced engine power increased the toxicity of exhaust gases. |
| 26 |
Speed sensor camshaft. |
Faulty speed sensor camshaft, damaged wiring, broken synchronization between signals from speed sensor camshaft and crankshaft sensor. In case of violation of synchronization will be active codes 26 and 27 at the same time.Engine runs for a long time or may not start for the first time. |
| 27 |
Speed sensor the crankshaft. |
Faulty speed sensor, crankshaft damaged wiring, broken synchronization between signals from speed sensor camshaft and crankshaft sensor. In case of violation of synchronization will be active codes 26 and 27 at the same time.Engine runs for a long time or may not start for the first time. |
| 31 |
Pump-injector cylinder No. 1. |
Defective pump-injector, damaged wiring between the motor and the control unit pump-injector, mechanical failure in the engine. Engine is not exactly possible increased exhaust gas smokiness. |
| 32 |
Pump-injector cylinder No. 2. |
Defective pump-injector, damaged wiring between the motor and the control unit pump-injector, mechanical failure in the engine. Engine is not exactly possible increased exhaust gas smokiness. |
| 33 |
Pump-injector cylinder # 3. |
Defective pump-injector, damaged wiring between the motor and the control unit pump-injector, mechanical failure in the engine. Engine is not exactly possible increased exhaust gas smokiness. |
| 34 |
Pump-injector cylinder # 4. |
Defective pump-injector, damaged wiring between the motor and the control unit pump-injector, mechanical failure in the engine. Engine is not exactly possible increased exhaust gas smokiness. |
| 35 |
Pump-injector cylinder # 5. |
Defective pump-injector, damaged wiring between the motor and the control unit pump-injector, mechanical failure in the engine. Engine is not exactly possible increased exhaust gas smokiness. |
| 36 |
Pump-injector cylinder # 6. |
Defective pump-injector, damaged wiring between the motor and the control unit pump-injector, mechanical failure in the engine. Engine is not exactly possible increased exhaust gas smokiness. |
