General code faults Toyota

B126A

Failure or failure during operation of the switch unit of the remote control of the starter.

 

B279A

Communication failure or no signal between the ECM and the control unit. This error is usually associated with a battery discharge or surges.

 

B1608

K od 1608 is common for airbags. To solve the problem, a detailed inspection of pyrocartridges and sensors installed on the devices, as well as their wires, is required.

 

B1801

Damage to the electric circuit of the pyrocartridge of the airbag installed by the driver.

 

4134

This code is not described in the service documentation for vehicles with V10, SV30, 1UZ engines and other versions. This error on cars of 2011 and other years of release can appear when reading by the scanner which is not suitable for diagnostics. In practice, the formation of this code is associated with problems with the ABS system, but to obtain more accurate data, you should diagnose the car with the appropriate equipment.

 

A799

Code A799 is not in the official documentation for deciphering Toyota combinations. This is an error of the scanner, the operating parameters of which are not suitable for diagnostics. It is recommended that you use other equipment for testing.

 

P004B

Left turbine malfunction.

 

P004C

Turbocharger malfunctions. The reason may be low voltage on the power line. Diagnostics of the compressor device with the mechanical drive is required.

 

P004D

Malfunction of the solenoid of the turbocharger.

 

P011B

The parameters for measuring the inlet air temperature or coolant temperature are outside the permissible limits. Obtaining control units values are random. The user needs to check the operation of the sensors of these two systems.

 

P0017

Problems related to the correlation of controller B. The cause of the fault may be the incorrect position of the crankshaft and camshaft.

 

P0093

Code P0093 on diesel and gasoline engine indicates a serious leak of fuel from the fuel system. The cause of the problem may be damage to the tank or the destruction of the component of the plunger of the high-pressure fuel filter. It is also recommended to diagnose the injectors.

 

P0441

Error P0441 occurs as a result of poor purge of the fuel vapor trapping system.

 

P0442

Fixation of fuel leakage by the control unit. It is necessary to check all places of connections of fuel system, integrity of a tank.

 

P0446

Malfunction of the fuel evaporation and purge control system. The emission sensor may have failed, but the car owner should first make sure that all highways are intact. The problem may be caused by damage to the controller power line.

P0456

Code P0456 is also associated with fuel vapor leakage.

 

P0741

Error P0741 indicates incorrect clutch adjustment.

 

P0773

On Toyota Ace 3Y, A FE and other versions with a "robot" gearbox, this code appears due to a malfunction of the solenoid E. In practice, this problem is usually associated with a break or short circuit in the winding installed directly in the device. If cleaning the contacts and chips did not help, you will need to disassemble the transmission unit and diagnose with the replacement of the solenoids themselves.

 

P0820

On cars of 2004 and other years of release this combination is formed at failure of the switch of a neutral transfer.

 

P1238

Code P1238 (1238) is related to a malfunction in the secondary circuit of the fuel pump. It is necessary to diagnose the pump device and make sure that the filter works.

 

P1248

On Toyota Vista 3S, Prius 20 and other versions, this code indicates that the power unit is switched off or its power is limited. The occurrence of the error is due to malfunctions of the exhaust gas recirculation flow module.

 

P1262

Literally , this code is deciphered as "reduced circuit of the second turbocharger control sensor". It is necessary to check up work of the controller, and also to be convinced of integrity of all branch pipes of system.

 

P1601

The microprocessor module detects that the ECM module is too high.

 

P1602

The control unit sent a message stating that the car's battery power is 0%. The battery needs to be checked and charged.

 

P1635

On cars of 1991 and other years of release this code appears at a condition of an incorrect ratio of tires and axles. Operating parameters are outside the range of permissible characteristics.

 

P2002

Clogged soot filter.

 

P2463

Diesel soot filter clogging. Possible failures in the operation of the power unit - arbitrary stop, lack of power, failures when pressing the gas. You need to check the quality of the filter element and replace it if necessary.

 

P2646

Stuck in the off state or incorrect operation of the valve actuator control system.

 

C120A

The C120A combination reports incorrect settings of the electronic control unit. A possible cause of the error may be the use of an outdated version of the module software.

 

C1207

Failure or incorrect operation of the starter mechanism module. If this problem occurs, the engine may have difficulty starting.

 

C1208

Code C1208 On Toyota Carina 4A FE and other models indicates incorrect steering position. If the appropriate steering wheel sensor has recently been replaced, it is likely that it has not been calibrated. You should also make sure that the loop to which the controller is connected is intact.

 

C1515

No adjustment or calibration of the engine torque control has been performed.

 

C1223

The C1223 combination is a common ABS system. There are many possible reasons for this code, from sensors to a faulty control module.

 

C1238

The microprocessor module reports the ingress of foreign particles between the rotor mechanism and the speed controller of the rear left wheel. To solve the problem, clean the plug and check the integrity of the contact elements.

 

C1242

General malfunction of ABS and VSC systems. The user needs to check all control modules of these nodes, as well as the quality of contacts with sensors.

 

C1377

Literally the error is translated into Russian as " capacitor". The problem may be in the capacitor element mounted on the board of the microprocessor module or one of the control units.

 

C1401

General malfunction of the anti-slip system module.

 

C1441

Literally code C1441 translates as "reduced performance of the braking function". The cause of the problem may be problems with the stability system. Probably a fault should be found in the amplifier.

 

C1452

The combination C1452 indicates a reduced pressure in the accumulator. A detailed check of the device and the integrity of the hoses connected to it is required.

 

C1542

Internal malfunction of the anti-slip system.

The following components are subject to diagnosis:

• all sensors mounted on wheels;
• anti-slip control unit;
• wires from the ABS control module to the controllers and the control unit;
• contacts on regulators.

 

C2540

This code means that the power of the hybrid system is reduced. This error cannot appear on the injectors. The fault is investigative, so it is necessary to test the car in detail.
