42 Invalid signal from speed controller. The cause of the problem may be the speedometer.
43 Lack of a starting pulse arriving on the block of management of the motor
44 Faulty output speed or rotation speed controller
45 General error in the operation of the control unit, indicating an incorrect signal from the device. It is necessary to check all the loops and pads connected to the module.
46 Malfunctions in the fourth solenoid or damage to its wiring
47 Failure of the additional throttle control. A possible cause may be damage to the power cable or oxidation of the connector.
48 Malfunctions in the operation of the additional air supply control system
49 Break or damage to the power line supplying the stop lamp switch
51 No idle speed from TPS
52 Lack of impulse from knock controller. If the car is equipped with two appropriate sensors, then the problem should be sought in one of them.
53 The ignition timing is detected by the control unit. The user needs to check the integrity of the electrical circuits of the knock sensors.
55 Invalid signal from detonation controller
59 Incorrect ratio of crankshaft and camshafts, sensors need to be diagnosed
61 Failure in the operation of the main speed controller or damage to its power cable
62 Malfunction of the first solenoid valve or open circuit
63 Failure of the second solenoid valve or circuit damage
64 Malfunction of the third solenoid valve or open circuit.
65 Failure of the fourth solenoid valve or circuit damage
67 O / D activation controller malfunction or power line malfunction
71 Malfunctions in the operation of the EGR control system (EGR)
72 Faulty fuel cut-off sensor
74 Malfunction of the anti-skid system, an error reports the failure of one of the sensors. The user needs to check all the controllers mounted on the wheels.
77 Malfunction of the solenoid pressure control device in the automatic transmission. It is required to check the sensor and the integrity of its wiring.
78 Failure of the fuel pump or lack of signal from the device
81 Damage to the electrical circuit between the TCM and ECT1 modules
82 Open wiring between TCM and ESA1
84 Damage to the electrical circuit between the TCM and ESA2 modules
85 Open circuit between TCM and ESA3
86 Failure of the engine speed controllers
88 Damage to the electrical circuit going from the microprocessor module to the control unit of the transmission unit. This refers to an automatic transmission.
89 Lack of communication between the microprocessor-based motor control module and the TRC VSR system unit
93 Gaps in the operation of the ignition system
96 Failure or errors in the operation of the speed sensor
99 There are no combinations of errors in the vehicle.
TOYOTA Type 10 1 & 2-digit codes
1 Code that appears when there is no malfunction in the control unit or other vehicle systems
2 Invalid pulse, out of range, coming from the air mass meter
3 Invalid signal from communicator
4 The control unit detects a signal about the temperature of the refrigerant, which is outside the permissible limits. Possible damage to the sensor or damage to its wiring.
5 Lack of signal with oxygen controller
6 Incorrect engine idle, possible sensor malfunction
7 The control unit has detected that the throttle valve is in the wrong position. Perhaps the element is jammed.
8 Temperature controller shows incorrect intake air data
9 Incorrect vehicle speed readings
10 The control unit does not receive a signal about the activation of the starter mechanism. A possible reason may be the failure of one of the components of the ignition system:
- candles;
- coils;
- high voltage wires;
- distributor.
11 Air conditioning or climate control malfunction. There may be malfunctions in the operation of the toggle switch, which is responsible for switching modes.
