Mercedes Benz S300, N49 steering angle sensor zero deviation fault code can t be cleared what s goin

Mercedes-Benz S300, N49 steering angle sensor: Zero deviation The fault code cannot be cleared because there are some problems with the encoder, and there are also problems on the line. Replace the encoder or check the wiring.

A steering angle sensor is a device used to determine the angular position of an axis, such as a steering column, which comprises a coil group, a coil support and a coupler element that has a coupler angular position related to the angular position of the shaft. The coil group comprises a transmitter coil and at least one receiver coil, and the coupler element alters the inductive coupling between the transmitter coil and at least one receiver coil. The signal processing circuit receives a coil signal and a reference signal from the coil group and determines the angular position using the receiver signal and the reference signal, which is related to the axial displacement but is otherwise essentially independent of the angular position.

Its functions are as follows:

1. The direction of rotation of the steering wheel.

2. The steering wheel rotation angle.

3. The speed of steering wheel rotation.

Both ESP and EPS need this sensor for EPS to be aware of this signal, and can adjust the power assist effect with the speed (depending on the angle of the steering wheel and the speed of the steering wheel).

1) The larger the angle, the greater the resistance between the tire and the ground, and the need for power to increase.

2) The faster the rotation speed, the more urgent the situation, and the need to increase the power assist.

Mercedes-Benz ML350 164 reported N49 fault.

Learn, Mercedes ML, sensor, steering wheel.

When the vehicle comes, the ESP fault light is on, and the direction clearance is a little too large when the car hits the steering wheel, and the detection fault is the N49 steering sensor fault, and the steering column control module can display the value correctly when the steering wheel angle signal hits the direction, and the zero deviation value is too large to learn the next Delete the fault road test in a stop left and right when the direction is on, and the ESP light is on again when the factory is back to detect or N49 fault, so the N49 is ordered to be replaced, and the zero deviation is learned and troubleshooting is carried out after the replacement.

The steering angle sensor is a device for determining the angular position of the shaft, such as a steering column, which comprises a coil group, a coil support and a coupler element, and the coupler element has a coupling coincidental large coder angular position related to the angular position of the shaft;

The coil group comprises a transmitter coil and at least one receiver coil, and the coupler element changes the inductive coupling between the transmitter coil and at least one receiver coil. The signal processing circuit receives a coil signal and a reference signal from the coil group and determines the angular position using the receiver signal and the reference signal, which is related to the axial displacement but is otherwise essentially independent of the angular position.

Its functions are as follows:

Now the air conditioner is not cool.

This fault is a compressor failure, it is recommended that you check whether the air conditioner and the wiring are normal.

This fault is a compressor failure, it is recommended that you check whether the air conditioner and the wiring are normal.

The high pressure is at 8 pressures, and the low pressure is at 8 pressures.

If it is not cool, it is because the compressor is used to compress and deliver cold air, and the refrigerant can be checked for leaks.

When the owner came to change the water tank, the result was to dismantle the water tank with the heat dissipation network, and it was cool after installing it back, and it was not cold after a day.

The refrigerant is sufficient.

Yes, oh dear, that's a faulty compressor or a lack of refrigerant.

That's enough, it's a compressor failure.

A C button is required to turn on the null, and the A C button is the switch that adjusts the compressor. If the compressor is not working, the air naturally does not cool.

It is recommended to repair or replace the compressor.

Just opened a good air conditioner but the front air conditioner is not cold, at this time to see the pressure of the cold pump high and low pressure are normal, now start the engine again even the rear air conditioner guess is gone, please ask the data of the air conditioner is next to the sail will be lost.

Whether a match is required.

Pro, this re-do the initialization operation matching, on the line, the diagnostic computer selects the boot function into the air conditioning system to do it, and the options are directly corresponding.

Hello dear! 1, the engine electronic control unit does not receive the speed signal or the received signal is unstable, the possible reasons are: (1) the distance between the sensor potato taker and the target wheel is too large; (2) Short circuit or open circuit of the sensor wire; (3) The sensor is damaged.

2. Solution, measure the resistance between the two pins of the sensor, and this resistance value should be between: (1) If it exceeds the specified resistance range, it means that the sensor has been damaged, and the speed sensor should be replaced; (2) If the resistance value is within the specified range, we should continue to check whether the wire between the sensor and the engine electronic control unit has a short circuit to the ground, a short circuit to the positive electrode, an open circuit or a short circuit between the wires, and repair the problems found in time. If the problem is not resolved after the line fault has been ruled out for pre-ignition, the speed sensor should be replaced.

Summary. Hello dear and thank you for waiting. The 12 Mercedes-Benz S300 fault code 0524 indicates that the intake pipe pushes the damper sensor fault, which is the failure of the variable veneer of the intake manifold, which is mainly due to two reasons.

The first aspect needs to be considered is that the flap motor is faulty, and the second aspect needs to be considered that there is a problem with the sensor circuit of the flap motor. Like this fault**, you can first check whether the corresponding sensor wiring is normal, if there is no problem with the wiring, it is recommended that you consider replacing the intake manifold assembly. <>
