Where is the hall sensor - LG WM2101HW 4.0 cu.ft. Washer

- Loss of +15 volts power supply for Hall Effect Sensors. If power lose occurs when hall effect sensors are connected replace hall effect sensors. Confirm the voltage on the power interface board between pin 2 and the board common P16 with the hall effect sensor disconnected. If the voltage is not present replace the board.

Hall sensor function
A hall effect sensor is a sensor that produces a square wave output that can be directly read and modulated by the ECM (as opposed to an AC wave sensor which produces a sine wave that must be converted). They are used as cam position sensors and ABS wheel speed sensors.
Hall Effect Sensor and How Magnets Make It Works

No ,the box is probably not bad , but you need to have it programmed . The dealer is the only one that can do that ? The keys don't matter .
The passlock sensor mounted to the ignition switch assembly is located inside the upper right side of the steering column. The passlock sensor contains two hall effect sensors: a tamper hall effect sensor and a security hall effect sensor. The tamper hall effect sensor is mounted on top of the security hall effect sensor. Should someone attempt to defeat the system by use of magnetic experimentation, the tamper hall effect sensor will activate first.
The passlock system is a vehicle theft deterrent system which deters drive-away vehicle theft by disabling engine operation if the ignition lock cylinder is not rotated with the proper mechanically cut key.
The passlock system is made up of an ignition switch assembly, passlock sensor, body control module (BCM), instrument panel cluster (IPC), and a powertrain control module (PCM).
The ignition switch contains a magnet mounted on the lock cylinder and a passlock sensor assembly which consists of security hall effect sensor, tamper hall effect sensor, and output resistors. A drill proof metal shield is also staked over the sensor housing.

The BCM has the passlock controller integrated into it which controls the majority of the security systems logic. The BCM reads the data from the passlock sensor continuously. If the data is correct and has been received by the BCM within a specified time, the BCM will send a coded password to the PCM. The PCM will then allow the fuel injectors to operate.
The coded password for the security system is sent from the body control module to the PCM via the class 2 data link. If the password is correct and received within the specified time, the PCM will allow the fuel injectors to operate.
Sorry but you can't just replace parts , you need to know how the system works . You need to take this to a ASE certified repair facility that knows how it works .

motor capacator

I am not used to this appliance as I am from the UK however:

As hall sensors are used on direct drive machines the hall sensor is located on the back of the drum underneath the big round metal motor part, this will need to be taken off to gain access to the hall sensor. (this is how it works with the LG hall sensors as they are also direct drive)

Trouble Code: P0343

Camshaft Position Sensor High Input

Possible Causes:


CMP (Hall) sensor signal circuit is open or shorted to ground.CMP (Hall) sensor ground circuit is open.CMP (Hall) sensor power circuit is open (check fuse in the I/P).CMP (Hall) sensor is damaged or has failed.PCM has failed.The other code is not listed in this listing.

Okay; This will essentially be a Hall Sensor fault. The Error code (E3) Is issued when the Motor control board is attempting to drive the motor (during the spin out), but is not seeing any tachometer response readings. The Hall sensor monitors such movements to relay the necessary rotation information to the Motor control board. When the Hall malfunctions, the MCB will assume that the motor is "locked" and it will issue the (E3) code.

The necessary actions are to replace the Hall sensor. Here is a picture of the Stator(Motor) and Hall sensor.

Click here to access the service/repair manual for your unit. This manual will help you disassemble the affected area. You will first need to remove the rear access panel, before gaining access to the affected section. Once the rear panel is removed, focus on page 33-34 to help with removing the stator so that you can replace the damaged hall sensor. Please allow time for the manual to download, due to its size.

• Once you have replaced the defective Hall sensor, the unit will return to its normal operating status.

No. Actually, the Hall sensor, part number 6501KW2002A, is covered by a 7 year part warranty.

This is caused by an error from the hall sensor on the motor. It is possible that one of the connectors has come loose (this is an issue with LG's or it could be the hall sensor it's self is bad. First check that the harness that connects to the motor is tight. If that doesn't help then the hall sensor will have to be replaced. The hall sensor is located on the motor. The hall sensor basically tells the computer which direction and what speed the drum is turning.

The hall sensor is located in the back of the washer.  You need to get through the back panel to get to the hall sensor.
