Hall Sender G40 And Hall Sender 2 G163 Both Hall senders are located in the timing chain cover. The have the task of informing the engine control unit of the positions of the inlet and exhaust camshafts. They do this by reading the quick start sender rotor located on the respective camshaft. With Hall sender 1 G40 the engine control unit detects the position of the inlet camshaft and with Hall sender 2 G163, the position of the exhaust camshaft. Use of signal The engine control unit uses the engine speed sender signal to detect the position of the crankshaft. With the signals for the camshafts in addition, the control unit calculates the position of the camshafts relative to the crankshaft. The control unit needs these positions for the precise adjustment of the camshafts and to start the engine quickly. Consequences of loss of signal If only one Hall sender fails, camshafts will not be adjusted. But the engine will continue to run and will start after it has been stopped. If both Hall senders fail, the engine will continue to run until the next time that it is stopped. It will not be possible to restart the engine Coolant Temperature Sender G62 The coolant temperature sender G62 is located in the thermostat housing. It informs the engine control unit of the current engine temperature. Use of signal The sender signal is used for temperature- dependent start of camshaft adjustment. Consequences of loss of signal the signal fails, the control unit uses a if substitute temperature stored in it
