169000708 - Z88 LONGITUDINAL ACCELERATION SENSOR ERROR

The diagnostic equipment signals the following error: "C1335 - Longitudinal acceleration sensor"

This error is signalled if the sensor output voltage is below 0.3 V or above 4.7 V or if the yaw sensor supply voltage is more than 5.3 V or less than 4.7 V or if the value sent by the sensor is not plausible. This means that there is an open circuit or short circuit (positive or earth) for the sensor or the wiring, that the sensor is mechanically damaged or that the reading circuit is damaged.

1	ELECTRICAL CHECKS	All OK	Problems encountered	Operation
	Check that the longitudinal acceleration sensor supply voltage is between 4.7 and 5.3 V See E7023 ESP Vedere Prova 3350ED VERIFICA SENSORE DI ACCELERAZIONE LONGITUDINALECheck that the longitudinal acceleration sensor output voltage (longitudinal acceleration sensor) is in the range between 0.3 and 4.7 V	Move on to Step 3 1	Voltage not correct at accelerometer	Move on to Step 2 1
2	ELECTRICAL CONNECTION CHECK	All OK	Problems encountered	Operation
	Check that the electrical connections between the acceleration sensor and the ABS control unit are correct	Move on to Step 3 1	Wiring faulty Sensor not correctly fastened	Renew the wiring and move on to Step 3 Restore the correct fastening for the sensor and move on to Step 3
3	CHECK ON CORRECT OPERATION	All OK	Problems encountered	Operation
	Delete the errors using the diagnostic equipment.Carry out a road test Vedere Prova 3350EA VERIFICA DI INTERVENTO SISTEMA ESPto ensure that the control unit checks whether there are any errors still present.Return to the workshop and check that the fault is no longer present using the diagnostic equipment	End of diagnosis	The fault persists	Move on to Step 1
