Fault code
Meaning of the fault code
(Hex)
possible reason for fault detection
33
Logical error at engine speed input
TCU measures a engine speed over a
threshold and the next moment the
measured speed is zero
Cable/connector is defective and has
bad contact
Speed sensor has an internal defect
Sensor gap has the wrong size
34
S.C. to battery voltage or O.C. at turbine
speed input
TCU measures a voltage higher than
7.00V at speed input pin
Cable is defective and is contacted to
vehicle battery voltage
Cable has no connection to TCU
Speed sensor has an internal defect
Connector pin is contacted to battery
voltage or has no contact
35
S.C. to ground at turbine speed input
TCU measures a voltage less than 0.45V
at speed input pin
Cable/connector is defective and is
contacted to vehicle ground
Speed sensor has an internal defect
36
Logical error at turbine speed input
TCU measures a turbine speed over a
threshold and at the next moment the
measured speed is zero
Cable/connector is defective and has
bad contact
Speed sensor has an internal defect
Sensor gap has the wrong size
37
S.C. to battery voltage or O.C. at
internal speed input
TCU measures a voltage higher than
7.00V at speed input pin
Cable is defective and is contacted to
vehicle battery voltage
Cable has no connection to TCU
Speed sensor has an internal defect
Connector pin is contacted to battery
voltage or has no contact
38
S.C. to ground at turbine speed input
TCU measures a voltage less than 0.45V
at speed input pin
Cable/connector is defective and is
contacted to vehicle ground
Speed sensor has an internal defect
