12 Indicates the end of one pass through the fault list.
14 ECT Sensor Input The low level normally appears if the coolant sensor wire is shorted to ground.
15 The ECT sensor input is high if the coolant sensor wire is disconnected or the wire is broken.
16 ECT too high a coolant temperature, measures an excessive temperature or is short-circuited or on the weight sits.
22 Throttle sensor. Input signal line InputLo TPS1 in the break
23 The throttle input sensor TPS1 is shorted
24 Sensor of the throttle valve TPS. Sensor malfunction
25 Throttle valve temperature sensor TPS Sensor malfunction
26 ETC the supply wire of the ETC sensor in the breakage or the throttle plate sticks out inside the throttle body
27 The projected difference in TPS TPS 1 differs from the calculated position
