B1375 - FAULT CODE - OBD2

B1375 - OIL CHANGE LIGHT OPEN CIRCUIT

The oil change light is used on all cars to warn the driver that it is the most opportune time to change the oil. On certain models, this light may also illuminate when the oil level is not what is necessary for proper engine operation, although on newer models there are separate lights that indicate such situations. Regardless of the case, this light is an extremely important factor, taking into account that, if the necessary attention is not paid to it, the life of the engine could be at stake.

The PCM (Powertrain Control Module) continuously monitors the operation of the oil change lamp. If it does not meet factory specifications due to an open circuit, the B1375 OBDII fault code will be set.
