CID 1835 CAT Fault Code

Auxiliary Pressure Sensor

Cause :

Malfunction in the thermostat control system. The on-board computer reports problems with communication with the control unit, so a possible cause may be poor contact. The cooling system circuit is open, which may affect the operation of the power unit as a whole.Associated with low engine fluid pressure. The reason most likely is the lack of oil in the engine, so first of all you need to check the amount of consumable. You should also make sure that the engine fluid pressure sensor is working.


Don't forget ! When a fault code pops up, CAT's Uptime Center is automatically notified via an cellular link, and it alerts the truck's owner by prearranged methods, usually email or phone calls.
