Bobcat fault codes

Bobcat hydraulic oil temperature codes climb in three steps on M-Series machines. What each one means, when it’s the sensor, and when it’s a dealer job.

Bobcat M0514 charge pressure code, explained with the full M05xx ladder, nine owner reports, and why a gauge test beats buying a new sensor.

Bobcat M0309 back after a new battery? All three documented M0309 reports we reviewed had a new battery, and the code persisted. Here’s the timing split.

Bobcat M0117 won’t clear with a fresh filter? Bobcat lists it beside M0116 and two derate codes, and each points somewhere different on M-Series loaders.

Bobcat 01-17 is the air filter plugged code; on older loaders 10-17 is the charge filter, and P0117 is an engine coolant sensor fault.

Bobcat 04-15 code lookups disagree because most published lists copy each other. Bobcat’s S220 manual confirms 01-17 as plugged air filter.

Bobcat code lookup starts with the plate serial, not the model name. On an M2-Series standard panel, the information button brings up the active codes.

Bobcat code lists repeat codes: D7509 is a pattern switch fault on an M-Series loader and a park brake fault on a telehandler. Your plate picks the row.

Bobcat fault codes read differently by machine generation. U1201-00 is a remote engine disable, not a failure. Here’s how to tell what stops work.
