U0465Invalid Data Received From PTO Control Module
- Generic OBD-II code · Network
- How the car detects it
- U0465 flags implausible data from the power take-off (PTO) controller. That unit switches in an engine-driven output for dump beds, aerial lifts or pumps and asks the engine for a working speed. The engine or body controller logs it when PTO state or speed requests arrive corrupted or contradictory. GM uses the code: Saab's U-code tables for the 2011 9-5 and 9-4X, which follow GM's global architecture, list U0465 00 for invalid data from the PTO module, without timing or lamp rules. CARB lets the engine controller suspend monitor counters while a PTO runs, so a trusted PTO status matters for OBD bookkeeping. Caution: a Ram 1500 STAR case (S1908000041) prints U0465 in its title, but its body names U0645, the active air dam. U0117 is lost contact, P064B a PTO module fault. PTO or set speed drops out; no MIL.
