U0113Lost Communication With Emissions Critical Control Information
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Unlike its neighbours, U0113 does not name one unit but a class of data: messages a controller depends on for emission control, for instance torque, speed or aftertreatment status supplied by another node. CARB's OBD II rule wants silence from a digital input recognised as a fault of its own with a dedicated code, and U0113 is the generic slot for that situation. Ford's 2014 five-digit code interpretation for its engine controllers includes U0113; which frames belong to it and how long they may be absent is not published by any maker. Implausible data of the same kind falls under U0441. Because the engine then has to use substitute values, a lit MIL and possibly reduced power are the likely outcome.
- What you may notice
- MIL on
- Engine on substitute values, possibly reduced power
- Further U codes in other modules
- Likely causes
- LikelyFault in the CAN wiring or connectors carrying the emission-related frames
- PossibleSending module without power, ground or wake-up
- PossibleSoftware or configuration mismatch after module replacement or update
- RareReceiving controller internally faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
