U0614Lost Communication With Intake Air Temperature Sensor 2 Bank 2
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- This is the bank 2 counterpart of U0613: the downstream intake temperature sensor of the second bank, usually after that bank's charge air cooler or in its manifold half, delivers its value digitally and the controller has stopped receiving it. Typical carriers are TMAP-style sensors whose SENT frames hold pressure and temperature, protected by a CRC and status bits, as described for Infineon's KP276. No manufacturer documents U0614 publicly; even GM's twin-throttle tables, which use U0611 to U0613, leave it out. The code therefore rests on CARB 1968.2, which demands a separate fault code when a digital input stops communicating. P00A5 to P00A9 describe the analog circuit of the same sensor. The engine controller falls back to a modelled charge temperature for that bank.
- What you may notice
- Check engine light
- Little effect on driving, occasionally less boost
- Likely causes
- LikelyWiring fault to the bank 2 combined temperature/pressure sensor
- PossibleBank 2 combined sensor failed
- RareCorroded or oily connector at the bank 2 sensor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €30 – €300
