U0613Lost Communication With Intake Air Temperature Sensor 2 Bank 1
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- Intake air temperature sensor 2 sits further downstream than sensor 1, for example after the charge air cooler or in the manifold, where it is frequently combined with a pressure sensor (a TMAP unit). Digital versions send the temperature together with pressure; Melexis' MLX90818 can carry a medium temperature in its SENT frame and replaces the value with a reserved error code when measurement fails. U0613 means this digitally delivered temperature for bank 1 is no longer received. The only public manufacturer use is GM (23OBDG07/24OBDG07), whose dual-throttle calibration stores U0613 jointly with U0611 when the bank 1 temperature message is lost or stuck high or low, MIL after two trips. P0095 to P0099 are the analog codes. Charge temperature then runs on a substitute value.
- What you may notice
- Check engine light, on GM after two trips
- Possible spark retard or boost reduction as a precaution
- Likely causes
- LikelyDamaged wiring to the combined temperature/pressure sensor
- PossibleTemperature element or electronics of the combined sensor failed
- RareOil from the charge air path in the connector
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.

- Medium · Often possible to do yourself.Typical cost: €30 – €300
