What U0613 means
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.
U0613 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0613
- Check engine light, on GM after two trips
- Possible spark retard or boost reduction as a precaution
Common causes of U0613
- Most likelyDamaged wiring to the combined temperature/pressure sensor
- PossibleTemperature element or electronics of the combined sensor failed
- Less likelyOil from the charge air path in the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note U0613 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0613
What does U0613 mean?
U0613 means "Lost Communication With Intake Air Temperature Sensor 2 Bank 1". 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). It is a generic code, so it means the same on every make.
Is it safe to drive with U0613?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will U0613 fail an emissions test?
Yes, it can. U0613 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is U0613 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will U0613 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
