P00DAAmbient Air Temperature Sensor Circuit B Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- Ambient air temperature sensor B is a second, separate ambient temperature circuit in addition to sensor A. What the second measuring point is used for in a given vehicle could not be documented; the value may be wired directly to the control module or come over the data bus. Regulations require monitoring of such inputs because ambient temperature is often an enabling condition for other diagnostics. None of the manufacturer documents searched uses these codes; the explanation follows sensor A. P00DA: This is a plausibility fault: after a long standstill the reading is compared with other temperatures, which should then agree.
- What you may notice
- Wrong or missing outside temperature display
- Climate control regulates incorrectly
- Check engine light on (manufacturer-dependent)
- Likely causes
- PossibleSensor in a heat-affected position (engine, sun)
- PossibleComparison sensor faulty
- PossibleSensor drifting
- RareControl module faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €50 – €150
