P2568Direct Ozone Reduction Catalyst Temperature Sensor Circuit 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
- P2568 is the plausibility check of the sensor on a direct ozone reduction (DOR) radiator, whose coating converts ozone in the cooling air. VW's 2014 specification books for the CC and Tiguan set it on a failed ID check or a failed functional check of the temperature sensor. VW Tech Tip 19-12-01 explains that on 2009-2015 Eos, Jetta, GTI, Passat and Tiguan with the 2.0 L TSI (CCTA, CBFA) this code refers to the radiator identification sensor G611; a new radiator comes with the sensor packed separately, to be bonded on. A non-coated aftermarket radiator or an unbonded sensor therefore triggers P2568. P2569/P2570 are LIN electrical faults, P2567 the general circuit fault. CARB section (e)(14) requires DOR monitoring.
- What you may notice
- Check engine light, often after a radiator replacement
- No change in driveability or engine cooling
- Possible failed emissions inspection
- Likely causes
- LikelyAftermarket radiator without ozone coating or without the identification sensor
- PossibleIdentification sensor not bonded after radiator replacement
- PossibleIdentification/temperature sensor failed its self-test
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
