Invalid Data Received From Direct Ozone Reduction Catalyst Temperature Sensor
A receiving module detected implausible data from the direct ozone reduction (DOR) catalyst temperature sensor. Temperature values fail plausibility checks against engine load and ambient and are rejected.
Affected components
- Dor catalyst temp sensor
Common causes
- High likelihood: Module internal fault or sensor input drift
- Medium likelihood: Software version mismatch after replacement
- Low likelihood: Gateway module routing CAN messages incorrectly
Possible symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- A drive cycle may be required after repair
