What are the symptoms?
Reductant dosage too low, resulting in exhaust emissions that are too high.
How to fix Scania EME fault code 5889?
- Check fault codes relating to the fuel system and gas exchange system.
- Run Exhaust gas aftertreatment, particulate filter function test, which contains a side-by-side comparison of the temperature sensors.
- Check whether the exhaust system has been tampered with.
- Check exhaust gas pressure sensor T125.
- Check whether the gas exchange system is leaking.
