Frequent Problems in the Toyota Corolla
If you have the check engine light on in your Toyota Corolla, it could be due to several common faults depending on whether it's a petrol engine (TSI, EcoBoost, VTi...) or diesel (TDI, TDCi, BlueHDi...):
- Blockage in the exhaust gas recirculation systems, which limits engine RPMs.
- Misfires (coils or spark plugs), causing jerking and the P0300 code.
- Dirty or faulty oxygen sensors (Lambda probe), which increase fuel consumption.
