Co oznacza ten kod błędu?

The engine control module (ECM) continuously compares the temperature from the front and rear catalytic converter temperature sensors. The fault is set if the difference between them becomes too large, or if the front sensor signal rises too quickly after start.

Możliwe przyczyny

Play, contact resistance or oxidation in the connections to either temperature sensor
Open circuit or short in the wiring to either temperature sensor
Damaged temperature sensor

Co możesz zrobić

1Read the fault code, clear it and test drive to see whether it returns
2Check the connectors of the front and rear temperature sensors for play, contact resistance and oxidation
3Check the wiring to the temperature sensors for breaks and shorts
4If you have a diagnostic tool: compare the temperatures from the two sensors in live data with the engine running; the difference should be small after a short drive
5If the wiring is fault-free: have a workshop check the temperature sensors
