Was bedeutet der Fehlercode?

The fault is intermittent, meaning it comes and goes. The ECM checks the signal from the rear sensor at the catalytic converter against a calculated value, and the code is set when that signal is noisy.

Mögliche Ursachen

Contact resistance or oxidation in the connections
Damaged exhaust temperature sensor after the catalytic converter

Was Sie tun können

1Check that the fuses are intact
2If the fault is intermittent: check the wiring to the sensor where it can be reached, and see whether the code returns when it is moved
3Check that the connections to the sensor are free from oxidation and contact resistance
4If you have a diagnostic tool: read the fault status after a test drive to see whether the fault is active at that moment
5If the fault remains or returns, have a workshop check the sensor after the catalytic converter

Symptome, die Sie bemerken können1

Check engine warning lamp lights or behaves abnormally

Was der Fehler beeinflussen kann2

No exhaust gas recirculation (EGR) control
Soot particles are not burnt off
