What does this fault code mean?
The code is set when the exhaust temperature is too low to preheat the oxygen sensors. This happens when the engine control module self-test runs before the engine has reached operating temperature, so the sensor heating cannot be switched on.
Possible causes
- The engine control module (ECM) self-test was run before the engine had reached operating temperature
What you can do

- 3If the code returns with a warm engine: have a workshop with diagnostic equipment look at the fault in more detail
