| Fault Code Description |
|---|
|
The diagnosis monitors activation of heating at the oxygen sensor before catalytic converter. Malfunction monitoring conditions The fault is detected when there is a line disconnection (break). |
| Fault Code Conditions | |
|---|---|
| General Conditions |
Voltage precondition - Supply voltage between 9 V and 16 V Temperature condition - None Time condition - 10 s after engine on Other preconditions - Engine ON Terminal status - Terminal 15 on |

|
The fault is entered within 10 seconds. |
| Service Plan |
|---|
|
- Eliminate secondary faults, faults for the following components or functions: Check terminal 15 N_1 lines and plug connections between following components: DME Oxygen sensor before catalytic converter - Check oxygen sensor before catalytic converter. - Replace oxygen sensor before catalytic converter. |

|
- The internal resistance of the oxygen sensor heating can be measured when disconnected/removed. A resistance greater than 1000 ohms can be measured between pin 4 (12 V) and pin 3 (ground) in the event of a fault and when the sensor is cold (less than 50°C). - Do not allow plug connection to come into contact with cleaning agents or solvents, oxygen sensor can be destroyed. |
