What does this fault code mean?
The engine control module monitors the exhaust gas temperature. The fault code is set when the engine control module detects that the signal is faulty, and in this case the signal is below the permitted range. The code is linked to ECM-P062B85, which concerns the signal above the permitted range.
Possible causes
- The same signal fault as ECM-P062B85 refers to
- Damaged temperature sensor
- Contact resistance or oxidation in connections
What you can do
- 1Check that the fuses are intact
- 2With the ignition off, check the connectors at the temperature sensor for contact resistance and oxidation
- 3If you have a diagnostic tool: read the status of the code after the repair and see whether it has cleared
- 4Have a workshop check the temperature sensor and its wiring if the fault remains
Symptoms you may notice1
- No noticeable symptoms for the driver
