What does this fault code mean?
The control module (ECM) receives the fuel temperature from the injectors over LIN communication and compares it with calibrated limits. The code is set when the temperature from the injector on cylinder 3 falls below the lowest permitted value, and the control module then uses the temperature from one of the other injectors instead.
Possible causes
- Looseness or oxidation in the connections
- Damaged injector on cylinder 3
What you can do
- 1If there are codes for missing or faulty communication with the injectors, fix those first, as this code is then a follow-on fault
- 2Check the injector connectors, especially on cylinder 3, for looseness and oxidation
- 3If you have a diagnostic tool: read the temperature from each injector in live data and see whether cylinder 3 is low compared with the others
- 4If no fault is found in these checks, the injector on cylinder 3 may need to be replaced, which is a workshop job
Symptoms you may notice1
- No noticeable symptoms for the driver
What the fault can affect1
- The temperature from one of the other injectors is used instead
General guidance for car owners. Diagnosis on the car can point to a different cause.
