Possible causes
- Damaged wiring to the vacuum pressure sensor
- Damaged vacuum pressure sensor
What you can do
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Look for damage in the wiring to the vacuum pressure sensor
- 3Have a workshop replace the vacuum pressure sensor if it is damaged
