Volvo models this fault code applies to
Applies to the following models:
1 modelV60 (2011–)
Show models by year and engine (2)
What does this fault code mean?
On the V60, the module has found that the vacuum pressure sensor in the brake booster is sending a wrong reading. The module compares the vacuum with the air pressure to assess how the brake booster is working, and when the signal is wrong, the assist functions can be affected.
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
- 4The braking system is safety critical: do not work on the brake booster or sensor yourself; leave this to a workshop
Symptoms you may notice1
- No noticeable symptoms for the driver
