P107B on Lexus
On Toyota and Lexus hybrids, fuel rail pressure sensor B reads out of range
Severity: Severity not verified — if the car runs badly, have it inspected
The Toyota and Lexus bulletins say only that the check engine light comes on with this code; they do not rate how safe it is to drive.
It gets more serious if:
- Inspect soon: Get it inspected soon if the engine stalls, runs rough or loses power.
This page covers only what differs on Lexus. For what P107B means, the ranked causes and the test order, see the P107B guide.
