What does the P2159 code mean and how do I fix it?
Quote from ScanToolGuru on July 15, 2025, 10:11 amI recently scanned my vehicle and got the P2159 error code, which I believe relates to the vehicle speed sensor "B" circuit. I'm driving a Jeep, and I've noticed some issues like a faulty speedometer and inconsistent fuel readings.
Can anyone explain:
What exactly this code means?
Is it safe to keep driving with it?
What are the common causes and solutions for this issue?
Any insights or repair tips would be appreciated!
