Question

I have error code P1633 on my 2000 Volvo V70 2.4L Turbo, what does that mean?

Answer 1

The P1633 code indicates an error message is sent to the Engine Control Module (ECM) if a fault in the vehicle speed signal has been detected in the Anti-Lock Brake System (ABS) Control Module. You need to inspect the ABS Control Module connector for any damage.
