P1054, ABS, and traction light

[Christgen]

Hello, so my 99 s70 threw a p1054 followed by the traction light and ABS light. I'm not sure what the p1054 code is exactly, and the ABS codes are do to a faulty left front signal, missing left front signal, and a faulty pump motor signal. This happened immediately after starting the engine. I believe I may need to replace the front left wheel bearing and possibly the ABS sensor on the same wheel, but I just wanted to know if there was any correlation between the check engine light (p1054) and the pre existing ABS codes. I cleared the engine code and the computer only showed this code again when the ABS and traction light were lit simultaneously. Thanks.

That dtc ties into the abs , it's basically a faulty speed sensor code.

With a faulty abs module on a 99-01 you'll get an abs-0011 then an abs-0010 as your first two codes with a faulty module. It's possible to have a crusty tone ring but that will usually trip an abs-0012 and there's also the possibility of frayed wiring or a loose axle bolt. The wire within the sheath going down to the wheel speed sensor is actually very thing and it will break internally so you would want to verify continuity on that section.
