My car's a 2015 Sonic hatchback with a 5-spd and 1.8 engine, and has around 78k miles.
Friday evening, it lit up the ABS and traction control warning lights while I was driving. It tried to reset a couple of times but the pedal would pulse whenever I put on the brakes. Then it would light the warning lights up again.
Saturday, I took it to AutoZone and had them read the codes. It came back with a 0 input on the left front sensor, so I bought a left front sensor and put it on. Everything seemed fine, but I went out again that evening, and when I hit a bumpy stretch of highway, the warning lights came on again.
Today, I made sure the new sensor was seated properly and plugged in firmly. The wire was routed in such a way that it couldn't get pinched or bound up. Everything looks the way it's supposed to, but this didn't solve the problem. So, I went back to AutoZone, and they explained that the codes need to be cleared, so they did this, and showed me on their monitor how it was no longer showing any warning issues with the ABS system.
I started for home, and barely got 1/4 mile away, when the ABS and traction control warning lights lit up again. Needless to say, this is frustrating. I can probably take it to a shop sometime this week, but am curious if there's anything else I can try to do in the meantime.
Edit: I just checked the resistance on the old sensor, and my old style, non-digital multi tester is showing around 1500ohms, which from what I've read, sounds like the sensor itself may have been ok, but there's a problem with the wiring.
Thank you,
