I hate asking for help, but I'm about done beating my head against the wall on this 2016 CX-3 AWD of my Daughters and the BS of where wheel speed sensor connections are etc!
History = her traction control light and tire pressure lights came on simultaneously and the AT light, engine revs up like it's been thrown into neutral and then goes back to normal. Shut the car off, start it back up and the warning lights are all gone and NO codes !
First thing I did was get my one arm down through the engine mess and get the dip stick bolt out, then spent 20 minutes carefully trying to get the plastic POS stick out of the case. Transmission fluid full ! Transmission shifts flawlessly thru all 6 gear in D or running it manually.
I knew her back hubs were done, so I installed two new Mazda rear hub assemblies figuring that maybe the wheel rock was moving the sensor wheel away from the sensor triggering this mess. Thought we were good and then she drove 20 minutes, went grocery shopping and on the way back after turning left this happened again.
Original battery looked like **** and only showed 12.13 volts after me driving it the 25 minutes from her place, so figured I'd put a new battery in her and the troubles would go away as it seems to be a common sensor "fix". I ripped around a traffic circle and it happened to me about 10 minutes into the drive. Again, as soon you shut it off and turn back on codes are gone. I then drove the **** out of it for another 40 minutes without issue yesterday.
This morning I cleaned all the rust scale off the rear drive shafts beside the sensor wheels, thinking maybe it was throwing rust at the sensors. I then drove the **** out of it for over 30 minutes, around the same traffic circle nadda, then down a 5 mile road full of pot holes at 60MPH hammering the **** out of it and still nadda. Starting to grin like a repair guru and then 35 minutes in I turned left hard after a stop sign and ffs, on come the two lights, the AT light blinks, transmission hammers and then off I go just fine. Drive it for another 15 minutes and brake hard at a stop sign and see the AT light blink again. Drive up our laneway and then go around and around in circles and can't make it do it again. Shut it off, start again and warning lights again gone.
I just finished digging through the back to see if the mice chewed the speed sensor wires on this stupidity called a car. You have to damn near remove the rear seat if you wanted to actually change the sensors and run the wire. Nothing looks chewed. Yesterday I checked the front wheel wires and connectors, again in the worst f'n location a designer could find.
Pulling my hair out and I don't have much left and she has my truck. I bought her new Summer tires for this thing for Christmas or at this point I'd be telling her to trade it in. That said she can't afford car payments and I'm trying to buy her time with her on maternity leave and her Husband spending what little they have coming in on smokes and other **** he doesn't need.
Only thing I can think is front right hub is moving enough to trip the speed sensor... but they have no wheel rock or noise that I can feel or hear.
ANY help would be MUCH appreciated! Thanks, Wayne
