In Billerica, a warning light is often the aftermath of an impact. Pothole hits damage wheel-speed sensors, their wiring and their tone rings, and the result is an ABS, traction-control or stability-control light that appears a day or two after the hit.
What Diagnostics & Check Engine Covers
- OBD-II and manufacturer-level scan tools
- Drivability and intermittent fault diagnosis
- Electrical, sensor, and emissions troubleshooting
- Detailed report of findings and recommended repairs
- EV diagnostics including Rivian
Wheel-speed sensors sit at the hub, right where road debris and impacts reach them. A cracked sensor, a bent tone ring, or a chafed wire produces a signal the module rejects, and modern systems tend to disable ABS, traction control and stability control together — three lights, one cause. Reading which wheel the code names and then verifying the signal is what separates a sensor replacement from a wiring repair.
Tire-pressure sensors take the same abuse. An impact can damage the sensor inside the wheel or knock it out of calibration, and a slow leak from a bent rim will set the light for a completely legitimate reason. We check the pressures and the wheel before assuming the sensor is at fault.
We test the circuit, not just the code. Call for current pricing.
Billerica Questions About Diagnostics & Check Engine
- Three warning lights came on after I hit a pothole — is that one problem?
- Often, yes. ABS, traction and stability control share wheel-speed sensor data, so one damaged sensor or wire disables all three. We identify which wheel is reporting and verify the signal.
- My TPMS light came on after a rough road — sensor or leak?
- Either. Impacts damage sensors and also bend rims, which causes real slow leaks. We check actual pressures and wheel condition before replacing anything.
