Catalytic Converters & ABS in Houston, TX

A P0420 "catalyst efficiency below threshold" code means the converter is no longer cleaning exhaust effectively — sometimes from age, sometimes from an upstream problem like a bad oxygen sensor or misfire. We diagnose the real cause so you don’t replace an expensive converter unnecessarily.

ABS (anti-lock braking) keeps your wheels from locking up in a hard or wet-road stop — vital on rain-slick Houston freeways. An ABS light usually means a faulty wheel-speed sensor, a module fault, or low brake fluid; we scan the ABS system to pinpoint it.

Your regular brakes still work, but the anti-lock and often traction-control features are disabled, so stopping on wet or loose surfaces is riskier. Have it checked promptly — we can read ABS-specific codes most parts stores can’t.
