A code from the parts store tells you a sensor saw something. It doesn't tell you why. Honest & Affordable Auto comes to your home or office in Brevard County with professional diagnostic equipment, reads the code, then actually tests the circuit or the part behind it. You get the real cause and a quote to fix it, before we do anything.
P0420 doesn't always mean a catalytic converter. P0171 can be a vacuum leak, a dirty sensor or a weak fuel pump. Throwing parts at a code is how people spend real money and keep the light on. We test live data, look at fuel trims and misfire counts, and check the wiring before we name a part.
Evap system leaks from heat-cracked hoses, oxygen sensors that quit after years of humidity, ignition coils and plugs on cars that idle in traffic on 192 and Wickham, and cooling-system codes on anything that's been through a few Florida summers. Most of these are fixable in the driveway the same day.
A steady check engine light means schedule it soon. A flashing one means active misfire and you're feeding raw fuel into the exhaust, which can wreck the converter in a few miles. Park it and call us. We come to the car.
Yes. Honest & Affordable Auto brings a professional scan tool to your location anywhere in Brevard County, reads the codes, tests the systems behind them, and quotes the repair before doing any work.
No. Reading the code takes thirty seconds. The diagnostic is testing what the code points at so you fix the actual failure instead of replacing parts on a guess. That's the difference between a parts-store scan and a mechanic.
If it's steady, usually yes for a short time, but get it looked at soon. If it's flashing, stop driving. A flashing light means active misfire and can damage the catalytic converter quickly.
