Check engine light? Don't guess. We run comprehensive OBD-II scans to identify the root cause — not just clear the code. Same-day results, honest recommendations.
Our diagnostic process goes far beyond plugging in a code reader. We use professional-grade equipment to scan every system and interpret what the data actually means.
Fuel delivery, ignition timing, emissions systems, sensors.
Shift quality, solenoids, fluid temp, TCM fault codes.
Anti-lock system, stability control, wheel speed sensors.
AC compressor, blend doors, refrigerant pressure sensors.
Alternator output, battery state of charge, draw tests.
Catalytic converter efficiency, O2 sensors, EGR, EVAP.
4WD/AWD modules, traction control, throttle body.
Airbag modules, TPMS, door/window controls, park assist.
These are some of the most common diagnostic codes we see at Desert Ridge Auto. The code is just the starting point — understanding what caused it is what matters.
Many shops clear the light and send you on your way. We identify the underlying cause and explain your options clearly — even if that means some items can wait.
Engine is misfiring across multiple cylinders. Could be spark plugs, coils, injectors, or low compression. Left untreated, it can damage the catalytic converter.
Your catalytic converter may be failing. Can also be triggered by a bad O2 sensor or exhaust leak. Requires inspection to determine the actual cause before replacing a pricey cat.
Engine is running with too much air or not enough fuel. Common culprits: vacuum leak, failing MAF sensor, dirty fuel injectors, or a weak fuel pump.
