full diagnostic deep‑dive (each warning)
⚙️ check engine light (MIL)
issue
emission control, ignition misfire, oxygen sensor, EVAP system, or catalyst efficiency. Common Mirage codes: P0421 (warm up catalyst), P0300 (random misfire), P0400 (EGR flow).symptoms
rough idle, hesitation, increased fuel consumption, stalling, failed emissions test. light may flash under misfire.diagnosis (multiple methods)
- OBD2 scanner – read codes, freeze frame, live data (fuel trim, coolant temp).
- visual: vacuum leaks, damaged wiring, loose gas cap.
- smoke test for evap leaks.
- compression test if misfire persists.
- swap known good coils if misfire code present.
repair cost
$100–$1100parts: O2 sensor $180–350, EGR valve $200–450, ignition coil $120–300, catalytic converter $500–1100.
🛢️ oil pressure (red)
⚠️ issue
low oil level, worn oil pump, clogged pickup, faulty pressure switch, or incorrect oil viscosity.🚨 symptoms
light on at idle (may flicker), engine ticking, overheating, possible low power. sudden loss = immediate stop.🔬 diagnosis
- check dipstick (level & condition).

- test ABS pump operation with scan tool.
💸 cost
$120–$1000sensor $100–250, tone ring $200–400, module $700–1300.
💥 airbag (SRS)
🧨 issue
clockspring broken, front impact sensor, seat belt pretensioner, or corroded connector under seats.🚨 symptoms
airbag light on, horn or steering wheel buttons may fail (clockspring).📟 diagnosis
- SRS scanner (MUT‑III or equivalent).
- check yellow connectors under seats.
- measure clockspring continuity.
- inspect crash sensors for damage.
💰 cost
$150–$850clockspring $200–450, sensor $150–350, module $400–900.
📈 tire pressure (TPMS)
📉 issue
low tire pressure, dead sensor battery, sensor damaged during tire change, or relearn needed.🚙 symptoms
light solid or flashing, pressure warning on display, uneven wear.🔧 diagnosis
- check pressures with gauge.
- use TPMS trigger tool to activate each sensor.
