Timing depends on the stored Diagnostic Trouble Codes (DTCs) and test results; we give you an ETA after the initial scan and data review.

Some issues on a 2016 Chevrolet Sonic resolve with a quick repair (e.g., gas cap/EVAP leak checks), while others require step-by-step isolation testing. Our process includes freeze-frame data analysis and system-specific tests to confirm the cause, not just the code. Book a convenient time via our online scheduler and we’ll keep you updated as we progress.

• Initial OBD-II scan and freeze-frame data review
• Targeted tests for EVAP, misfire, O2/catalyst, and MAF systems
• Real-time updates and written estimate before repairs

A steady light flags a stored fault, while a flashing light indicates a severe misfire that can damage the catalytic converter.

On a 2016 Chevrolet Sonic, the OBD-II system sets a code that identifies the affected system (EVAP, misfire, oxygen sensor, MAF, or catalyst efficiency). A loose gas cap may be minor; a flashing light is urgent. Our GM factory tools read live data and freeze-frame snapshots to pinpoint the root cause quickly. If the light is on, schedule an appointment in Murray.

• Flashing light = misfire risk to catalytic converter
• OBD-II code identifies the system, not the exact failed part
• Accurate diagnosis prevents repeated parts replacement

Common causes include EVAP leaks (often the gas cap), O2 sensor faults, MAF issues, misfires, and P0420 catalyst efficiency codes.

Your 2016 Chevrolet Sonic’s 1.4L turbocharged inline-4 relies on accurate air-fuel control; even small leaks or sensor drift can trigger a code. We verify causes with smoke testing, live data, and functional checks. Addressing issues early helps maintain fuel economy and protects the catalytic converter. If you’re near Murray, book through our online scheduler.

• EVAP small leak (P0442) or loose/misaligned gas cap
• MAF performance (P0101) or lean condition (P0171)
• Misfire (P0300) or catalyst efficiency (P0420)

If the light is steady, drive cautiously to service; if it’s flashing, stop driving to avoid catalytic converter damage from severe misfire.

Continuing to drive a 2016 Chevrolet Sonic with a flashing light can overheat the catalyst and raise repair costs. A steady light suggests a non-urgent fault, but performance and emissions may be affected. Head to Larry H. Miller Chevrolet Murray for prompt diagnosis and a clear plan. Use our scheduler to reserve a time.

• Flashing = urgent; steady = service soon
• Protects the turbocharged 1.4L engine and catalyst
• Local support in Murray and greater Salt Lake City

• GM factory tools and proprietary data access
• Isolation testing verifies the true root cause
• Written estimate and clear next steps

Your diagnostic begins with a complete OBD-II scan and freeze-frame data capture to see exactly when and how the fault set on your 2016 Chevrolet Sonic. Next, our OEM-certified technicians perform isolation testing tailored to the code category: smoke testing for EVAP leaks, MAF and fuel-trim analysis for lean conditions, ignition checks for misfires, and catalyst and O2 sensor performance tests for efficiency faults. We then confirm the root cause, outline options, and present a written estimate before any repair. Genuine Chevrolet parts help ensure proper fit and long-term reliability. Ready to move forward?

Several OBD-II codes frequently appear on the 2016 Chevrolet Sonic. P0442/P0455 point to EVAP leaks, sometimes as simple as a loose gas cap; unaddressed, they can lead to failed inspections and fuel vapor losses. P0171 and P0101 suggest lean conditions or MAF performance issues that may cause rough running and poor fuel economy if ignored. P0300 indicates random misfires that can overheat and damage the catalytic converter. P0420 flags catalyst efficiency below threshold, often the costly result of prolonged misfire or mixture problems. Bring your 2016 Chevrolet Sonic to Larry H.
