2016 Chevrolet Impala Limited Check Engine Light

The check engine light indicates the PCM stored an OBD-II trouble code that identifies the affected system.

This warning can be minor (like a loose gas cap) or more serious (such as a misfire or catalytic converter efficiency issue). On a 2016 Chevrolet Impala Limited, the light means the computer detected a fault and saved data to help technicians diagnose it. Visit Herb Chambers Chevrolet in Danvers for a precise scan and next steps.

• Light on: system fault stored; light flashing: severe misfire
• OBD-II codes guide testing but don’t name the failed part
• Factory scan tools read live data and freeze-frame for accuracy

Common causes include EVAP leaks (e.g., P0442), O2 sensor or catalyst codes (P013x/P0420), MAF issues, and misfires (P0300).

These faults are typical across many large sedans and can affect fuel economy and emissions. Your 2016 Chevrolet Impala Limited may also trigger the light for a loose or failing gas cap. Our Danvers team isolates the root cause with OEM diagnostics and provides a written estimate before repairs.

• P0442 small EVAP leak often tied to the gas cap or hose
• P0420 catalyst efficiency can follow long-term misfires
• P0300 random misfire may involve ignition or fuel delivery

Yes if steady, but drive cautiously; if the light is flashing, stop driving to avoid catalytic converter damage.

A steady light on a 2016 Chevrolet Impala Limited usually signals a non-urgent emissions fault, but you should schedule diagnosis soon. A flashing light indicates a severe misfire that can overheat and damage the converter quickly. In Danvers, you can schedule service for prompt testing.

• Steady light: reduce load and check gas cap first
• Flashing light: tow the vehicle to prevent damage
• Early diagnosis protects performance and emissions

A parts store provides a free generic code read, while a dealer performs full diagnosis with factory scan data and isolation testing.

Codes point to systems, not definitive failed parts. Our OEM-certified technicians access Chevrolet-specific data, perform guided tests, and verify the fix on your 2016 Chevrolet Impala Limited. You’ll receive a written estimate before any repair.

• Factory scan tools and service information
• Step-by-step testing to confirm the root cause
• Clear estimate and prioritized repair plan

No—clearing codes won’t pass MA emissions because readiness monitors must be completed and fault-free.

Inspection systems check your 2016 Chevrolet Impala Limited’s OBD-II readiness monitors, not just whether the light is off. After clearing codes, monitors reset to “not ready” until drive cycles complete. Fix the root cause first, then allow monitors to set before inspection.

• MA OBD inspection requires completed readiness monitors
• Drive cycles vary by system and conditions
• Address faults first; then verify readiness before testing

Several codes frequently trigger a check engine light on the 2016 Chevrolet Impala Limited. P0442 (small EVAP leak) often points to a loose gas cap or a small hose leak; ignoring it can lower fuel economy and lead to inspection failure. P0420 (catalyst efficiency below threshold) may result from prolonged misfires or exhaust leaks; delaying repairs can risk costly catalytic converter replacement. P0300 (random misfire) can stem from ignition or fuel delivery concerns; left unresolved, it can overheat and damage the converter. Oxygen sensor codes (P0131–P0161 range) can skew fuel trims and harm efficiency.
