2014 Chevrolet Traverse Check Engine Light in Murray, UT

It means the engine computer stored an OBD-II trouble code indicating a fault in a monitored system.

The light can signal anything from a loose gas cap to sensor or emissions issues. The code identifies the affected system, but confirming the failed part requires systematic testing. In Murray, our team reads freeze-frame data, verifies the condition, and documents the cause so repairs solve the problem the first time.

• OBD-II code read with freeze-frame
• Visual checks for EVAP cap/hoses
• Schedule a diagnostic

Common causes include EVAP leaks (P0442/P0455), oxygen sensor faults (P013x/P015x), MAF issues (P0101), catalytic converter efficiency (P0420), and misfires (P0300).

Age, mileage, and local driving can contribute to these faults. Small EVAP leaks often follow refueling; MAF or O2 sensor faults may show rough idle or poor MPG. Early diagnosis helps prevent catalytic converter damage and failed emissions tests.

• EVAP leaks after fueling
• Rough idle or hesitation
• Poor fuel economy or sulfur smell

A steady light means drive cautiously to service, but a flashing light means stop to avoid catalytic converter damage from a severe misfire.

If the light is steady, reduce load and schedule the soonest check to protect components. If flashing, pull over safely and consider towing to prevent overheating the converter. Our Murray team can prioritize flashing-light cases to limit risk and downtime.

• Steady: limit speed/load
• Flashing: stop and tow
• Book now for next availability

No—resetting sets OBD-II monitors to Not Ready, and Utah emissions testing won’t pass until readiness completes.

Clearing codes erases data inspectors use to confirm system health. Completing the manufacturer drive cycle allows monitors to run self-tests. A verified repair restores readiness more reliably than repeated resets.

• Avoid disconnecting the battery
• Complete the GM drive cycle
• Schedule diagnosis to fix the cause

Larry H. Miller Chevrolet Murray at 5500 S State St, Murray, UT 84107 performs dealer-level diagnostics with OEM tools.

We serve Salt Lake City, South Jordan, West Jordan, Midvale, and Sandy with appointments that help you get in and out efficiently. Walk-ins are welcomed as capacity allows. Check current offers before you visit.

• Schedule service
• Service specials
• Genuine Chevrolet parts and software

A free scan reads generic OBD-II codes, while our dealership diagnosis uses factory data, guided tests, and verifies the actual failed component.

Codes often have multiple possible causes, so guessing can waste time and money. Our technicians access Chevrolet-specific parameters, perform smoke tests and circuit checks, and road test with live data before writing an estimate. The result is a documented fix you can trust.

• Factory scan tool access
• Pinpoint testing and verification
• Written estimate before repair

Accurate diagnosis takes more than a quick code read. Our Murray service department captures trouble codes, freeze-frame data, and system snapshots with factory scan tools that generic readers can’t match, then confirms the fault through guided testing. That depth matters because a single code can have multiple root causes. We support drivers from South Jordan, West Jordan, Midvale, Sandy, and greater Salt Lake City—whether the light appeared after refueling or during a mountain-pass commute. After testing, we explain what failed, why it failed, and how to prevent a repeat. You’ll leave with documented results and a written estimate so you can decide next steps confidently. Find us at 5500 S State St, Murray, UT 84107. Ready to move forward? Schedule your diagnostic and review our service specials before your visit.

We begin with a brief interview to capture symptoms, conditions, and recent events (like refueling). Next comes an OBD-II scan to retrieve codes and freeze-frame data, verification of the concern, and a check for applicable Technical Service Bulletins. We then isolate the root cause rather than chasing the code: inspect intake plumbing and the mass airflow sensor, smoke-test the EVAP system for leaks, evaluate oxygen sensor response and fuel trims, and test ignition or fuel delivery if a misfire is present. When needed, we perform pin-out checks, circuit voltage-drop tests, or a controlled road test with live data recording. Once confirmed, we review repair options and parts availability and provide a written estimate before any work begins. Ready to proceed? Schedule service and review our service specials.

Modern OBD-II systems on the 2014 Chevrolet Traverse can trigger a light for many reasons. Examples include P0300 (random misfire), which can overheat and melt the catalytic converter if ignored; P0420 (catalyst efficiency), sometimes a result of sustained misfires or sensor issues; P0442/P0455 (small/large EVAP leak), often from a loose gas cap or cracked hose; and P0101 (MAF performance) or P0171 (system too lean), which can point to unmetered air or sensor faults. Driving with these faults increases repair costs, reduces fuel economy, and may lead to failed emissions tests. Address issues early to protect the converter and maintain performance.
