$129–$149 is the typical diagnostic fee range at many dealer service centers; fees are often credited toward repair.

Larry H. Miller Chrysler Jeep Dodge Ram Sandy posts up-front pricing and explains what the diagnostic covers so you can decide before work begins. Dealers can perform factory-level scans that reveal freeze-frame and manufacturer data that a free parts-store readout won’t show.

• Up-front diagnostic fee disclosed before testing
• Factory scan tools access freeze-frame and module data
• Diagnostic fee frequently credited to the repair estimate

Most complete diagnostics for a vehicle like the 2016 Dodge Challenger take about 60–90 minutes from scan to written estimate.

That timeline covers an initial OBD-II scan, freeze-frame review, basic isolation testing and a written repair estimate; complex intermittent faults can require additional time. If you’re driving in or near Sandy Auto Mall, plan accordingly and use our online option to schedule service.

• Initial scan and freeze-frame review
• Isolation testing and functional checks
• Written estimate before any repairs begin

The check engine light signals one or more OBD-II trouble codes (for example, P0300 indicates random/multiple misfires).

The light is a symptom, not a diagnosis; the code tells which system reported the fault and points technicians toward the likely cause. For a 2016 Dodge Challenger we first review freeze-frame data and module readings to determine whether the issue is an emission component, ignition, or fuel delivery fault.

• OBD-II codes identify the affected system or circuit
• Freeze-frame data shows engine state when the fault logged
• Further testing isolates sensor vs. mechanical causes

Common causes include oxygen sensor failure, EVAP system leaks, mass airflow sensor faults, catalytic-converter issues, and ignition misfires.

These issues generate distinct codes and symptoms: O2 and MAF faults often affect fuel trim, EVAP leaks can set persistent codes after refueling or temperature swings, and misfires commonly show as P0300–P03xx codes that can damage the catalytic converter if left unaddressed.

• O2 sensor or MAF faults change fuel trims and emissions
• EVAP leaks (loose cap, canister leaks) set emission codes
• Misfires risk catalyst damage if ignored

A steady check engine light can usually be driven cautiously to a service facility, but a flashing light means stop driving immediately.

A flashing light typically indicates a severe misfire that can overheat and damage the catalytic converter; continuing to drive risks more costly repairs. If the light is steady, schedule timely diagnostics so the underlying code can be evaluated and a repair plan provided.

• Steady light: drive cautiously to service
• Flashing light: stop driving to prevent converter damage
• Use written estimates to weigh repair options

Dealer diagnostics use factory-level scan tools and access proprietary module data and technical service bulletins that a parts-store reader cannot provide.

A parts-store code readout shows the code but not manufacturer-specific freeze-frame or module data; dealer technicians can perform isolation tests, consult TSBs, and provide a written repair estimate. Larry H. Miller Chrysler Jeep Dodge Ram Sandy documents findings and explains warranty or repair options before work starts.

• Factory scan tools access deeper module data and freeze-frame info
• Techs can consult manufacturer TSBs and wiring diagrams
• Written estimates and part-source clarity before repair

Engine-light diagnostics for the 2016 Dodge Challenger require more than a simple code read; environmental factors around the Salt Lake Valley can influence fault appearance. Serving Sandy, Draper, and South Jordan, our service team considers local climate: cold starts in winter can surface ignition or sensor errors, while large daily temperature swings can trigger EVAP system faults. We use factory-level scan tools to capture freeze-frame data and read module-specific information that generic OBD-II readers miss.

If a fault is intermittent, our technicians perform stepwise isolation testing to reproduce the condition safely. Bring your 2016 Dodge Challenger to Larry H. Miller Chrysler Jeep Dodge Ram Sandy for an accurate diagnosis — schedule service or view our service specials online.

Our diagnostic workflow for the 2016 Dodge Challenger begins with an OBD-II scan and capture of freeze-frame data to understand the engine state at fault. Next, a technician reviews related module data, performs isolation testing (ignition, fuel, sensors), and inspects likely components. We document findings and provide a written estimate before any repair work starts so you have clear choices and costs.

The diagnostic process typically includes: initial computerized scan, visual and functional checks, targeted sensor and circuit tests, and a transparent repair estimate. To set an appointment, schedule service online or check current offers on our service specials.

Common engine codes on a 2016 Dodge Challenger include misfire codes (P0300–P03xx), O2 sensor codes (P0130–P0167 range), MAF or airflow issues, EVAP system leak codes (P0440 series) and catalytic converter efficiency codes (P0420). Misfire codes left unaddressed can overheat and permanently damage the catalytic converter; EVAP leaks can cause failed emissions tests if not isolated.

Cost implications vary: sensor replacements are generally less costly than catalytic converter replacement, which is the most expensive consequence of ignored misfires.
