Will An Exhaust Leak Cause A Check Engine Light?

Yes, an exhaust leak can trigger a check engine light. Upstream leaks skew oxygen and NOx sensor readings, causing the ECM to adjust fueling and set fault codes. You may also notice ticking, soot at joints, or fumes. Fix the leak promptly to protect components and restore proper trims.

How Long Should A Truck’s Exhaust Last?

Service life varies with duty cycle, mileage, and environment. Frequent short trips, corrosion, and heat cycling shorten lifespan, while stainless components and good hangers extend it. Watch for leaks, rust, or failed flex sections during inspections. Addressing small issues early prevents expensive aftertreatment damage and avoidable downtime.
