Replace your vehicle’s oxygen sensor(s)
This sensor determines the level of oxygen in the exhaust to assist the engine to run at maximum efficiency.
Replace catalytic converter(s) with new OE catalytic converter(s)
This warning is usually seen in older vehicles that have not kept up with regular servicing.
Inspect for loose fuel cap and tighten or replace as necessary
Even a loose fuel cap can trigger the engine light. If this is the case, the fuel cap may need to be tightened or replaced.
Replace ignition coil(s) and spark plug(s)
These two problems go hand in hand. If a problem occurs with the ignition coil, this can then have an effect on the spark plugs.
Replace thermostat
This can be a common problem in high heat regions as the thermostat is a hard-working component within a car’s engine.
