FAQs About Emissions Parts

What does the emission (evaporative emissions control, or EVAP) system in a Mitsubishi do?

It manages gases released from the exhaust. Many different parts make one up; they can include an engine computer (an engine control unit or engine control module/ECM), the fuel tank, the fuel line, a control solenoid, a positive crankcase ventilation (PCV) valve, an oxygen sensor (or sensors), and hoses. When the system doesn't work right, emissions increase, your vehicle will start to pollute the environment, and it'll fail an emissions test ("smog check").

Why is my emission system (Check Engine or Malfunction Indicator/MIL) light on?

Some reasons include a clogged air filter, ignition coil failure, a faulty catalytic converter, spark plugs gone bad, engine valve or piston damage, a bad mass airflow sensor, a defective vacuum hose, a loose gas cap corroded wiring and connectors, and a fuel injector going out. Run an inspection to figure out the actual cause.

What happens if I ignore a Check Engine light?

That depends on why it's lit up. Usually, it's because of a part or systems failure of some kind; let one go long enough, and you'll end up at a Mitsubishi dealer for repairs. They can be expensive, so address issues sooner rather than later.

How much does emission system replacement cost on average?

Depending on the part, it can run anywhere from single dollars to thousands. A gas cap replacement, for example, can be cheaper, costing less than $10 in some cases. A purge valve replacement, however, might run $180 to $200. A fuel evaporative canister replacement: between $465 and $520. An exhaust system repair, though, like replacing a catalytic converter? $2,305 to $2,445, and so on. Cost can even vary based on Mitsubishi model.
