Will a dirty air filter throw a code?
Let’s just say it’s been a while since I’ve cleaned or replaced my car’s air filter. Can a dirty air filter trigger an error code?

A dirty air filter will throw a code or set off the
check engine light
. The dirtier an air filter is, the more it can limit your engine’s air intake. A limited air intake to your engine can throw off the air to fuel ratios and create what’s known as a rich air/fuel mixture. A rich air/fuel mixture can cause all sorts of damage to your engine, like misfires and busted spark plugs. You should double check your owner’s manual to be sure, but generally, you should replace your air filter every 12,000 to 15,000 miles to prevent it from mucking up your engine.
