While you're cruising in your 2011 Honda Odyssey, you might notice a warning light pop up on your dashboard. This is a common occurrence and typically signals that it's time for a regular check-up on your fluids and vehicle parts. If it's the check emission light, it's often triggered by a loose gas cap or a leak in the evaporative system. On the other hand, it could be due to a faulty charcoal canister, a malfunctioning fuel pressure regulator, or a failing throttle position sensor. Any malfunctioning component will ultimately require replacement. A new regulator could range from $30 to $130, and a new throttle position sensor might cost you anywhere between $50 and $140.
