Question

2006 Toyota Sienna LE 6 Cyl with engine code P0442, how do I fix it?

Answer 1

Hi there,

P0442 is for a small leak in the evap system. You need to have a smoke test performed to try and locate the leak. This could be a simple issue with the gas cap or something else. The smoke test will located the leak then it can be repaired properly the first time. Would not hurt to try a gas cap on your own however.
