2001 Toyota Sienna Q&A
2001 Toyota Sienna Question: what is the drive cycle for my car?
the drive cycles are drive for 5 mins without touching the brk pedal, then without touching brk pedal coast to 20mph for 2 mmins. repeat as reguired. you must have between 1/4 and 3/4 of a tank of gas and start out stone cold each time. good luc. if this doesn't work something is still wrong - globalhelper
