Question about Toyota Yaris
Check engine light came on on my 2007 Toyota Yaris Error code P2420 what does it mean? We just completed a 1550 mile road trip to Virginia. Car is running good. It has less than 57,000 miles. I have regular maintenance done on it. Oil changes, air & pollen filters, tire rotation & wheel balances
Rule 1, P2 means private Toyota code DCT.
where did you see this. on the dash, at autozoned. or where?
2420 means EVAP failure.
bar stool, the gas tank vents are SNAFU'd or FUBAR.
they leak. that is the purpose of evap is to stop fuel fumes from leaking to our fresh air.
and runs test full time. to make that happen.
if it fails the car will not explode or do something dangerous.
i never use forums to find truth here, as most are full of rumor and bull.
i use real Toyota data (the FSM)
Vent valve stuck open (vent)
Following condition met during key-off EVAP monitor:
the PCM toggles the vent valve. and expects a .3kPa change.
id say tighten the gas cap, and reset the eCU, with any scan tool.
see if it comes back, costs zero, effort 5min.
then if it comes back check cap for damage or replace it.
if that dont fix it you will need to test the system.
the FSM covers all that. doing leak down tests, etc.
do you want to do that?
yes, then log in to alldata.com and read.

I had same problem and my repair shop just replaced a sensor in the tranny. Said it was a defect by Hyundai,but they won't recall it.

No one can tell you what other problems you would have, they would be playing GOD. Anyway the crank angle sensor is built into the distributor and you should change it asap. An option is to get one from a junk/used car yard. If you wanted it re-manufactured Autozone will have it with lifetime warranty.

Your vehicle is equipped with a timing chain. There is no periodic maintenance schedule fr the timing chain.
If your spark plugs have never been changed, now might be a perfect opportunity to change them. Ensure that you properly gap the plugs before installation. You will find gap specs on the engine information tag/sticker under the hood.

The maintenance schedule is an outline and should be followed if you want to keep your vehicle in good condition. the maintenance items listed in the schedule are performed at their set intervals for a reason. Manufacturers have found the wear limits on certain parts and those parts may need to be serviced or replaced at those intervals or catastrophic failures may result.
