Question about 2008 Toyota Yaris Sedan

Open Question

My 2007 Yaris sedan has a P2420 code. Toyota wants $700 for the part. I understand it is an O2 sensor assembly. However they will not release the part number to my mechanic. Any way to get this?

look inside your engine compartment towards the back for gas. I've seen fuel lines that have small o-rings go out and cause that smell inside.

2007 Toyota Yaris Sedan check engine light error code P2420


rule 1, P2 means private Toyota code DCT.
where did you see this. on the dash, at autozoned. or where?
where, counts.
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)
data;
Vent valve stuck open (vent)
Following condition met during key-off EVAP monitor:
  • EVAP pressure change when vent valve closed (ON) less than 0.3 kPa-g (2.25 mmHg-g)
that is metric, pressure, convert as you see fit.

  • Canister pump module (Reference orifice, leak detection pump, vent valve)
  • Connector/wire harness (Canister pump module - ECM)
  • ECM
While ignition switch OFF

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.

El ploblema es que prende la luz de las mil y sale el codigo p2420 y p0441


P0441 Evaporative Emission Control System Incorrect Purge Flow
P2420 Evaporative Emission System Switching Valve Control Circuit High

Ambos avisos estan referidos al sistema de emisiones y las valvulas de pruga que lo componen. Revisa alguna fuga en el canister, a veces un caniester defectuoso causa falla en las valvulas.

Se pueden hacer unas pruebas inyectando gas a presion para detectar posibles fugas.

Aqui hay un TSB (Technical Service Bulletin) referido a estas fallas, aplicable a ciertos modelos 2005.

Espero haberlo ayudado (recuerda calificar esta ayuda) Buena suerte.
