2002 toyota tacoma 193833 miles

i am the only owner of my 2002 Tacoma
for he last 10 years i had the same error codes, should i get them fixed?
P0420, P0440, P0446 , and P1135.
also my air bag light is on.
any suggestions
thanks

 

Welcome to TacomaWorld
Replacing the air/fuel sensor B1S1
may cure the P0420 and P1135.
The other 2 are EVAP codes that could be Gas cap O ring, leaking vacuum hoses, VSV switch (s), charcoal cannister, gas tank or filler neck.
EVAP codes don't affect performance they are pollution controls to contain fuel vapors.

Welcome to the TW

 

thanks
I have replaced the twice. the air leak is some where.
what should a check of the leaking vacuum hoses, VSV switch (s), charcoal cannister cost $$$$$
I am concerned that the air bag light is on.
thanks for the warm welcome.

 

welcome! unfortunately may have to bring it to someone to check the airbag light.

 

Hi welcome to tw you need to add cleaner to you gas catlitic converter. I use to work for emissions that's what you need to do. Good luck air bag light probably the sensor.

no need to to check air bag lite.
