Hi, I'm Billy and i will be assisting you through this...
So did you read my question?
yes i have and i'm preparing you a detailed answer
so it seems your problem is with the o2 sensor heater control and not with the sensor itself
I need to fix this car today.
open the fuse/relay box and check the o2 sensor relay (which is for heating control only)
Where is it at?
Or I should say which one. Is it under the hood?
yes under the hood driver side
does contain a legend to know which relay i'm talking about
do I have time to go check and you will still be online?
Ok I will be right back
Ok so the legend for the relays EHPS, ABS2, ABS MTR, ABS SOL, EHPS, FAN 3, FAN 2, FAN 1 Which one?
is your mr2 a 1.8 or 2.0?????
I am not sure it is a 16 valve VVTI
The model # XXXXX XXXXX
so it's the newer 1.8 engine
I am not sure we bought it used and that is what the manual says it is. Is there a way for me to confirm?
ok so forget about the relay.......check for o2 or ecu fuses
Those would be in the side panel next to the stering wheel?
to confirm the model number is XXXXX on the front of the cylinder block
no these fuses should be in the engine bay .....but check both boxes to be on the safe side
Oh just to add I have verified that there is 12v going to the bank 1 sensors but have not checked the bank 2.
oh.......makes all the difference
are you still getting three error codes after reinstalling the two bank1 o2 sensors?
Yes but only after a period of time. I disconnected the battery to reset the computer, my wife drives this car short distances perhaps 10 miles a day. She drove it all day without the light coming on all day and then when i got in it to drive it 130 miles the light came on as I was backing out the driveway. My friend has a code reader so after work we hooked it up and it gave me all the codes 135, 141 and 155.
then you should replace the third o2 sensor
So how long do I have to accept this answer? I know that I have to go get the part, replace it, disconnect the battery and then drive it 200 miles or so in different conditions in order for all the sensors to reset in order to see if it worked?
you do not have to accept it until you make sure that it worked for you
but when you do kindly accept it and leave gppd feedback
It is my first time using this website so what do I do now?
try the solution i gave you....and when you know it worked click the green accept button.....so i get paid for my time
For more info do not hesitate to contact me. Thank you, Billy
