jus sharing my lil 2cents with everyone..
from the first post you can see the problem i had.
I came across a check light and came up with a code po425 which was making my car run lean and i thought was a oxygen sensor,but because the previous owner removed the cat below the car and removed the sensor with it.i couldnt be 100% sure
well after extensive research and some help from raybic(a fellow tuner),i found out that the sensor i was searching for that was causing this code was a egt sensor/probe.
The egt sensor(exhaust gas temperature sensor)is a probe like sensor that goes into the catalyst below the car and monitors the temperature of the catalyst and throws a code if it detects overheating or a malfunctioning cat.
ok enuff explanation.This is the solution
Remove foot rest on driver side,you need a 12" depth to do this
Remove carpet to find this(this is the hole which leads below the car to the cat)
There should be a two pin wire harness which should have a white connector onto it(this is what the egt sensor normally plugs into)
I used a 270 ohms resistor and plugged it into the connector(dis thing is 40cents for the lease by steves in san juan)you will need to disconnect the battery pole to clear the previous code
This is the connector with the resistor in
Once thats done,you mite want to tape it up to protect it from the elements
reverse the process and attach the battery pole,start the car and taaa ddaaa,no more freaking engine check light
This has been the second week and the only amber lights im seeing are traffic lights.
I swear this works
Pls note this fix is for the code po425 which reads as catalytic temperature sensor on OBD11 and is not to be a fix for po135 which relates to one of your o2 sensors(front or rear)
This resistor mod is used for higher end cars such as wrx or evolutions.
You can view the fix as a egt resistor fix here
