Right now i have no secondary o2 sensor on my 2000 Si,
First i started out with code 65 (bad o2 sensor).
Recently i checked the codes as my car felt really crappy...
Now i am getting codes for my
1) Air-Intake temperature
2) Throttle position Sensor
3) Engine Coolant Temperature
4) System too Rich

I think its caused by the o2 sensor not being in. Tell me what you think.

 

Have you put in the sensor and tried resseting the ECU? Try that first and see what happens. BTW are you running a test pipe?

 

In fact I am using a test pipe

 

Wrap the second o2 in foil and tie it out of the way. Reset the ECU and take it for a drive. Keep us posted if you get any other codes.

 

o2 simulator, do a search a serach.

the secondary o2 sensor is just there to make sure it's reading clean air.

the o2 simulator tricks it into thinking it is. and no more CEL

 

ok. i installed the o2 sensor. all the codes were gone for about a day, then i got a new code....67...something about the cat not meeting threshold performance...
I have in a test pipe..so i know thats why... i s there any tricks or suggestions to try.

 

testpipes may normally provide better performance, but i suggest installing a Carsound high flow cat for your particular needs. you can have whatever O2 locations you want on it. and better yet it keeps the air cleaner.
