Hi,
Happy new year to all
I want to ask you about pins (on ECU) for lambda sensor?
I have CR-V 1999 year, 2.0i. On some users manual i found that i have 2
lambda sensonsor, but i change my catalytic converter and there isn`t 2nd
lambda sensor on it. I only have lamba with 4 pins (2 for signal and 2 for
heating) before catalytic converter.
But i have LPG system and have problems with "check engine" light, so i want
to use lambda simulator/emulator, but i don`t know where (on ECU) is
connected lambda sensor.
Can somebody help me with this?

Regards

 

sounds really complicated

good luck

 

He wants to know which pins on the ECU are for the primary oxygen sensor.

 

Actually he wants to know the pins for the secondary O2 sensor so he can install the O2 simulator since he has a check engine light from not having the secondary O2 sensor in his exhaust since his cat change.

 

I'm guessing from the way the post is written along with some of the wording that the OP isn't in north america, although I could very well be wrong. Most other countries only had a primary O2 sensor and no secondary. OP, what country are you in?

 

Just get the secondary o2 plug and trace the wires (colors) back to the ECU
