Hello again.
My weird Galant will never seize to amaze me that it can run and pull great while having half of the stock stuff replaced by crappy fake Peugeot parts or removed entirely.
Me being an electronics tinkerer, I got really interested in O2 sensor and I wanted to get a $12 one to mess around with. While doing some research about them, I got really curious and I thought I should see if I can tap into the one on my Galant. I found the pinouts on the ECU, connected my multimeter, and... nothing. :/
I fully warmed up the engine and still the same 0.0160V which is basically a voltage offset caused by the voltage drop on the chassis ground. It did not respond to my revs.
Naturally, I tried to look for the sensor and see if I could spot a problem like a broken wire or something, and again, nothing.
My car seems to have had its cat removed before it got to my hands since there is nothing that resembles a catalytic converter as far as I know.
Am I looking in the wrong direction or is it really missing?
Where does the harness for the sensor go so I can trace it and hopefully find it tucked into a corner or something?
Can I use a heated O2 sensor from a different car instead and hook up the heater wires to the MPI relay?
I have attached some videos of the underside of the car. Maybe you guys could take a look and point that I was wrong?
Thank you so much <3
