I bought O2 sensor from Autozone, P/N Bosch 15712 for 93 LX with 5MT. For some reason I don't think it is working. What is the part number for genuine honda part?

 

36531-PT3-A12

 

I did some more research and found that this car has two sensors. I did not know. Autozone and Advance Auto list only for the pre-cat sensor. I thought it has only one. Have any one changed both of them?

36531POAA01 and 36532P8DJ01 are the numbers I found.

 

Hi Hondadude,
Is it for front or back?

 

Hmm 93 is OBD 1 and does not have a monitor sensor after the Cat;
But if some AFTERMARKET bull crap website says that the Hondanet Dealership parts dept program is Wrong. Then I guess you are right.
Good bye Have a nice life.

Put in your dealership ID number and then your American Honda technician number and your password.
Then look it up yourself and come back here, shooting off about how other people didn't look up information at AUTOZONE

 

Walker Products who makes O2 sensors says this car is equipped with two sensors. At the same time, they do not say Hondanet is wrong, either.

I'm not a Honda Dealer. I'm not a Honda Tech. If I was, then I won't be asking these questions. I don't have to seek help from others.

I had a simple question and I asked that question. That is all.

 

Sry, but Honda Dude is right....
You were right too when you thought it had only 1
Sometimes those general automotive shops make mistakes too.

Btw...Have you ever thought of poking your face underyour car and actually looking ?

 

I have been under the car during some workwere under way. I did not notice O2 sensor in aft of cat. But then, I was not paying attension.

I will have a look at it, today.

 

According to Haynes Manual, there should be resistance between two terminals for heater coil on this O2 sensor. I checked resistance and it is open circuit. With sensor still in place, I run engine to monitor voltage on other terminal as the manual says. Voltage reading was not stable and not corresponding to rpm change.

 

I went back to the place I bought the sensor. Checked a sensor on their shelf for heater coil and it was open circuit, just like what I have. I could not check for voltage, though.
