#1967 of 2107 1992 Honda Accord Oxygen Sensor.
Jul 18, 2010 (9:45 pm)
Is their are difference with oxygen sensors? If their is, what is the difference.
I have a 92 accord 2.2L, FI, headers, downpipes, aftermarket catalytic converter, aftermarket resonator and a flowmaster muffler. When driving for 20 minutes, the CEL comes on and stays on. When I turn my engine off and restart it in about 15 minutes, the CEL stays off, then when I go for about 20 minutes, the light comes back on.
The car runs good with or without CEL so I was wondering if there were any differences with the 02 sensors. I just have to find out what is wrong, if anything is wrong.
I hope this makes sense.
By the way how many 02 sensors does a 92 accord have.

You might run this noise by a mechanic and if it is valve lifter noise, by all means get the valves adjusted.

The 90 Accord has the "Sport shift", and the 93 doesn't. That's the only difference I know of. The plugs (on the computer) may be the same, maybe not. I would guess the computer would work, but that's only a guess, sorry.

I don't think a 90 TCM can be interchanges with a 93 TCM. You really need to have the same part number to be somewhat sure. The 93 is similar to the 92, but quite a bit different from the 90/91 cars. "Some" of the correct part numbers are:
The LX had a 125hp engine (F22A1) and the EX had a 140hp engine (F22A4)
The factory TCU's on these cars were:
93LX - 28100-PX4-722
93EX - 28100-PX4-732
92LX - 28100-PX4-722 (same as 93LX)
92EX - 28100-PX4-731 (Oki) or 27100-PX4-732 (same as 93EX)
91LX - 28100-PX0-823 (for whatever reason, this TCU costs twice the price of all the others's from the dealer!)
91EX - 28100-PXO-833

My TCM is shot as well. I was told that 93 Hondas has lots of TCM issues. I found used ones online for under $200. How can I be assured it wont go bad again? I want my Honda to shift into gears normally. Please help, Thanks

The TCM issue with these cars (91-93) is that the TCM's (and the cars) are old but many are still on the road. The TCM has 5 capacitors inside it and these will leak and fail. If you take the cover off your TCM, look and see if there's dark colored goo or burned resistors on the circuit board - if there is, then you have the "usual" problem.
Before I bought another old one for $200, I would find out if it's been "recapped". If it hasn't, then it could fail tomorrow. A better option (in my opinion) would be to take the TCM out of your car and send it to one of the companies that will install new capacitors and resistors. You "could" recap one yourself, but that's not the easiest thing to do and the soldering can be a pain.
For a used, non-recapped, TCM I wouldn't pay more than $50 since it's a total gamble
Getting yours recapped should cost around $150
A new one from Honda (not worth the expense) is $600-$900 depending on the model.
