help check engine light came on code 65 - Honda Prelude Forum

my check engine light came on today. i just picked my car up from getting the oil changed and the rear rotors replaced.

it is throwing code 65... i checked the forum and it said that it was the o2 sensor.

could the mechanic hit the o2 sensor while he was changing the oil? where is the sensor at? any pics?

any help would be greatly appreciated
thanks

Heated oxygen sensor (o2) CEL/MIL code is 1 or 41 or 43, and #43 is the highest possible in CEL/MIL code. There are no CEL/MIL #65

I looked in the shop manuel and there is no code 65, try rechecking the code and let us know

Okay, what year is your prelude? If its a 5th gen then its got OBDII and proably has different codes.

For a obdII equip'ed vehicle theres one in the front of the catylitic convertor and one on the back of it. Also if you dont know, its right under your car just right under your shifter.
