i purchased an el 02 sensor thinking this was the right one for the rb20det but after further research i belive this is only good for the r33's. i went to repco and they dont know the part number for any replacement so i need help with a part number of any brand of sensor that would be suitable and not cost an arm and a leg.

thanks

Somebody please post up how to test the o2 sensor as I have narrowed my engines problems down to this or a couple of things.

Do you test it by driving with it unpluged? multimeter?

please help I can not afford mechanic after the cost of my engine replacement!

Don't be fooled into believing that parts for our imported nissan's are hard to come by because they are not! Seriously if u need a new O2 sensor go to Main North Nissan and into the parts area and ask. They will have everything u need and if not they can get it for you.

GoodLuck

yeh, im sort of in same boat as ross80. I thought getting 320 k's of a full tank was pretty standard but people saying otherwise so. Was just wondering where abouts the O2 sensor was exactly. I heard you can test it with a multimeter, but i have no idea where to find it.

Its in a rb20det 1989 gts-t type M

thx :O

ok this is what i read on how to test the 02 sensor.

on the sensor there are 3 wires, the center one is the one that talks to the ecu the other 2 are just to help heat it up faster. warm the car up with a 10-15min drive then while the car is still hot idle the car at about 2000rmp and put the multimeter on the center wire testing for volts. if it is working correctly it should jump between .3 and .7 volts. it jumps about as the car runs ritch then lean so dont expect a stable reading. it may go higer and lowwer by a bit but around that reading its doing its job.

oh yeah use a digital multimeter for best results.

too easy.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
