What is this on my dash

[batesandrew174]

Went over a bump and it shook the car a lil bit then this popped up. I saw the red light glaring at me and pulled over and checked all my fluids and they seem to be good car doesnt exert any problems. And on the highway hit a bump and it turned off hit another bump it turned back again

Im assuming then 02 sensor

Your car must be JDM rhd

 

[docjohn]

so that goes on when a left handed person drives a rhd....

 

[Old Guy]

Catalytic converter over temperature warning. Since it occurs over bumps it likely indicates a wiring fault or a sensor fault, not an actual over temperature. The sensor could be a thermistor or a simple bi-metallic strip that grounds out to indicate over temperature. Might be worthwhile investigating because a wiring fault may morph into something that affects other systems. You will need a JDM service manual to figure out what is what.

Thanks I think Im gonna have to check where to find the rhd 1991 honda nsx wiring diagram I went under the car today to look for loose connections but couldnt find any then went to the fuze boxes and couldnt find any missing although some were loose (by a extremly small margin) so I just left them be with a gentle push in then they were fine, drove the car and the light was gone then came back on when I revved the engine for highway speeds

On the highway the light did flutter (full light to ish no light) when I revved it

The wires for the sensor on in the right front of trunk behind the liner and punch through the floorpan to the sensors below.

Pulled this and it instantly came out

 

[batesandrew174]

Left the car on and touched the wires to find the second wire being touched makes light disapear so thats a sensor or wire right?

Did some more messing with wires and its the middle brown connector piece thats faulted whenever I push and pull it the light comes in and goes out

 

[drew]

The bottom connector is populated with another silver shielded wire like the middle one. You should have a sensor for each cat...

I don't know how they work, but I do have a JDM ETM (which is in Japanese) if you get into a bind.
