Hi Everyone these are probably stupid questions but

 

I have found that there are two braid covered cables that go from the Catalytic converters through the transmission tunnel floor underneath the car have been chopped off with presumably wire cutters, and are just hanging underneath the car,

 

Q1 : what purpose should they serve ?

 

Q2 : Is it a problem that they have been cut

 

Q3 :Is it possible to repair them ie: join them back together and if so how

 

Real novice question I know but would appreciate some help

 

 

I have also noticed that the bits of plastic either side at the front that attach to the front bumper are badly smashed what would they be called please so I can place a add in the Wanted section

 

Thanks in advance

 

 

Best Regards

They’re the cat converter temp sensors, to detect cat over heat.

 

It’s pretty common practice when the car has been de-catted to cut the cables as the temp sensors are normally stuck in the cats.

 

In short, nothing to worry about

Hi Nick

 

thanks for the reply, so can I just trim the cables so they don't hang down under the car or would there be any advantage to reconnecting them

 

Best Regards

No worries

 

I personally trimmed them down and fed them back through the holes in the floor and put some rubber bungs in the holes to seal them ip

Most common reason they get cut is the sensors ( which are only on jdm models ) are almost impossible to undo when removing the exhaust for any reason.

The sensors only bring a light on the dashboard, nothing else so insulate and tuck up, if they short out the light will come on.

Thanks Jeff, that would make sense as the previous owner had had a clutch fitted so I presume the garage cut them to remove the exhaust during the clutch replacement procedure, you would have hoped the garage concerned would have done something rather than just left them hanging under the car.

 

I will just tidy up and insulate the cut ends, presumably I can just trim the cable ends on the cats back to as short as possible.

 

Thanks for all advice also if anyone knows what the correct name for the plastics that are under the engine at the front of the car there appear to be three sections one over the centre section and one over each corner

 

Thanks again to all
