Help! Dashboard lit up after cat replacement

Ask the mechanic who worked on the car about the condition of the wires that were cut/torn from O2 sensor when Cat was stolen? Those loose wires can short out one of the computer's vehicles if they touch metal and because it had not failed when you dropped it off it means that swapping out that ECU to fix the problem might be covered by them partially or fully. Of course you don't have an ECU failure code so...

 

Maybe @ChapmanF has some ideas?

 

Well he needs clear out info for brake parts it looks like according to some scan pics . I would imagine till that happens you locked out of brakes as far as the finished repair. So it's like mostly completed ? Two brake parts in this model they both talk to car with wires or such . Only 1 piece replaced?

 

Tom, read the title of the thread. The cat was replaced. No brake parts were replaced.

 

I did . But you have brake codes now . Ripping out the 02 wires is a stretch to get to brake codes .do you now probably have issue with brakes on a gen3 .unless the cat steal involved ripping out a wheel sensor wire . But that 1365 or 4 won't come for that . Sooóo I didn't lok at other codes . On that list . Those 2 usually all I need . Unless 12V isn't but that would've been mentioned. Charge 12V secure all connections delete codes . What returns 1365 or 4 . And welp .

 

I have seen guys use an aftermarket o2 sensor and get the sensor wiring wrong since the colors do not match. I made a drawing to spell it out for them.

Also the Toyota wiring diagrams don't show the colors of the 4 wires built into the sensor extending to the factory wiring harness. This is where they get cut, eg the sensor wires, not the factory harness. The aftermarket sensor comes with a cross reference to the 4 wires on the factory sensor.

 

Can wiring up the O2 sensor wrong force brakes to code ?
