Help With Engine Codes

MPower7 · 09-26-2018, 10:01 PM

Hey Guys,

My car has test pipes and a stage 2 Alpine Tune. Just started getting this code below:

2741 Lambda probe heating controller diagnosis before Kat Bank 2
274F Lambda probe error Nernstleitung before Kat Bank 2

Is it ok to drive the car with these codes? What parts should I replace to fix the issue? Is it necessary to replace the parts even though the primary cats are coded out?

Thanks

Update:
Codes P3027 and P2247. Looks like it is the Bank 2 Sensor 1. Going to replace this. Should I do both Pre Cat Sensors or just he one throwing the code?
