The have downstream sensor sir
How ever acoording to my research there should be diff bw readings of two so that no CEL lit up.
But there is a large distance bw two sensors of corolla and swift.
But i noticed that civics sensors are placed only at distance of 1 or half foot.
So both sensors are giving same reading to ecu
So ecu is detecting absent cat convertor
How ever my car idel perfectly
Pick increased thrice
And soud decrease twice
But i want to know if i drive the car as such does it causes any engine or ecu damage
Because i am deiving my gli 1.6 for 40000km without ecu and it is now 940000km driven and engine rum more smoothly silently
