So the O2 sensor on my RX is kaput. CEL comes on when cruising but goes away when i plant it/put the map back into closed loop. From what ive seen OEM are stupid money so im considering an aftermarket one. Supershit have bosch ones with the bits to splice it in for $80 bones but Ive heard splicing/cutting/wiring in different sensors can cause issues with resistances and crap that makes them not ready right. Is there any truth to that or is it just forum myths?
My first plan is to get one from a pick a part for $30 with warranty and fingers crossed it works but plan B is a new one. Dont want to be cruising to HVC with a bung O2 sensor, bye bye fuel economy.
Cheers cubts
P.S if anyone has an O2 sensor from a 25D/some other engine that would work and is known to be working PM me lol
