Watch This Before Buying Another Bosch O2 Sensor! E92 M3 Oxygen Sensor Heater Resistance 2742 & 2743

Our E93 M3 has been having O2 sensor heater resistance error codes 2742 and 2743 before catalytic converter. We already replaced our oxygen sensors with the cheaper Bosch OEM equivalent part and I didn’t want to buy another set again, so I modified the connectors and was able to fix the check engine light issue for free. Just wanted to share an easy fix for anyone else who may have the same oxygen sensor heater resistance codes on their e90 M3 with the S65 V8 engine. Thanks for watching!

PSA: intermittent O2 codes and occasional misfires can be indicative of exhaust leak. I had these codes popping up and mechanics trying to fix it for literally years until I got smoke machine from Amazon and found two leaks (header to mid pipe and SAP valve). After fixing the leaks the issue was gone.

[@Sals_Garage]

Thx for sharing. We did not have an exhaust leak. The issue was the o2 sensor heater circuit which is an electrical issue.
